Renal Deletion of LRRC8/VRAC Channels Induces Proximal Tubulopathy
Authors: López-Cayuqueo Karen I. , Planells-Cases Rosa , Pietzke Matthias , Oliveras Anna , Kempa Stefan , Bachmann Sebastian , Jentsch Thomas J.
Published: July 2022

Significance Statement

Kidney cells are exposed to large changes in osmolarity and hence require efficient volume regulation. Volume-regulated anion channels (VRACs) mediate regulatory volume decrease, but their expression and function in the kidney remain enigmatic. VRACs, heterohexamers of LRRC8 proteins, also conduct metabolites. This paper describes the renal expression pattern of all five LRRC8 subunits and explores their roles in mouse models. Except for vasculature-restricted LRRC8C, all LRRC8 proteins are found along the nephron. Rather than in medulla, which experiences large osmolarity changes, VRACs are most highly expressed in proximal tubules, which have metabolite-conducting LRRC8A/D channels. Targeted disruption of either subunit injures the proximal tubule and produces Fanconi-like symptoms. VRACs may mediate nonspecific exit of organic compounds in this highly transporting nephron segment.

Background

Volume-regulated anion channels (VRACs) are heterohexamers of LRRC8A with LRRC8B, -C, -D, or -E in various combinations. Depending on the subunit composition, these swelling-activated channels conduct chloride, amino acids, organic osmolytes, and drugs. Despite VRACs’ role in cell volume regulation, and large osmolarity changes in the kidney, neither the localization nor the function of VRACs in the kidney is known.

Methods

Mice expressing epitope-tagged LRRC8 subunits were used to determine the renal localization of all VRAC subunits. Mice carrying constitutive deletions of Lrrc8b–e, or with inducible or cell-specific ablation of Lrrc8a, were analyzed to assess renal functions of VRACs. Analysis included histology, urine and serum parameters in different diuresis states, and metabolomics.

Results

The kidney expresses all five VRAC subunits with strikingly distinct localization. Whereas LRRC8C is exclusively found in vascular endothelium, all other subunits are found in the nephron. LRRC8E is specific for intercalated cells, whereas LRRC8A, LRRC8B, and LRRC8D are prominent in basolateral membranes of proximal tubules. Conditional deletion of LRRC8A in proximal but not distal tubules and constitutive deletion of LRRC8D cause proximal tubular injury, increased diuresis, and mild Fanconi-like symptoms.

Conclusions

VRAC/LRRC8 channels are crucial for the function and integrity of proximal tubules, but not for more distal nephron segments despite their larger need for volume regulation. LRRC8A/D channels may be required for the basolateral exit of many organic compounds, including cellular metabolites, in proximal tubules. Proximal tubular injury likely results from combined accumulation of several transported molecules in the absence of VRAC channels.

This educational topical review and Task Force report aims to address learning objectives of the International League Against Epilepsy (ILAE) curriculum. We sought to extract detailed features involving semiology from video recordings and interpret semiological signs and symptoms that reflect the likely localization for focal seizures in patients with epilepsy. This glossary was developed by a working group of the ILAE Commission on Diagnostic Methods incorporating the EEG Task Force. This paper identifies commonly used terms to describe seizure semiology, provides definitions, signs and symptoms, and summarizes their clinical value in localizing and lateralizing focal seizures based on consensus in the published literature. Video‐EEG examples are included to illustrate important features of semiology in patients with epilepsy.
Structural and Modal Analysis Of Adapter Plates For Hydraulic Hammers And Skid Steers Under Real Work Condition
Authors: Villa Yuri , Vook Trevor , L. Villa Jorge , Carbajal Pablo , Barrera Leonardo , Florez Max
Published: July 2022

In Perú the necessity of facility projects such as gas line installation for residents has increased the demand for use of Hydraulic Hammers (HH) with Skid Steers due to the lower amount of investment needed in comparison to other packs of machinery and the versatility. The ability to interchange hydraulic hammers and buckets to complete the demolition and cleaning stages offers higher productivity than manual operations for contractors. For that reason, the virtual design software Inventor Professional was used to design a suitable adapter plate with adequate resistance and durability which has a direct impact on the structure of the hydraulic hammer and the hydraulic arm of the skid steers. Simultaneously, a basic animation was developed to explain the effect of the operation style over the hydraulic hammer and the adapter plate. Finally, for this development, the construction of an adapter plate as a fuse in the system was considered in case operators exceed the resistance capacity of the hydraulic hammer structure.

Background: GCs remain regularly used drugs to treat rheumatoid arthritis (RA). While weight gain and hypertension are known to be common adverse events ofthe treatment with higher GC dosages, the effects of low dose(i.e.≤7.5mg/day)treatment over longer periods of time(i.e.≥24months)as seen in RA have not been fully elucidatedyet.While some observational studies have been conducted,thesestudies arelikelysubject toconfoundingby indication–i.e., patients with high disease activityusuallyreceive higher doses of GCs,making it impossible to discriminate between the effects of the drugandthe disease. Objective: To conduct a pooled analysis offivelong-termrandomized controlled trials (RCTs) in RA which comparedlow doseGCs to placeboor no GCin a double-blind fashionin order to evaluatethe effects onweight andblood pressureaftertwo years. Methods: We will include the following RCTs, all of which had a duration of two years:The Glucocorticoid Low Dose Outcome in Rheumatoid Arthritis Trial (GLORIAtrial,Boers et al.),1Arthritis and Rheumatism Council Low-Dose Glucocorticoid Trial (ARCtrial,Kirwan et al.),2the Intramuscular MethylprednisoloneStudy(Choy et al),3the Low Dose Prednisone Trial (LDPTtrial,Wassenberg et al.),4and the BARFOT Trial(Svensson et al.).5The primary analyses will be based on analysis of covariance (ANCOVA)modelscontaining theterms, treatment, baseline value of the outcome, and trial ID, andwill assess the effect oflow dose GCsontwomajoroutcomes:change inweightfrom baselineuntil two years(kg)andchange inmean arterial pressure (MAP; in mmHg; same time frame). If thereisa significant difference between GC andcontrolgroups in MAP,we will perform a sensitivity analysis to investigate the components (i.e.,systolicblood pressureand diastolic blood pressure). In furtheranalyses,other covariateswill beinvestigated, e.g.,GC dosage, form of application (oral vs. subcutaneous),age,sex,anddisease activity.Sensitivity analyses will also be conducted to underpin the findings.

Problems of Machine Translation Systems in Arabic
Authors: Shaikhli May Al
Published: July 2022

the human need for language translation has been increasing because of knowledge fields’ expansion and open communications across all countries throughout the world. Accordingly, the traditional translation has become insufficient and machine translation is the best alternative. However, despite its astounding development during the past decades, as an inevitable alternative, machine translation still faces many challenges that make it incomparable with human professional translation. This indicates that machine translation in all its types has to be supported by highly-developed tools that can enhance its effectiveness. This study showed the advantages of machine translation, discussed some of its most common challenges, and accordingly introduced some recommendations that should be taken into account to improve its effectiveness regarding Arabic Language.

Psychological Features of Different Personality Types of Convicts Infected with Tuberculosis, depending on the Severity of Suicidal Risk
Authors: Ilinykh N. , Ganishina I.S. , Maryin M.I.
Published: July 2022

The article discusses the psychological features of suicidal risk in various personality types of convicts infected with tuberculosis and serving their sentences in medical correctional institutions of the penal system. The empirical study revealed that such convicts have low levels of suicidal risk. Using cluster analysis, three personality types of convicts infected with tuberculosis were identified, depending on the severity of their suicidal risk: demon-strative-affective, antisuicidal-maximalistic, untenable-pessimistic. The demonstrative-affective type is characterized by denial of the disease, an indifferent attitude to it, a gener-ally blaming attitude towards medical personnel and the treatment he/she gets. The antisui-cidal-maximalist type is characterized by a desire for life, an orientation towards a complete cure from the disease in a shorter time. The untenable-pessimistic type, although valuing his life, does not show high interest in speedy recovery or following the recom-mendations of the attending physicians. Knowledge of the psychological characteristics of suicidal risk in different personality types of infected convicts will help provide them with psychological support in institutions of the penal system.
Subjective Predictors of Cadets’ Behavior Patterns in Situation of Cognitive Dissonance
Authors: Kudinov S.I. , Burtsev A.O. , Kudinov S. , Maryin M.I. , Khanalieva D.
Published: July 2022

The article presents the results of an empirical study revealing the role of different personal qualities in the choice of certain patterns of behavior in situations of cognitive dissonance. In the study on a sample of cadets (N=217), it was found that a certain ratio of personality qualities such as self-esteem, anxiety and locus of control are fundamental predictors in choosing a constructive or destructive strategy of behavior in a situation of cognitive dissonance. It has been empirically proved that the correlation between low anxiety, adequate self-esteem and internal self-regulation is typical for cadets choosing a constructive model of behavior in situations of cognitive dissonance that ensures the successful solution of a cognitive task. Cadets with a destructive strategy of behavior in such a situation have a statistically significant correlation of moderate or pronounced anxiety, inflated self-esteem and external regulation, which impedes getting out of a complex cognitive construct. And finally, the avoidant behavior model in cognitive dissonance is demonstrated by respondents with high anxiety, low self-esteem and external locus control. On the basis of the data obtained, a conclusion is made about the development of a special program for correction and enhancement of the emotional-volitional sphere of cadets during their studies at the university.
ECOLOGICAL APPROACH IN YOUTH EDUCATION IN THE FIELD OF NATIONAL DEFENCE
Authors: Katane Irēna , Kreija-Gaikšte Sandra
Published: July 2022

The current geopolitical situation in the world, and especially in Europe, highlights the sustainability of each society and country in the present dimension and sustainable development in the future. The ability of the society of the future to develop itself, to provide for the sovereignty of its country, to strengthen its economy, to raise its level of prosperity, to preserve and enrich its culture is shaped and developed in today's schools and universities as the next generations are learning and studying there. They will be managing the country in the future, taking care of sustainable development of the society, the economy of their country, its security and defence, being at the heart of our country's future society. Therefore, innovations in the content of general secondary education in Latvia are needed by introducing a new subject of National Defence Training in schools. The legal basis for this has already been prepared in the form of laws and other regulations. Model curricula for general secondary education and the Youth Guard have been developed. Since in global forums as well as in scientific publications at the end of the 20th century the ecological paradigm has been justified as a transdisciplinary paradigm, but the ecological approach in human thinking, in promoting the development of children/youth, in all kinds of activities (in all areas of human activity, including education) has been justified as an imperative, which has become more and more relevant in the 21st century, the aim of the research was to substantiate the diversity of ecological approaches in the education of young people in the field of national defence. The results of the research demonstrate that the ecological approach is visible in the development of the national defence content. It is also common in the justification for the many aspects of the national defence learning environment.

PENGGUNAAN METODE BELAJAR BERBASIS GAME SEBAGAI UPAYA MEMECAHKAN PROBLEMATIKA DALAM PEMBELAJARAN SEJARAH
Authors: Vinidiansyah Ananda Savira , Nurhaniah Nurhaniah , Andi Andi
Published: July 2022

This study aims to find out about the implemention of game-based learning methods that can be used by history teachers to create better and interesting learning activities, this is because many teachers are less skilled in using learning methods. In fact, if you look closely, there are various kinds of learning methods that can be used to lure students to be more active in creating a pleasant learning atmosphere, especially in history learning, such as the use of game-based learning methods. The method used in this study is a research method with a descriptive qualitative approach. The data sources used in this study are classified into two sources, namely primary data sources and secondary data sources. Primary data sources were obtained through interviews with informants, namely five students who had experience learning game-based history at the X, XI, and XII grades of SMAIT Mentari Ilmu Karawang, SMAI Al-Azhar Summarecon Bekasi, SMAN 13 Tangerang, SMAN 1 Teluk Jambe Timur, and SMAIT Al-Irsyad Karawang. Meanwhile, secondary data sources are obtained through documents in the form of books, scientific journals or studies that are relevant to the research theme. The results of this study indicate that from various schools, teachers in carrying out learning, especially in history subjects, have used game-based learning methods. Game-based learning used by teachers are games such as Kahoot, Quizizz, WorldWall, QuizWhizzer, Educandy and some even play guessing pictures. The game can be used easily without taking a long time. Learning history by using games can make the learning atmosphere more exciting and challenging. So game-based learning can be used by teachers to avoid monotonous and boring activities. With this game-based learning, especially in history lessons, it can change the public's view of the image of history which was previously considered to be of the view that learning history is not too exciting.

The Covid-19 pandemic hit Indonesia since mid-March 2020 and caused changes to various fields. One of the areas affected is education. Learning activitiess that were originally done face-to-face or directly, are now turning into distance learning or online learning. In the study of history, especially local history, online learning experienced quite complex challenges.  This research aims to analyze the problems or challenges experienced by history teachers in East Java in developing life-based history learning designs. This research uses qualitative descriptive methods. The subject of this study is a high school history teacher in East Java. Data collection techniques are carried out using observations, interviews and documentary studies. Data analysis is done by collecting data reduction data, presenting data and verifying the resulting data. As a result, there are obstacles faced by teachers and make learning designs such as doing learning planning, determining, material, choosing media, teaching materials to learning resources. The solution to the challenges faced is to make adjustments to existing conditions by making local history learning designs based online. The initial stage is to analyze basic competencies on the syllabus. The second stage is to determine the indicator of competency achievement (ICA). After the teacher has a ICA, it can determine the material, media, learning resources to learning strategies to create local history learning based on life.

RELEVANSI IDE THE OPEN SOCIETY KARL POPPER DAN MULTIKULTURALISME DALAM PEMBELAJARAN SEJARAH
Authors: Azifambayunasti Azril
Published: July 2022

The Open Society by Karl Popper is an idea that opposes any kind of oppression and to-talitarianism, so that what is called an open society will be realized, a society that priori-tizes freedom but remains in the corridor of law and ethics. The Open Society is an idea that opposes socialism and capitalism at the same time. As an important idea in the modern age, The Open Society Popper must be able to use in life, just like knowledge that has an axiological basis. This idea is also closely related to democracy which up-holds individual freedom while still being controlled by law. On the one hand, The Open Society can be implemented in the education democracy movement, which is then called multicultural education, with kind of values that accommodate the freedom and equality of individual rights in society. The purpose of this study is to discuss the idea of The Open Society and its relevance to historical education, especially regarding multiculturalism. This discussion was reviewed using the literature study method. The results of this analysis show that The Open Society Popper can be used as a basis for multicultural education because it gives high respect to individual freedom and opposes domination by certain groups, while still respecting the law.Open Society menurut Karl Popper adalah sebuah gagasan yang menentang segala bentuk penindasan dan totalitarianisme, sehingga akan terwujud apa yang disebut masyarakat terbuka, masyarakat yang mengutamakan kebebasan namun tetap dalam koridor hukum dan etika. Masyarakat Terbuka adalah sebuah ide yang menentang sosialisme dan kapitalisme pada saat yang bersamaan. Sebagai sebuah ide penting di era modern, The Open Society Popper harus dapat digunakan dalam kehidupan, seperti halnya pengetahuan yang memiliki landasan aksiologis. Gagasan ini juga erat kaitannya dengan demokrasi yang menjunjung tinggi kebebasan individu dengan tetap dikendalikan oleh hukum. Di satu sisi, Masyarakat Terbuka dapat diimplementasikan dalam gerakan demokrasi pendidikan, yang kemudian disebut pendidikan multikultural, dengan nilai-nilai yang mengakomodasi kebebasan dan persamaan hak individu dalam masyarakat. Tujuan penelitian ini adalah membahas mengenai gagasan The Open Society dan relevansinya dengan pendidikan sejarah, khususnya perihal multikulturalisme. Pembahasan ini dikaji menggunakan metode studi pustaka. Hasil analisis i menunjukkan bahwa The Open Society Popper dapat dimanfaatkan sebagai landasan pendidikan multikultural karena memberikan penghargaan yang tinggi terhadap kebebasan individu dan menentang penguasaan oleh kelompok tertentu, dengan tetap hormat pada hukum.

Authors: Ingles Candido J. , Urbán Dori J. A. , Castanheira João , Garcia-Fernandez José Manuel
Published: July 2022

El objetivo de este estudio fue validar la versión portuguesa del Cuestionario de Evaluación de Dificultades Interpersonales para Adolescentes (CEDIA) usando una muestra de 369 estudiantes de 12 a 18 años (51 % chicas; M = 14.50; SD = 1.60). El análisis factorial exploratorio de componentes principales y rotación oblimin, identificó 4 factores relacionados (Asertividad, Relaciones Familiares y Amigos, Relaciones Heterosexuales y Hablar en Público) que explicaron el 43.45 % de la varianza. En el análisis factorial confirmatorio se analizaron tres modelos predefinidos: el modelo nulo (M0), el modelo de un factor (M1) y el modelo de cuatro factores relacionados (M4). M4 fue el modelo que mejor se ajustó a los datos. La consistencia interna y la fiabilidad test-retest para la puntuación total del CEDIA fueron apropiadas. La correlación del CEDIA con la puntuación total del Inventario de Ansiedad Escolar (IAES) fue positiva y con un tamaño del efecto moderado. Este resultado fue similar para los tres sistemas de respuesta de ansiedad escolar medidos por el IAES y algo más variable para las cinco subescalas situacionales del IAES. Además, la correlación del CEDIA con la Social Anxiety Scale for Adolescents (SASA) fue positiva y pequeña para la subescala Aprensión y Miedo a la Evaluación Negativa (AFNE y moderada para la subescala Tensión e Inhibición en Situaciones Sociales (TISC). Finalmente, la correlación del CEDIA con el Internet Personality Inventory (IPI) fue positiva y moderada para la escala de Neuroticismo y negativa y pequeña para la escala Extraversión.

Nowadays, scientists concentrate on the cellular level of such response, studying molecular processes, often treating visual phenotypes as fully explored and obvious. The goal of this study was to challenge such believes and find a new visual phenotype of plants during their response to S deficit.Materials and Methods: The macroscopic and microscopic observation of Nicotiana tabacum plants grown under sulfur deficiency or control condition was conducted. Additionally, the absorbance spectrum of ethanol extracts from plant roots was measured.Results and Conclusions: In this study we showed that root color changes from colorless to yellow after transfer to S deficiency conditions. Microscopic observation of yellow roots showed that their color is a result of the yellowish deposits formation inside the root epidermis cells. Next experiments allowed to narrow down the list of chemicals responsible for the observed root phenotype to UV absorbing compounds. Our results, taken together with the data available in literature, pointed to the phenolic compounds as the most probable component of yellowish deposits responsible for change of root color during plant response to S deficiency. The physiological role of such accumulation is yet to be determined.

Published: July 2022

Background and purpose: Allometry is the study of the relationship of body size to shape, anatomy, physiology and behavior. Plants displaying allometric relationships between certain traits across different environments should have higher relative fitness then plants lacking these allometric relationships. We hypothesized that there are differences in external morphology between Plantago major L. (ssp. major) leaves exposed to different environmental conditions with variations for the leaf characters analysed.Materials and methods: Seven, linear dimensions on each leaf: leafblade apical width (AW), leaf-blade length (LL), leaf size (LS), leaf width (LW), leaf shape (LW/LL), the distance from the midrib to the neighboring vein (MV) and vein distances within a leaf (VD) were analysed. Here, besides analyzing allometric relationships between the common plantain leaves exposed to different environmental conditions, morphological data were also used for a regression analysis and for a cluster analysis.Results: In the reference area (Vinci village) leaves have significantly longer LL and they are significantly broader compared with leaves from polluted site (Pančevo). At both sites, LL decreased relatively to LS (i.e. negative allometry is character specific). This study also revealed that VD and LW/LL are developmentally and functionally integrated P. major leaf characters. Moreover, VD is under more selective pressure to adapt to current environmental conditions than LW/LL.Conclusions: Obtained data showed that leaf size is significantly related to both, developmental and environmental conditions. This indicates that plant species such as Plantago major L. (ssp. major) should be considered as reliable bioindicators in environmental quality monitoring studies.

Background and Purpose: The Motovun forest located in the Mirna river valley, central Istria, Croatia is one of the last lowland floodplain forests remaining in the Mediterranean area.Materials and Methods: Between 2011 and 2014  lepidopterological research was carried out on 14 sampling sites in the area of Motovun forest. The moth fauna was surveyed using standard light traps tents.Results and Conclusions: Altogether 403 moth species were recorded in the area, of which 65 can be considered at least partially hygrophilous. These results list the Motovun forest as one of the best surveyed regions in Croatia in respect of the moth fauna. The current study is the first of its kind for the area and an important contribution to the knowledge of moth fauna of the Istria region, and also for Croatia in general.
Distribution of rare Cystoseira species along the Montenegro coast (South-Eastern Adriatic Sea)

Published: July 2022

Background and purpose: Multiple studies have shown that Cystoseira species are sensitive to anthropogenic impact, and a decrease in their populations was observed, especially close to urban areas. To better understand status of such endangered and protected species, we studied the distribution of six rare Cystoseira species along the Montenegro coast: C. compressa subsp. pustulata, C. crinita, C. crinitophylla, C. sauvageauana, C. sqarrosa and C. tamariscifolia.Materials and methods: The study is based on field researches conducted through snorkelling and scuba diving along the Montenegrin coast during the period 1998-2009. In addition to the field work, we examined the published data for these species and the unpublished data from prof. Boris Antolić’s field diary.Results: Based on our 12-year-long investigations, we concluded that C. compressa subsp. pustulata, C. crinita, C. crinitophylla and C. sqarrosa are rare and endangered species along the Montenegro coast.Conclusions: The published data for C. sauvageauana is likely mistaken due to incomplete and poorly conserved algal material, while regarding the reference for C. tamariscifolia should be checked if the collected sample was preserved. Furthermore, we noted that the habitat destruction and the proliferation of sea urchin populations have the most dramatic negative impact on the biocenosis formed by such rare and endangered Cystoseira species.

Published: July 2022

Background and Purpose: During the preparation of a coenological paper concerning the tall-herb vegetation of the Balkans, it emerged that some syntaxa were invalidly described in their original papers, while some other synataxa had been forgotten or considered invalid according to the current phytosociological literature even if they had been validly published in their original papers. The present study deals with the nomenclatural problems of the Rumicetalia balcanici Lakušić 1973, a neglected order of the montane tall-herb vegetation, and those of all its related lower-rank syntaxa.Materials and Methods: All published papers that treated the nomenclatural issues regarding the tall-herb vegetation in the Balkans were analysed. The nomenclature adjustments were made in accordance with the rules of the Code of Phytosociological Nomenclature (ICPN). The original relevés presented in this paper were carried out using the Braun-Blanquet phytosociological approach.Results and Conclusions: The nomenclature adjustments made in the paper result in the validation of the order Rumicetalia balcanicae and of four alliances: Rumicion balcanici, Ranunculion serbici, Cicerbition pancici and Petasition doerfleri. The validity of the alliance Cirsion appendiculati Horvat, Pawlowski et Walas 1937 was here confirmed while the name citation Geion coccinei Horvat in Quezel 1969 was here given for the first time. Finally several tall-herbs association were here validated and some others were proposed as new.
The influence of crown defoliation on the variability of some physiological and morphological properties of Silver fir (Abies alba Mill.) seeds in the seed zone of Dinaric beech-fir forests in Croatia
Authors: Gradečki-Poštenjak Marija , Ćelepirović Nevenka
Published: July 2022

Abstract Background and Purpose: Negative anthropogenic influence on the environment became visible in the 1980s and the result was the emergence of forest degradation. Silver fir (Abies alba) is highly sensitive to atmospheric and pedospheric pollution and it is one of the most endangered tree species in the entire Europe. The aim of this research was to determine the influence of different levels of crown defoliation on the phenotypic variability between and within the populations of silver fir in the zone of Dinaric beech and fir forests. Material and Methods: Within the area of silver fir forests in the Forest Administrations of Delnice, Senj and Split, permanent experimental plots were established in order to monitor the influence of different levels of crown defoliation on some properties of seeds: germination capacity, the percentage of fresh ungerminated seeds, rotten and decayed seeds, empty seeds and 1000 seed weight. Statistical analysis was carried out by parametric and non-parametric. Various models of variance analysis were carried out in the analysis of the variability of traits. Results: The average germination capacity of silver fir seeds for the investigated area was 27.9 %, and ranged from 16.2 to 39.3 %. CV was high and indicated a great heterogeneity between the provenances. Average values of fresh ungerminated seeds were 12.6 %, and ranged from 9.1% to 19.6%. Average values of dead seeds were 16.1 % and ranged from 8.2 to 28.5%. The provenances from the area of Gorski kotar showed the largest portion of dead seeds, which was the area with the highest index of forest decline. The average value of empty seeds in the researched area was 43.4% and it ranged from 29.9% to 63.0%. CV ranged from 33.9% to 74.0% indicating a heterogeneity within the provenances. The share of empty seeds was influenced by the air pollution and the presence of insects on generative organs, and had a negative influence on the germination capacity. The average TSW in the researched area was 57.4 g and ranged from 49.4 g to 73.6 g. Duncan’s test confirmed the variability between the provenances for all investigated seed properties. Conclusions: A statistically significant intrapopulation and interpopulation variability of physiological seed properties was determined in all studied provenances and the influence of different levels of crown defoliation on their variability was not determined. Considering the morphological properties of seeds, a statistically significant variability between the provenances and the levels of crown defoliation was determined as well as for the interaction of these two factors.
