Published: December 2023

Cultivated plants generally are a poor source of dietary selenium (< 0.1 mg/kg wet weight). In this work the influence of sodium selenate on selenium distribution in the chicory (Cichorium intybus L.) cultivars ‘Anivip’ and ‘Monivip’ was studied in an aeroponic system in a greenhouse. The plants roots were moistened every fifteen minutes with a Resh nutrient solution with added selenium (10 mg L-1) in the form of sodium selenate. The content of total selenium in chicory roots and leaves was studied after different periods of time and different temperatures of exposure to the selenium enriched nutrient solution. In two separate experiments chicory was treated with selenium enriched nutrient solution for 40 days at 10 ºC in the slow growing phase, and for 5, 7 and 10 days at 20 ºC in the developmental phase at the beginning of formation of the flower stem. The concentration in leaves increased with time during plant growth, and in Se treated groups was 370 and 139 mg kg-1 in ‘Anivip’ and 460 and 205 mg kg-1 in ‘Monivip’ leaves after 40 and 10 days of exposure, respectively. A smaller increase in selenium content was obtained in roots, namely to 73 and 46 mg kg-1 in ‘Anivip’ roots and to 87 and 46 mg kg-1 in ‘Monivip’ roots after 40 and 10 days of exposure, respectively. All results are expressed on a lyophilised matter basis. In long and short term treatment, the selenium content in ‘Monivip’ cultivar was higher than in ‘Anivip’. No visible toxic effects on the chicory plants were observed.
Evaluation of cacao-pudding as a probiotic food carrier and sensory acceptability properties
Authors: IRKIN Reyhan , GULDAS Metin 
Published: December 2023

A number of health benefits have been claimed for probiotic bacteria such as Lactobacillus acidophilus, Bifidobacterium spp. and Lactobacillus casei. These benefits include anti-mutagenic effects, anti-carcinogenic properties, improvement in lactose metabolism, reduction in serum cholesterol and immune system stimulation. Because of the potential health benefits, these microorganisms are increasingly being incorporated into dairy foods. Several studies in recent years have shown the benefits deriving from the ingestion of probiotics and a large number of products containing lactobacilli and bifidobacteria formulated. The purpose of this study was to develop a pudding with cacao to which probiotic microorganisms were added and investigate the viability of probiotic microorganisms during the shelf-life along 25 days at 4 °C. Organoleptic properties of the puddings were also evaluated during the storage. Bifidobacterium animalis ssp. lactis LAFTI B94, Lactobacillus acidophilus LAFTI L10 and Lactobacillus casei LAFTI L26 cultures were activated and incorporated into the product. Pudding with cacao was shown to be a good vehicle for the delivery of Bifidobacterium animalis ssp. lactis, Lactobacillus acidophilus during 15 and 25 days respectively and these microorganisms did not interfere in the sensorial preferences of the product except Lactobacillus casei. The pH values and organoleptic scores of the pudding samples, except Lactobacillus casei LAFTI L26 containing ones, did not change for 20 days during the storage period, statistically (P<0.01). The pudding containing Lactobacillus casei LAFTI L26 was taken the lowest sensorial scores. The all samples were lost their organoleptic properties at the 25 days of storage period.
Reduction of the lenght of 1 RS.1BL translocation in the bread wheat variety "Yugoslavia"
Authors: SINKOVIČ Tomaž 
Published: December 2023

This study was conducted to estimate the survival of 1RS.1BL wheat-rye translocations in a bread wheat (Triticum aestivum L. em Thell.) variety "Yugoslavia" including "Aurora" as a donor of translocation in its pedigree. The cultivar was cytologically checked by N-banding for the presence of 1RS.1BL translocation. Fluorescence in situ hybridization using total genomic biotin labelled rye DNA as a probe was used for identification and localisation of the translocation breakpoints and their size. At metaphase and interphase the introgressed rye segment was observed and photographed. Digital image analysing system with cooled CCD camera was used for overlapping the pictures of the probe signals and counterstained wheat chromosomes and helped to determine the position and extent breakpoint of this translocation. The translocation in this variety is probably restricted to the NOR region only, unlike in other 1RS.BL translocation lines ("Kavkaz") where the translocation carries at least the major part of the 1RS arm.

Authors: BAŠA ČESNIK Helena , VELIKONJA BOLTA Špela , GREGORČIČ Ana 
Published: December 2023

In the period from 2005 to 2009 225 samples of apples, lettuce and potatoes from Slovene producers included in integrated pest management (IPM) were analysed for plant protection product (PPP) residues. The samples were analysed for the presence of more than 200 different active compounds using four analytical methods. In 38.7% of apple samples residues were not detected, 58.6% of apple samples contained residues lower than or equal to Maximum Residue Levels (MRLs) while 2.7% of apple samples exceeded MRLs. In 84.6% of lettuce samples residues were not detected, 12.3% of lettuce samples contained residues lower than or equal to MRLs while 3.1% of lettuce samples exceeded MRLs. In 98.0% of potato samples residues were not detected, 2.0% of potato samples contained residues lower than or equal to MRLs and no potato samples exceeded MRLs. Multiple residues were found only in apples and lettuce. The trend observed during the years was the decrease of sample portion of samples containing multiple residues in apples from 2005 to 2008. The most frequently found active substance in apples and lettuce was dithiocarbamates. In potato only phosalone was found.
Značilnosti diatomejske zemlje kot naravnega insekticida za zatiranje skladiščnih škodljivcev
Authors: ROJHT Helena , HORVAT Aleksander , TRDAN Stanislav 
Published: December 2023

Diatomejsko zemljo uporabljajo v številne namene, med drugim tudi kot bioinsekticid za varovanje uskladiščenih pridelkov. Ta zemlja nastane z mletjem sedimentnih kamnin, imenovanih diatomiti. Obstaja veliko vrst diatomejske zemlje, a le zemlje z manj kot 7 % kristalnega SiO2 so primerne za zatiranje škodljivcev. Diatomejska zemlja ni toksična za sesalce, dolgotrajno varuje živež pred škodljivimi žuželkami, za njen nanos se uporablja približno enaka tehnologija kot pri klasičnem nanosu insekticidov in se med predelavo zlahka odstrani z živeža. Med nekaj negativnimi lastnostmi gre izpostaviti dejstvo, da zmanjša hektolitrsko maso zrnja (zniža nasipno gostoto zrnja), ki je glavno merilo kakovosti zrnja. Diatomejska zemlja ima velik absorpcijski potencial in se veže na epikutikularne voske žuželk, zato deluje praktično na vse škodljivce, ki imajo kutikulo zaščiteno z voski.

Published: December 2023

‘Žilavka’ has been grown in Bosnia and Herzegovina since the XIVth century and is exploited for wine production. Although not sufficiently studied, this grapevine cultivar has high economic potential for the country. Five survey missions resulted in the collection of eighty ‘Žilavka’ accessions that varied in terms of names and characteristics. Because of the unknown origin of the cultivar, these accessions were analyzed with microsatellites markers in order to obtain a standard ‘Žilavka’ genotype. AFLP markers were used to investigate the genetic basis of variability within the cultivar. ‘Žilavka’ grapevines were screened on 14 microsatellite loci, thus revealing 4 different genotypes arising from mutations observed at 10 polymorphic loci. AFLP analysis of 52 ‘Žilavka’ accessions revealed 35 different genotypes, with an average polymorphism of 57 %. Cluster analysis showed no grouping of different Žilavka accessions according to their names, characteristics or collection locations. The standard ‘Žilavka’ genotype was further compared to 211 cultivars from Slovenia (49), Austria/Germany (20), France (13), Portugal (27), Croatia (19), Greece (32), Spain (21) and Italy (30) in order to assess their genetic relationships. In pairwise comparisons, the highest genetic similarity was found with Slovenian cultivars ‘Glera’ and ‘Briška Glera’ (64 %) and the highest genetic dissimilarity (100 %) with two Italian cultivars, ‘Nebbiolo Lampia’ and ‘Vespolina’. Inventory, collection and genetic characterization of ‘Žilavka’ accessions are important steps towards cultivar standardization, identification of parental cultivars and investigation of cultivar origin, required for its sustainable use.
Pisana polonica (Harmonia axyridis [Pallas], Coleoptera, Coccinellidae) - invazivna koristna vrsta

Published: December 2023

V začetku novembra 2011 smo v okolici Ljubljane na zidovih posameznih stanovanjskih hiš opazili množičen pojav polonic. Nekaj primerkov smo izlovili, da bi določili vrsto. Na podlagi stereomikroskopskega pregleda in ob uporabi dostopne literature smo potrdili vrsto Harmonia axyridis (Pallas). Vrsta pri nas še nima slovenskega poimenovanja, zato v tem prispevku predlagamo uporabo imena pisana polonica, ki izhaja iz angleškega poimenovanja Harlequin ladybird. V prispevku je opisana bionomija vrste in njen pomen za Slovenijo. Pisana polonica je bila v Evropo vnesena z namenom uporabe v biotičnem varstvu rastlin. V nekaterih državah poročajo o škodljivem hranjenju odraslih osebkov pisane polonice z mehkimi plodovi nekaterih sadnih vrst, kot tudi grozdnimi jagodami. Vrsta H. axyridis postaja nadležna v urbanem prostoru. Nekateri tuji viri navajajo, da s svojimi izločki onesnažuje zidove in opremo, povzroča lahko tudi alergijske reakcije pri ljudeh.

Published: December 2023

Začetki načrtnega zbiranja trav in metuljnic segajo v 50 leta prejšnjega stoletja, ko so iz zbranega materiala kasneje požlahtnili prve slovenske sorte trav in metuljnic. V prispevku je poleg zgodovine prikazano sedanje delo genske banke krmnih rastlin in nekateri rezultati vrednotenja genskih virov v zadnjem desetletju. Za najprimernejši način zbiranja genskih virov so se pokazale večdnevne odprave, katerih cilj so lahko travniki ali kmetije, ki še pridelujejo lokalne populacije oziroma stare sorte kmetijskih rastlin. Trenutno v genski banki hranimo 761 vzorcev krmnih rastlin, od tega je 281 metuljnic, 352 trav, 73 travniških zeli in 55 krmnih poljščin. Večina krmnih rastlin je tujeprašnih, kar otežuje množenje vzorcev zaradi potrebe po prostorski izolaciji. Obnova starih vzorcev je in bo v prihodnje velik izziv tudi naše genske banke. Pri ocenjevanjih travniškega mačjega repa (Phleum pratense), navadne pasje trave (Dactylis glomerata L.), plazeče detelje (Trifolium repens L.), navadne nokote (Lotus corniculatus L.) in navadne turške detelje (Onobrychis viciifolia Scop.) smo med posameznimi ekotipi ugotovili dokaj veliko morfološko raznolikost. Ekotipi se med seboj razlikujejo tudi po kemijski sestavi, krmni vrednosti in drugih agronomskih lastnostih.

Authors: PELENGIĆ Radojko , KORUZA Boris 
Published: December 2023

Zbiranje in ohranjanje genskega fonda rodu Vitis je pomembna naloga, ki smo se je v Sloveniji načrtno lotili leta 1980. Možnost izbire med različnimi genotipi omogoča nadaljevanje žlahtniteljskega dela, tako glede selekcije (odbire klonov žlahtne vinske trte), kot tudi glede vključevanja zanimivih lastnosti v že obstoječe genetske kombinacije (pridobivanje odpornejših sort). Predvsem pri starih domačih sortah žlahtne vinske trte je pomembno, da smo jih v čim večjem številu ohranili in zaščitili preden so povsem izginile iz naših vinogradov. Posebej to velja za avtohtone vinske sorte žlahtne vinske trte, ki so izključno del naše naravne dediščine in jih v drugih vinorodnih deželah ne najdemo. Slovenska genska banka žlahtne vinske trte je razdeljena na dva dela in sicer na kolekcijo starih sort ter na kolekcijo novih, doma selekcioniranih klonov žlahtne vinske trte ter podlag. Kolekcije in situ so posajene na treh lokacijah, kot kolekcija z okoli petdesetimi starimi domačimi vinskimi sortami žlahtne vinske trte, ki se sproti dopolnjuje v Ampelografskem vrtu BF v Kromberku pri Novi Gorici, kot kolekcija 29 novih doma selekcioniranih klonov žlahtne vinske trte na lokaciji Litmerk pri Ormožu in kot kolekcija 10 novih doma selekcioniranih klonov žlahtne vinske trte v Vipavi. Poleg treh glavnih lokacij, se kolekcije nahajajo še na štirih pomožnih lokacijah, kot kolekcije novih doma selekcioniranih klonov žlahtne vinske trte v Pleterjih, Čurilah pri Metliki in Gadovi peči, ter kot kolekcija starih domačih vinskih sort žlahtne vinske trte v Dobrovem v Goriških Brdih. Vse zbrane akcesije so vključene v program ampelografije, ki se opravlja po predpisani metodiki deskriptorjev, ki jih izdajajo mednarodna organizacija za vinsko trto in vino (OIV), mednarodni inštitut za rastlinske genske vire (IPGRI) in mednarodna zveza za zaščito novih sort rastlin (UPOV), ki skupno obsega opis 130 morfoloških značilnosti. Delo poteka postopno, osnovno opisovanje pa je bilo razširjeno s popolno filometrijo. Do leta 1999 smo bili kot sodelavci vključeni tudi v evropski projekt GENRES, vse naše zbrane vinske sorte pa so vpisane v »Mednarodni seznam sort vinske trte in njihovih sinonimov«, ki ga je izdala mednarodna organizacija za vinsko trto in vino.
Effect of drought stress and selenium spraying on photosynthesis and antioxidant activity of spring barley
Authors: HABIBI Ghader 
Published: December 2023

This paper reports the effects of selenium (Se) application on some physiological characteristics of barley (Hordeum vulgare L. cv. Rihane-03) exposed to drought stress. Foliar application to barley at 30 g selenium ha-1, as sodium selenate, increased significantly shoot dry weight and relative water content in well-watered plants. A remarkable reduction in dry weight of water-stressed plants was associated with significant decrease in maximal efficiency of PSII (Fv/Fm), stomatal conductance (gs) and net CO2 assimilation rate (A). Activity of antioxidant enzymes was increased by drought stress significantly. Amounts of malondialdehyde (MDA) and hydrogen peroxide (H2O2) remained unchanged in Se-supplemented water-deficit plants obviously because of an efficient scavenging following significant enhancement of catalase (CAT) and glutathione peroxidase (GSH-Px) activities. These results indicate that an application of selenium was favorable for biomass accumulation of barley plants under well-watered conditions. However, it did not significantly affect dry matter accumulation under drought stress, but Se-supplemented water-deficit plants exhibited better protection from oxidative damage because of higher CAT and GSH-Px activities and lower level of lipid peroxidation. These results suggest that selenium application can improve antioxidant defense system under drought stress conditions, and it may be recommended for arid and semiarid regions.

Published: December 2023

The main agricultural importance of Trichoderma species was not so far away mainly suppression of plant diseases. Novel investigations emphasize their potential to stimulate plant growth independently of suppression of any plant disease. However, Trichoderma spp. and even biotypes of same species vary between each other in its effectiveness both in the control of plant pathogenic fungi and in the promotion of plant growth and increasing yield. The subject of this study was to evaluate growth promoting effect of two indigenous T. viride stains STP16 and STP8 on cabbage and red beet. Increment of fresh and dry weight accomplished by STP16 was statistically significant so, it could be concluded that growth enhancement of 27% at red beet and 29% at cabbage is significant.
impact of environmental factors on the infection of cereals with Fusarium species and mycotoxin production – a review
Authors: POPOVSKI Sasho , CELAR Franci Aco 
Published: December 2023

Several phytopathogenic Fusarium species occurring worldwide on cereals as causal agents of ‘head blight’ (scab) of small grain cereals and ‘ear rot’ of maize, are capable of accumulating, in infected kernels, several mycotoxins some of which of notable impact to human and animal health. Fusarium graminearum, F. culmorum, F. poae, F. avenaceum and Microdochium nivale predominantly cause Fusarium diseases of small-grain cereals. Maize is predominantly attacked by F. graminearum, F. moniliforme, F. proliferatum and F. subglutinans. The review is focused on the influence of climatic variables, particularly temperature, humidity and rainfall on growth, reproduction, survival, competitive ability, mycotoxicity and pathogenicity of Fusarium fungi commonly isolated from wheat, barley and maize.

Published: December 2023

In order to examine the effect of source and sink limitation and post anthesis water deficiency stress in determining of grain yield potential in nine modern bread wheat cultivars in the west of Iran with arid and semi-arid weather that is one of the main centers of crop diversity in the world, a split plot-factorial experiment based on randomized complete block design with three replications was used in crop year 2010-2011. Three treatments includes: control, flag leaf removal and removal of half of each spike was applied in the field research campus of agriculture and natural resources of Razi University. Water deficiency stress was started at anthesis and continued till physiological maturity (withholding of irrigation). Water deficiency caused significant reduction in the grain yield and the 1000 grain weight and caused significant increase in the number of fertile spikelets per spike. Flag leaf removal (source limitation) treatments showed that flag leaf contribution in grain yield production during grain filling in control and post-anthesis water deficiency stress condition were 10.1% and 13.4% respectively. In both conditions removal of spikelets spike-1 (sink limitation) treatment had higher significant effect on fertility of spikelets, grains spike-1, grain yield spike-1 and 1000 grain weight than flag leaf removal. Flag leaf removal treatment in some cultivars not only had no reduction effect on grain yield and 1000 grain weight but also increased them. These results may be due to an increase in photosynthesis rate of remaining leaves and/or increase in amount of carbohydrates remobilization that is stored in the stems. This phenomenon is called the compensatory effect. In both water regimes, there was a correlation between lower grain weight, no grains spike-1 and fertile spikelet spike-1 and lower yield potential of ‘Chamran’ cultivar. But, ‘Zarin’ and ‘Pishgam’ cultivars due to higher grain yield potential in post-anthesis under water deficiency stress and control, performed more studies, to advise farmers to cultivate them. There are probably better than any other cultivars that are common in these regions and sowing of them by farmers will be associated with less risk.

Published: December 2023

Natural CO2 springs (mofettes) represent extreme ecosystems with severe exhalations of ambient temperature geological CO2, inducing long-term soil hypoxia. In this paper an overview of mofette research in the fields of microbial ecology and biodiversity in presented, with a focus on the studies describing the impact of the changed soil gas regime on communities of arbuscular mycorrhizal fungi, archaea and bacteria. Along with the fast development of new, high-throughput molecular techniques driving the field of molecular ecology, mofettes enable new insights into the importance of the abiotic environmental factors in regulating soil biodiversity, and the community structure of these functionally important microbial groups.
Influence of arbuscular mycorrhiza on osmotic adjustment compounds and antioxidant enzyme activity in nodules of salt-stressed soybean (Glycine max)
Authors: YOUNESI Omid , MORADI Ali , NAMDARI Amin 
Published: December 2023

The influence of the colonization with arbuscular mycorrhizal (AM) fungus, Glomus mosseae (Nicolson and Gerdemann), on characteristics of growth, osmotic adjustment compounds and activity of antioxidant enzymes in nodules of salt-stressed soybean (Glycine max (L.) Merr.) was studied in this experiment. The pot experiment was arranged as a factorial in randomized complete block design with four replications at greenhouse of College of Agriculture, Tehran University, Iran. Results indicated that the contents of glycine betaine and proline in nodules were higher in inoculated than in non-inoculated plants. AM fungal colonization increased the activities of superoxide dismutase, catalase, and peroxidase in the nodules. The results indicate that the AM fungus is capable of alleviating the damage caused by salt stress on symbiotic nitrogen fixation of soybean plants by increasing the accumulation of compatible osmolytes and by increased antioxidant enzyme activity. Consequently, arbuscular mycorrhiza formation highly enhanced the salinity tolerance of soybean plant, which increased symbiotic nitrogen fixation and promoted plant growth.

Published: December 2023

Mature seeds of two traditional rice genotypes (Kalijira and Chinigura) were used for callus induction and plant regeneration on different concentrations and combinations of plant growth regulators cultured on MS (Murashige and Skoog) basal medium. Callus induction frequency was different between the cultivars, as well as among the 2,4-dichlorophenoxyacetic acid (2,4-D) levels tested. Both tested cultivars exhibited highest callus frequency at 2 mgl-1 2,4-D. The incorporation of benzylaminopurine (BAP) and kinetin (KIN) in the callus induction medium supplemented with 2 mgl-1 2,4-D did not significantly improve the callus induction frequency but required days of callus initiation were decreased compared to single use of 2,4-D. After two subcultures, at 21 days interval, embryogenic callus was placed on medium containing different concentration and combination of auxin and cytokinin. Treatment T4 (0.5 mg l-1 BAP and 0.1 mg l-1 IBA) showed the highest shoot induction: 91.67% in Kalijira and 83.33% in Chinigura. Similarly, the highest range of shoot number was also observed in both genotypes when treated with 0.5 mgl-1 BAP and 0.1 mgl-1 IBA. Plant regeneration efficiency was further observed best when treated with 1 mgl-1 2,4-D along with 1 mgl-1 2,4-D along with 1 mgl-1 BAP and 1 mgl-1 IBA. Furthermore, the highest number of callus derived shoot per culture was achieved in 2 mgl-1 2,4-D along with 1 mgl-1 BAP and 1 mgl-1 IBA. Both rice genotypes are promising in terms of callus induction frequency and morphology, and regeneration ability of the embryogenic callus.
