Influence of crop load on yield and grape quality of cv. `Chardonnay`
Authors: ČUŠ Franc 
Published: December 2023

In the research we tried to define proper crop load for cv. `Chardonnay` (Vitis vinifera L. cv. `Chardonnay`) trained on the 1.7 m high cordon trellis in the Vipava Valley. The experiment was designed as a block trial. Three levels of crop load were employed and inspected for their influence on yield and grape quality: normal crop load with 20-30 buds per vine, lower crop load with 20 buds and higher crop load than normal with 40 buds per vine. Bearing wood at the normal and higher than normal crop load was canes with 8-10 buds per cane and at the lower crop load longer spurs with 4-5 buds per spur. The lower crop load resulted in lower yield/vine together with higher must sugar content, its lower acids content and higher pruning weight. The extent of differences was strictly dependent on the climatic conditions in each year of the experiment. The normal crop load showed its great variability in the research results. The grape quality was quite high in all three treatments. Satisfactory must sugar content was obtained with the normal or even higher crop load. The proposed number of buds at winter pruning is approximately 40-45 buds/kg of pruning weight. Normal Ravaz index for defined conditions is between 7-10. In spite of the fact that the weather conditions in each year of the experiment appear to have had the strongest impact on the must acids content, the problem of its additional decrease should be taken into consideration when the lower crop load is applied.
occurence of some pests and diseases on horse chestnut, plane tree and Indian bean tree in urban areas of Slovenia
Authors: MILEVOJ Lea 
Published: December 2023

The occurrence of some pests and diseases was monitored on horse chestnut (Aesculus hippocastanum), red horse chestnut (Aesculus x carnea), plane tree (Platanus hybrida) and Indian bean tree (Catalpa bignonioides) in the period 1995-2003. The following organisms were the most common: the horse chestnut leaf-miner (Cameraria ohridella) on horse chestnut and, in recent two years, also on red horse chestnut, the Sycamore lace bug (Corythuca ciliata) and the leaf miner (Phyllonorycter platani) on plane tree. The flatid planthopper (Metcalpha pruinosa) was found inland, in Ljubljana in 2003 on A. x carnea near a busy petrol station, and on C. bignonioides in the vicinity of a motorway intersection. Along with M. pruinosa, two new parasite fungi for Slovenia were found in 2003 Erysiphe flexuosa on A. x carnea, A. hippocastanum and Erysiphe elevata on C. bignonioides.
Vpliv bakrovih spojin na aktivnost polifenol oksidaz v listih, vršičkih in grozdju vinske trte sorte 'Merlot' (Vitis vinifera L.)

Published: December 2023

Polifenol oksidaze (PPO) so metaloproteini, saj sta v molekuli vezana dva bakrova iona. Raziskovali smo vpliv bakrovih spojin, kot še vedno nenadomestljive v vinogradništvu na aktivnost PPO pri vinski trti (Vitis vinifera L.) sorte 'Merlot' v vinorodnem okolišu Goriška brda v letu 2003. Za boljše razumevanje odziva trte na količine bakrovih spojin smo priredili tri obravnavanja, in sicer: obravnavanje z enkratno (IPG), večkratno (BB) aplikacijo in (K) brez uporabe bakrovih spojin. Aktivnost PPO v listih se v času rastne dobe spreminja, saj smo največjo aktivnost PPO v listih in vršičkih določili v fenofazi 'jagode velikosti graha', najmanjšo pa v času zorenja grozdja oziroma ob trgatvi. Pri foliarni uporabi bakrovih spojin se povprečna aktivnost PPO v nezrelem grozdju statistično ne razlikuje od K, zato sklepamo, da ob dani fenofazi bakrove spojine ne vplivajo na aktivnost PPO. V nadaljevanju zorenja grozdja, v času tehnološke zrelosti grozdja se aktivnost PPO v grozdju zmanjšuje. V polni zrelosti grozdja smo določili manjšo povprečno aktivnost kateholaze in večjo povprečno aktivnost kresolaze. Kljub še vedno nejasni vlogi PPO v rastlinah, je bila pri uporabi bakrovih spojin v listih trte, pa tudi grozdju, glede na kontrolo aktivnost PPO nekoliko večja, ampak statistično neznačilna.

Published: December 2023

We studied the natural lactic bacteria population of an artisanal Italian cheese, Toma piemontese POD, from Piedmont (Northwest Italy), in order to select new strains to be used as starters in large-scale production. Isolates collected from curd and ripened artisanal cheeses were identified by the combined use of PCR 16S-23S rDNA spacer analysis, species-specific probes and 16S rDNA sequencing. Lactococci constitued 67% of the coccal isolates. Enterococci were also isolated together with strains of Streptococcus macedonicus and S. thermophilus. Lactobacilli were only detected in three samples of curds. Acidification and proteolytic activity and aroma production were also determined for each isolate. On the basis of the results a few isolates were selected and used as starters in cheesemaking trials with both raw and pasteurised milk. The produced cheeses were sensory evaluated and two of them showed typical Toma piemontese taste and flavour. The results suggest the possibility to use these new starters in both dairy industry and artisanal cheesemaking to improve product quality.
Induction of Hsp104 by Cr(VI) in yeast Candida intermedia
Authors: JAMNIK Polona , RASPOR Peter 
Published: December 2023

The synthesis of a polypeptide family named heat shock or stress proteins is one of the most conserved mechanisms of cellular protection in the case of changes in the environment. Among them Hsp104 is important, because it promotes survival of cells under extreme stresses such as high temperatures, severe oxidative damage and high concentrations of ethanol. The aim of our research was to investigate whether Hsp104 is induced in the yeast Candida intermedia exposed to Cr(VI). Namely, Cr(VI) belongs to redox active metals, which play an important role in the generation of reactive oxygen species in the cell and therefore they can lead to oxidative damages. Yeast cells were treated with Cr(VI) in the mid-exponential phase and after a defined time of incubation, Hsp104 induction was investigated by using Western blotting. Results showed that cultivation of yeast cells in the presence of 100 mM Cr(VI) caused induction of Hsp104, which is connected to formation of protein aggregates. Hsp104 assists their resolubilization and so contributes to cell survival. Its synthesis was detected 0.5 h after Cr(VI) addition and was later for up to 2 h more apparent. Therefore, we showed that Hsp104 plays an important role in the stress response of yeast Candida intermedia to Cr(VI).

Published: December 2023

The influence of different climatic conditions on fruit yield and quality of 10 determinate tomato cultivars (Lycopersicum esculentum Mill.) was studied. The experiments were conducted in the mediteranean and central regions of Slovenia. The plants were grown on an open field in the Dragonja valley and Ljubljana and in a low tunnel in Ljubljana. Data indicated that the marketable yield was significantly higher in the Dragonja valley than in Ljubljana. The average yield per plant grown in the Dragonja valley was 3.02 kg, grown on the field in Ljubljana 0.6 kg and in the low tunnel 1.0 kg. The highest marketable yield among the salad tomatoes was obtained with ‘Stormy F1’ (4.05 kg per plant) and among the processing tomatoes with ‘Hypeel 108 F1’ (4.7 kg per plant) and ‘Centurion F1’(4.1 kg per plant). Those cultivars had some good quality characteristics, important for their application (firmness, redness of skin, thickness of pericarp and succulence). Our research documented a significant yield enhancement of determinate tomato in low tunnel production for the central part of Slovenia.
Detection of the reporter and selection genes in transformed hop (Humulus lupulus L.)
Authors: ŠKOF Suzana , LUTHAR Zlata 
Published: December 2023

Agrobacterium-mediated transformation of hop nodal explants with meristems was used for the introduction of a gus reporter gene and nptII plant selection gene into Slovenian hop cv. Aurora. Emerging hop regenerants were previously tested for the gus gene expression by histochemical analysis of β-glucoronidase (GUS) activity. Approximately six months after the transformation procedure, PCR molecular analysis of shoots originating from previously GUS positive regenerants was performed to check integration of the reporter and selection genes into the hop genome. We also compared whether there were any differences in transgene integration in relation to the intensity of gus gene expression (intensive blue coloration on a larger proportion of the leaf surface or just a few blue spots) revealed by GUS-assay. In both cases, the majority of shoots had both transgenes integrated (47.7 or 55.3%) and in smaller number of shoots both transgenes were missing (38.6 or 18.8%). The fewest shoots analyzed showed just gus (2.3 or 8.9%) and slightly more nptII (11.4 or 17.0%) gene presence.

Published: December 2023

Analizirali smo krmljenje 27 krav molznic s suho mleto krmno mešanico v molzišču in poskušali ugotoviti ali prekratek čas za zaužitje povzroči stres, ki se odraža tudi s povečanim srčnim utripom (SU). Poprečna količina zaužite krmne mešanice pri eni molži je znašala 2,14 kg, krave pa so dobivale od 1 do 5 kg. Hitrost zaužitja suhe krmne mešanice je bila 249,7 g min–1. Pri večerni molži so imele krave večji SU (83,4 min–1) kot pri jutranji (81,2 min–1). Drugi mesec po telitvi je bil SU (85,10 min–1) večji kot prvi (81,04 min–1) in tretji mesec po telitvi (80,79 min–1). Ugotovljeno je bilo, da do količine 3 kg krmne mešanice na molžo ni prihajalo do povečanega SU. Z naraščajočo količino krmne mešanice nad 3 kg je naraščal tudi SU. Pri kravah, ki so dobile največ krmne mešanice, se je SU najbolj pospešil proti koncu molže. Velika količina suhe krmne mešanice, ki je visoko proizvodne krave molznice v molzišču ne morejo požreti v kratkem času molže povzroči pri njih stres.
Odziv kmetijskih rastlin na UV-B sevanje
Authors: GERM Mateja 
Published: December 2023

UV-B sevanje vpliva na strukturo in anatomijo lista, fotosintezna barvila, UV-B absorbirajoče snovi, fotosintezo, rast, razvoj in produkcijo. V naravi so rastline izpostavljene tudi drugim okoljskim dejavnikom, ki imajo na rastline skupaj z UV-B sevanjem sinergističen ali antagonističen vpliv. Večina raziskav o vplivu UV-B sevanja je bila kratkotrajnih, narejenih v nadzorovanih razmerah v laboratorijih, rastlinjakih in rastnih komorah, kjer je bilo UV-B sevanje zelo močno, UV-A sevanje in PAR pa prešibko. Rastline so bolj občutljive na UV sevanje, če je vidna svetloba (PAR) zmanjšana. Klimatske spremembe bodo vplivale na produktivnost kulturnih rastlin, ki so zaradi procesov žlahtnjenja mnogokrat še občutljivejše na spremembe v okolju.

Authors: ŽNIDARČIČ Dragan , VIDRIH Rajko , GERM Mateja , BAN Dean , TRDAN Stanislav 
Published: December 2023

The impact of water-soluble carbohydrate composition in relation to damage levels of onion thrips (Thrips tabaci Lindeman), were studied under field conditions at the Experimental Field of the Biotechnical Faculty in Ljubljana on 7 cabbage cultivar (Brassica oleracea L. var. capitata). Onion thrips showed weak preference on cabbage heads with high amount of total carbohydrate, fructose and glucose and higher preference on heads with high concentration of sucrose. While amount of total carbohydrate, fructose and glucose were negatively correlated with damage levels (r2 = -0.7667; r2 = -0.6947; r2 = -0.8263), sucrose amount was not. There was a strong positively relationship between sucrose amount and the level of plants infested (r2 = +0.7378). The cv.‘Hinova’, which had the highest amount of total carbohydrate, showed itself to be the most resistant to the onion thrips.
Prevalence of coagulase positive pathogenic Staphylococcus aureus in milk and milk products collected from unorganized sector of Agra
Authors: SINGH Priyanka , PRAKASH Alka 
Published: December 2023

The present study deals with the sampling, isolation and biochemical characterization of Staphylococcus aureus from raw milk of cow and buffalo, and milk products (khoa sweets and cottage cheese) collected from different unorganized sectors of Agra city, India. Samples of raw milk from cow, cottage cheese and khoa sweets indicated that S.aureus contamination was higher in east of Agra (Ram Bagh), whereas samples of raw milk from buffalo, collected from the west of Agra (Sikandra), showed higher S.aureus contamination. Least contamination was observed in samples of khoa sweets and cottage cheese collected from west of Agra (Sikandra) and in samples of cow and buffalo milk collected from North of Agra (Dayalbagh) and east of Agra (Ram Bagh), respectively. The incidence of high contamination in raw milk and milk products suggests that protective measures are inadequate and need to be enforced to avoid potential threat to public health.
Antibiotic-resistant soil bacteria in high-altitude (5000–6000 m) soils of the Himalaya
Authors: STRES Blaž 
Published: December 2023

In this study, low-carbon soils collected from an altitude transect from 5000 m to 6000 m were adopted as a simple model system with lower interaction complexity. This could help disentangle the basic environmental factors shaping the abundance and distribution of expressed resistance traits in culturable portion of fast growing heterotrophic strains. Improved plate counts were performed at 4 °C using 0.01 diluted nutrient broth supplemented with cold soil extract as a general media and additionally supplemented with antibiotics Ampicillin, Erythromycin, Kanamycin and Tetracyclin. A number of colonies (500) isolated from six locations were also tested separately for their antibiotic resistance. The results show that these high-altitude cold soils contained bacterial populations culturable at 4 °C in the range of 106 cells / g that were resistant to the four antibiotics and their various combinations tested in this study. The highest prevalence of resistance was observed in vegetated soils, whereas almost two orders of magnitude lower abundance of resistant cells was cultured from barren soils. Redundancy analysis showed that vegetation, soil carbon and pH were successful in explaining the interaction between environmental parameters and various culturable fractions of cold soil bacteria used in this study.
Economic growth and trend changes in wildlife hunting
Authors: KAWATA Yukichika 
Published: December 2023

Petty-Clark’s law suggests that as the economy of a country develops, its proportion of primary industries declines while those of its secondary and tertiary industries increase. Traditionally, hunting has played a crucial role in a country’s food supply; however, currently, it is increasingly viewed as a leisure activity. This paper empirically examines whether Petty-Clark’s law holds in case of hunting in European countries. The results reveal that the proportion of hunters across countries increases when the per capita GDP is between 5,000 and 15,000 USD. Once the per capita GDP crosses the 15,000 USD mark, two major trends are detected: the number of hunters continues to increase in some countries but decreases in some other countries. Finally, the number of hunters in a country stabilizes when its per capita GDP reaches around 25,000 to 30,000 USD.
Topics related to social sciences by authors from Slovenia in agriculture-and-life-sciences database CAB Abstracts
Authors: BARTOL Tomaž , HOČEVAR Marjan 
Published: December 2023

Documents related to social sciences are processed/indexed by several field-specific (e.g. Sociological Abstracts) and general (Web of Science, Scopus) bibliographic databases. These topics are scattered also among other specialized databases and information systems in agriculture, biomedicine, and other life-sciences, for example Agris, Agricola, FSTA, Medline (PubMed), etc. Agriculture can also involve social issues such as rural sociology, public services, settlements, demography, tourism (agritourism). Relevant documents may thus elude attention of researchers which seek information in a limited number of databases. We used CAB Abstracts (CABI/CAB International), the leading global database for agriculture, environment, veterinary sciences, applied economics, food science and nutrition. In a bibliometric/scientometric analysis, we used the classification based on subject categories CABICODES (CC), which enable identification of general research subject areas, in order to assess publishing patterns by researchers from Slovenia in 1991-2010. We assessed growth, and identified database records which had been classified with the social-sciences-related CC. We assessed co-classification or co-occurrence of these categories with other general subjects, such as Economics, Plant Science and Protection, Food Science and Produce, Animal Science, Forestry and Wood, Pathogen, Pest, Parasite and Weed Management, Soil Science, Human Health and Nutrition, Education, Extension, Information, Training, Natural Resources. 336 records were published by Slovenian authors, and classified with social sciences CC in CAB Abstracts. In total, 1313 different CC had been assigned to the records. The social-sciences-related research co-occurs with the following subject matter, in a decreasing order: economics, forestry/wood science, natural resources (e.g. water, meteorology, pollution), human biology/health/nutrition, food, plant, animal science/protection.

Authors: BAVČAR Dejan , BAŠA ČESNIK Helena 
Published: December 2023

Wine aroma is influenced by a number of volatile compounds. This article describes the validation of the method for 26 volatile compounds found in wine. Volatile compounds were determined with discontinuous liquid-liquid extraction and GC-MS detection. It was determined, that the method is linear with square correlation coefficient ranging from 0.961 to 0.999. Limits of quantitative determination range from 0.52 mg/L to 14.8 mg/L. Recoveries range from 71.1% to 105.7% except for two compounds with lower recoveries. Measurement uncertainty ranges from 5.0% to 28.9%. According to the validation, the method is suitable for the determination of at least 24 volatile compounds common to wine. A practical method application was presented on Zelen wine variety from two different production procedures.

Published: December 2023

Za 18 meteoroloških postaj na širšem območju Triglavskega narodnega parka smo za obdobje 1961-2009 analizirali letne višine padavin, število dni z dnevno višino padavin nad 5, 10, 20, 50, 100 in 150 mm ter število dvodnevnih nalivov z višino padavin nad 50, 100 in 150 mm. Za snežno odejo smo analizirali število dni po letnih časih in za snežno sezono ter trende v številu dni s snežno odejo. Največ padavin je imela v letnem povprečju Žaga pri Bovcu (2972 mm), najmanj Rateče (1532 mm). Medletna variabilnost višine padavin je na vseh postajah velika, v izrazito mokrih letih je višina padavin več kot dvakratna višina tiste v najbolj sušnih letih. Povprečne letne višine padavin, izračunane za dekade, se statistično značilno razlikujejo. Na večini postaj je bila najbolj mokra dekada 1961-1969, najbolj sušni dekadi pa 1980-1989 in 2000-2009. Na vseh postajah se pojavljajo močni enodnevni in dvodnevni nalivi, variabilnost števila izjemnih padavinskih dogodkov se povečuje z višino padavin. Največje število dni z višino padavin >5 mm ima Vogel (90), >10 mm in >20 mm Kneške Ravne (69 oz. 44). Dvodnevnih nalivov >50, >100 in >150 mm je največ na Žagi, najmanj pa v Ratečah. Na vseh postajah lahko vsako leto pričakujemo vsaj en dan, ko višina padavin presega 150 mm. Dolžina snežne sezone se v zadnjih letih zmanjšuje. Trend v številu dni s snežno odejo je na vseh postajah negativen. Velikost statistično značilnih sprememb je od -4,3 dni/10 let na Žagi do -14,9 dni/10 let v Stari Fužini.

Using a different growth medium greatly improves distinction of Butyrivibrio fibrisolvens and Pseudobutyrivibrio xylanivorans strains by the cellular fatty acids and aldehydes profiles
Authors: ZOREC Maša , VODOVNIK Maša , MARINŠEK LOGAR Romana 
Published: December 2023

A total of 11 ruminal strains currently assigned to Butyrivibrio fibrisolvens and Pseudobutyrivibrio xylanivorans were cultivated in two different media, rumen fluid containing M2 and short-chain fatty acid (SCFA) containing M330, and their cellular fatty acid methyl esters (FAME) and dimethylacetals (DMA) were analyzed using gas chromatography. A comparison of the FAME/DMA compositions revealed that the difference in SCFA contents in the growth medium induced a pronounced quantitative effect on the cellular branched-chain fatty acid and aldehydes proportions only in the P. xylanivorans strains. This study shows that FAME/DMA analysis is a powerful chemotaxonomic tool in the group of phenotypically similar rumen butyrivibria especially when the influence of the growth medium is evaluated.

Published: December 2023

The aim of the study was to estimate some effects on mortality and growth in rabbits. The study was carried out in Slovenian SIKA sire line. In total, 1028 kits of 80 does were included. In the analyses the effects of parity, number of liveborn kits, number of teats, and season of kits birth were analysed. Birth weight was included in the model for mortality, while age was included in the model for growth. Parity, litter size, teat number and season affected the body weights. Body weight varied also according to age. Mortality has changes by litter size, season and initial weight. An average litter size was 8.77 kits born, 8.15 kits born alive and 7.00 kits weaned. The birth to weaning mortality was 14.4% and mortality has steadily declined with age. Average weight up to age 3 days was 72 g and at weaning 959 g. Kits in smaller litters and kits from does with more teats had a higher growth rate. Also kits grow faster in the colder months.
