This paper presents the results of the testing during the winemaking process using commercial active dry yeasts (CADY) in parallel with yeast biomass produced starting from yeasts isolated from Pietroasa area (Romania) (PAY). PAYs were obtained based on autochthonous yeasts isolated from Busuioacă de Bohotin (BB) and Tămâioasa Românească (TR) grape varieties. Two variants of must for each grape variety were taken in study, i.e. obtained from early harvested grapes (TRD and BBD) and from late harvested grapes (TRS and BBS). Winemaking experiments were carried out with 7 types of commercial yeasts and two types of commercial nutrients. The alcoholic concentration of the experimental wines varied from 11.8 % for WTRD to 18.4% for WBBD. The WBBD & S samples showed a higher average trans-resveratrol content (1.716 and 1.555 mg/L, respectively) compared to the WTRD & S wine samples (0.590 and 1.365 mg/L, respectively). The variation in the cis-resveratrol content between the experimental variants produced with PAY was not significant.
本文介绍了在葡萄酒酿造过程中使用商业活性干酵母(CADY)和从罗马尼亚Pietroasa地区(PAY)分离的酵母开始生产的酵母生物量的测试结果。从busuioacei de Bohotin (BB)和t mioasa romas neascei (TR)葡萄品种中分离到的本地酵母中获得了pay。在研究中，每个葡萄品种都采用了两种不同的must，即从早期收获的葡萄(TRD和BBD)和从晚期收获的葡萄(TRS和BBS)中获得。采用7种商品酵母和2种商品营养剂进行了酿酒试验。实验酒的酒精浓度从WTRD的11.8%到WBBD的18.4%不等。WBBD和S样品的反式白藜芦醇平均含量分别为1.716和1.555 mg/L，高于WTRD和S样品的0.590和1.365 mg/L。不同品种间顺式白藜芦醇含量差异不显著。

Soil salinity is one of the most critical environmental stressors that reduces crop yields worldwide and affects wild plants distribution in nature. Climate change is increasing the salinity of irrigated cropland and natural saline habitats of high ecological value, highlighting the interest in elucidating salt stress tolerance mechanisms in crops and wild plants. One of the well-known adverse effects of salt is the interference of toxic Na+ ions with K+ uptake and homeostasis, as both cations compete for the same binding sites and transport proteins. Therefore, an increase in substrate salinity is usually accompanied by a reduction of K+ concentrations in the plant organs, as it has been observed in many species, both salt sensitive and tolerant. However, in other plants, K+ contents are maintained or even increase with increasing Na+ concentrations; for example, in some species, K+transport to the leaves is activated at high external salinity to counteract the toxic Na+ effects. This review will present several examples of these mechanisms and their relevance for stress tolerance, based primarily on our group's work during the last 20 years.

Two aquatic plant species were subjected to this study: Hydrocharis laevigata synonym Limnobium laevigatum (Alismatales: Hydrocharitaceae) and Lagenandra meeboldii (Alismatales: Araceae). The paper presents first insight into the microscopic aspects of cross-sections made through root, petiole and leaves of in-vitro plant L. laevigatum and Lagenandra meeboldii ‘Red’ form, biological material purchased from the Romanian market of ornamental aquarium plants. Considering the invasive potential of South American spongeplant, already well documented for other European countries, this short survey draws attention to the danger represented by releasing decorative aquatic plants from aquarium as a factor involved in a possible future spreading of this species into natural environments.

The paper aimed to analyze the effect of the application of organic fertilizer biohumus on the content of heavy metals in the soil and spring barley plants in the Donetsk industrial region of Ukraine. Application of biohumus in the organomineral nutrition system led to decrease the content of mobile forms of copper, zinc, lead, cadmium by 17.1%, 23.4%, 22.6% and 23.1% respectively. The content of copper and zinc in the grain was almost at the control level, the accumulation level of lead and cadmium in the spring barley grain decreased by 1.6 and 1.4 times, respectively. The variant of the organo-mineral nutrition system with foliar treatment of plants with biostimulant regoplant allows to reduce the amount of traditional mineral fertilizers by up to 50% while maintaining the yield level, to reduce the coefficients of biological absorption of lead and cadmium by 1.4 times compared to the control. To reduce the risk of soil and grain contamination by heavy metals in industrial regions, it is advisable to use an organo-mineral fertilizer system.

This article is devoted to the study of the systematic, biomorphological, and ecological classifications of the dendroflora of eleven park-monuments of landscape art established in the second half of the 20th century in the Ukrainian Polissya. In the protected parks, we identified 193 taxa of woody plants that belong to 82 genera and 34 families. The most common one was the family Rosaceae Juss. Among encountered woody plants, 14.2% species were indigenous and occurred in 5-11 parks. Fifty-nine woody plant species, among which 64.4% were rare, were associated with a single park and were represented by 1-7 specimens. At the same time, 69 woody plant species were associated with 2-4 parks, with 40.4% rare and 17.4% indigenous plant species. Life forms were represented by phanerophytes (36, 63, and 76 species of megaphanerophytes, mesophanerophytes, and micro- and nanophanerophytes, respectively) and a chamaephyte. In turn, the ecological structure was dominated by mesophytes (39.8%), hemisciophytes (46.6%), and mesotrophs (51.7%). Except for Bairak PMLA and Novostavskyi dendropark, the dendroflora of the surveyed parks was diverse.

Salvia officinalis L. (sage) and Melissa officinalis L. (lemon balm) are two valuable medicinal plants from Lamiaceae family. Considering the therapeutic potential of sage and lemon balm extracts, there is currently great interest to increase the production of biological material and the synthesis of bioactive compounds by different methods. Both micropropagation and gamma irradiation represent efficient methods of stimulating the synthesis of bioactive compounds in plants. In order to produce biological material, it is important to establish the doses of gamma radiation that do not have a phytotoxic effect on plants. The aim of the present study was to evaluate the effect of different doses of gamma irradiation (100, 300, and 500 Gy) on sage and lemon balm by quantifying of some biochemical compounds (assimilatory pigments, soluble carbohydrates, and total polyphenols) in in vitro plants. The results obtained revealed that high doses of gamma radiation have phytotoxic effect on in vitro raised plants. However, micropropagation is an efficient method to produce high quality biological material, source for obtaining extracts with therapeutic potential.

Climate change has become the biggest global challenge to agriculture and food production. In the context of current environmental changes, the aim of this study is to identify the optimal sowing season that leads to obtaining high and constant yields. The study followed the reaction of 7 native maize hybrids to cultivation in 3 different sowing seasons, over a period of 3 years. The data obtained show us that the best yield results are obtained on mid-early hybrids (9327- 9843 kg/ha). Sowing maize too early, are obtained lower yields than for maize sown at 10ºC in the soil, with a very significant difference of 1337 kg/ha. Favorable climatic conditions in 2020 and 2021 emerge from the average yields obtained in the two years, 10343 kg/ha (2020) respectively 9424 kg/ha (2021). The climatic conditions of 2022 were less favorable, summer drought having a negative effect on average maize yield, which was 6924 kg/ha.

The study used the remote sensing method (Sentinel 2) to analyze the sunflower crop and to estimate the production. The study area was within the DES, ULS 'King Mihai I' from Timisoara, Romania. Eight series of images were taken (April 06 - August 07, 2022). Based on the spectral information, the NDMI, NDVI, NPCRI and NBR indexes were calculated. Spline models best described the variation of index values in relation to time (t, days) during the study period, ε = −0.04286 for NDMI, ε = 0.01172 for NDVI, ε = 0.00537 for NPCRI, respectively ε = −0.08481 for NBR. Very strong correlations were found between NDVI and NDMI (r=0.975), between NBR and NDMI (r=0.997), and between NBR and NDVI (r=0.967), p<0.001. Strong correlation was recorded between NDVI and NPCRI (r=-0.881), p<0.01. Moderate correlations were found between NDMI and t (r=0.729), between NBR and t (r=0.752), between NPCRI and NDMI (r=-0.776), and between NBR and NPCRI (r=-0.762), p<0.05. The regression analysis facilitated the estimation of the production based on calculated indices, under conditions of statistical safety.

The conservation of agrobiodiversity begins by its characterisation to know it. On this knowledge, we must study the interactions of the different species with their abiotic and biotic context. However, as a consequence of the effects of climate change, the abiotic context is variable and extreme. Therefore, abiotic stress induced by climate change jeopardises both the biodiversity and plant genetic resources, therefore, food security. The latter is more drastic in developing communities. Thus, given the predictions of the effects of climate change at different geographical levels, it is urgent to develop strategies that might improve the management of biodiversity and promote resilience against said effects. On the one hand, preserving and describing the agrobiodiversity allows us to identify the genetic material most appropriate under different abiotic contexts. On the other hand, plants, including crops, are not isolated species and develop in a very heterogeneous biotic context that can enhance plant tolerance to abiotic stress. In this work, we review key concepts, threats, challenges, and strategies to improve agrobiodiversity management.

The objective of this study was to investigate the effect of foliar fertilization as compared to mineral fertilization on yield and yield components of soybean. The experiments were carried out during 2020 and 2021 growing seasons at Research and Development Station for Agriculture Turda (RDSA Turda), Romania, using randomised complete block design with three replications. The two variants of foliar fertilization contain macro and micro elements, being applied in different phases of soybean growth and development. Among the foliar fertilization options, T1stood out as the foliar fertilization option that contributed to some extent to the growth of plant height, the number of pods/plant, the number of grains/plant, the weight of grains/plant and yield. The second variant of foliar fertilization (T2) in most of the analysed cases determined a decrease in the yield elements as well as the yield compared to the control variant.

The second variant of foliar fertilization (T2) in most of the analysed cases determined a decrease in the yield elements as well as the yield compared to the control variant.","PeriodicalId":44979,"journal":{"name":"AgroLife Scientific Journal","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42405745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
