‘HoneySweet’ is an RNAi based genetically engineered plum resistant to Plum pox virus (PPV). Field trials in different European PPV endemic countries clearly demonstrated that ‘HoneySweet’ plum shows a highly effective and durable resistance to PPV infection. No safety concerns were found by regulatory authorities in the U.S. Expanded studies to assess the agronomic performance of ‘HoneySweet’ plum were performed under PPV endemic and ecological conditions of Northern Romania. An experimental plot including transgenic plum, ‘HoneySweet’, and two conventional plum cultivars, ‘Reine Claude d’Althan’ and ‘Stanley’, was established in spring of 2013. Agronomic performance data collected during 2016-2018 revealed a higher yield potential for transgenic ’HoneySweet’ compared to ‘Reine Claude d’Althan’ and a similarity with ’Stanley’. Average fruit weight highlighted the superior attributes of transgenic ‘HoneySweet’ compared with the two conventional plum cultivars. ‘HoneySweet’ transgenic plum fruits were larger, had lower stone/fruit ratio, and more optimal shape and colour relative to ‘Reine Claude d’Althan’ and ‘Stanley’, and a high level of resistance to PPV infection. These data and observations revealed that ‘HoneySweet’ transgenic plum has good productivity and market potential and is well adapted to PPV endemic and ecological conditions of the Northern Romania.
“HoneySweet”是一种基于RNAi的基因工程李子，对李子痘病毒(PPV)具有抗性。在不同的欧洲PPV流行国家进行的田间试验清楚地表明，“HoneySweet”李子对PPV感染表现出高度有效和持久的抗性。美国监管机构没有发现安全问题，在罗马尼亚北部PPV流行和生态条件下进行了扩大研究，以评估“HoneySweet”李子的农艺性能。2013年春天，我们建立了一个试验田，包括转基因李子‘HoneySweet’和两个传统的李子品种‘Reine Claude d’althan’和‘Stanley’。2016-2018年期间收集的农艺性能数据显示，与“Reine Claude d’althan”相比，转基因“HoneySweet”的产量潜力更高，与“Stanley”相似。平均单果重突出了转基因“HoneySweet”与两个传统李品种相比的优越属性。“HoneySweet”转基因梅子果实比“Reine Claude d’althan”和“Stanley”更大，核/果比更低，形状和颜色更优，对PPV感染具有较高的抗性。这些数据和观察结果表明，“HoneySweet”转基因李具有良好的生产力和市场潜力，并且很好地适应了罗马尼亚北部PPV的流行和生态条件。

Successful plum production requires cultivars well adapted to the specific growing conditions in the area of production. Due to the interaction between environment and genotype, it is very important to evaluate the agronomical and pomological performance of all newly introduced cultivars. The current study aimed to describe the performance of five Romanian cultivars introduced in the agroenvironmental conditions of Plovdiv, Bulgaria. ‘Pitestean’, ‘Roman’, ‘Romanta’, ‘Carpatin’ and ‘Tita’ were planted in 2013 in a collection orchard at the Fruit Growing Institute and their phenological stages flow, spring frost resistance, fruit quality and trees productivity were studied for the period 2016-2021. ‘Pitestean’ was the latest flowering cultivar. In the region, its full flowering phenophase (BBCH 65) occurred 26 days after Stanley. The most severe frost damages in 2019 and 2020 were recorded for ‘Roman’ 42% and 96%, respectively. In these two years, ‘Tita’ showed a very good spring frost resistance and its percentage of damaged flowers was lower than the damages recorded for the standard. ‘Romanta’ provided very high productivity. ‘Tita’ and ‘Pitestean’ cvs. provide qualitative large fruits and an excellent productivity in the environmental conditions of the Plovdiv region. Taking into account the combination of important for the fruit producers characteristics ‘Tita’, ‘Romanta’ and ‘Pitestean’ are suitable for expanding and diversifying the list of cultivars grown. These cultivars could be recommended for introduction in the Bulgarian plum production orchards.

The use of selected yeasts for winemaking has clear advantages over traditional spontaneous fermentation. The selection of wine yeasts is usually carried out within the Saccharomyces cerevisiae species. Yeast strains produce different amounts of secondary compounds that impart specific characteristics to the wines. This suggests that it is necessary to isolate naturally occurring autochthons strains, which exhibit a metabolic profile that corresponds to each wine. The variability, the degree of adaptation as well as the widespread of yeasts in different biotypes enable the isolation of new yeast strains with properties that can influence the fermentative processes, for this reason, the activity of isolating and selecting yeasts strains from the vintage microbiota of Trifeshti vineyard imposed as a necessity in the research and production activity. To be used in the current biotechnological practice, the Saccharomyces cerevisiae CNMN-Y-34, Saccharomyces cerevisiae CNMN-Y-35, Saccharomyces cerevisiae CNMN-Y-36, and Saccharomyces cerevisiae CNMN-Y-37 yeast strains, isolated from the indigenous flora, were tested at the industrial level. The monitoring of the alcoholic fermentation involved the registration of the commencement time and the duration of the fermentation stages, as well as the dynamical evolution of the temperature, the sugar concentration, the alcohol content, and the total acidity. The new yeast strains were assessed as valuable biological material, recommendable in vine-growing practice, as they contribute to obtaining high quality wines that reflect the personality and potential of the cultivars specific to Trifeshti vineyard.

The theme approached in this study is part of the state-of-the-art concerns regarding the valorization of by-products that represent a problem for the environment, due to the constant production and limited exploitation. The purpose of this paper was to render useful marine and wine by-products, in order to obtain fertilizers with applicability in the cultivation of the grapevine (Vitis vinifera L.). Green algae, brown algae, shells, fermented pomace, unfermented pomace and vine canes were combined in different proportions and applied to an experimental lot in the Murfatlar wine center, cultivated with the red wine cultivar, 'Feteasca neagra'. The high content in mineral elements of these by-products has led to significant increases in soil quality, especially regarding essential nutrients (phosphorus and mobile potassium) and organic matter (humus). Improvements have also been observed in the accumulation of biochemical compounds involved in plant growth and development, but also the quality and production of grapes. The obtained results encourage us to apply these fertilizers in the following years, diversifying the vine cultivars for white and red wines.

Climatic factors of the ecosystem directly influence the vegetative development of the grapevine, the production obtained, and its quality. Obtaining new genotypes with high ecological plasticity, superior yield and quality, and biological resistance can be achieved by continuously improving the existing assortment of grapevine cultivars. The crossbred of the valuable genitors and the selection of perspective genotypes is a permanent concern of horticultural researchers, in order to satisfy the consumer increasingly selective requirements. The purpose of the current study was to evaluate the adaptation of a new wine hybrid elite ('H.E. 13.1.6') obtained at Research and Development Station for Viticulture and Oenology Iasi to the environmental conditions of the Copou-Iasi viticultural centre (NE of Romania), based on agrobiological and technological observations, and analysis on grape yield and wine quality. The hybrid elite showed high productions (up to 19 t/ha), with significant accumulations of sugars in grapes (>200 g/L) and high resistance to cryptogamic diseases, indicating a good adaptation to the environmental factors of the growing area.

Sweet cherry (Prunus avium L.) is one of the most commercially important Prunus fruit tree species grown in Bulgaria. The current study aimed to describe the fruit quality of the Bulgarian bicolor sweet cherry cultivar ‘Rozalina’. The study was conducted in 2021 and ‘Van’ and ‘Pobeda Krimska’ were used for comparison. The phenological stages flow, fruit biometric data, colorimetric analyses, fruit flesh firmness, and sensory evaluation of the studied cultivars are presented. Phenological observations show that the development of all three cultivars begins in early March. The ‘Rozalina’ cv. was the first to reach full maturity/04.06/, followed by ‘Pobeda Krimska’ /10.06/ and ‘Van’ /14.06/. Under the influence of late spring frost ‘Rozalina’ showed the lowest percentage of injured flowers. From the performed biometric measurements, it was established that the standard cultivar ‘Van’ surpasses the other two cultivars in fruit height, width, thickness, and fruit weight but ‘Rozalina’ had a better stone relative share. The Bulgarian cultivar had the highest TSS (°Brix) content and fruit flesh firmness and its fruits were highly evaluated after sensory analyses.
