This paper presents the efforts carried out at Research Institute for Fruit Growing between 2020-2021, in order to assess the strawberry behaviour to the hydric and biocenotic stress to improve the water and nutrients use and to build precision driven technologies that can be transferred to the farmers. Thirteen strawberry cultivars and three promising hybrids were evaluated in the field in order to evaluate the response to the fertirrigation regime, the chlorophyll fluorescence and the photosynthetic potential. We also focus on the behavior of the cultivars to the major pest and diseases, forecasts using warning modules, and an innovative mobile application and warning algorithms elaborated on the computer, and productivity potential into the first year of fructification. The ratio between the main macro-elements N 12.5: P 18.0: K 1.0: Mg 1.5 aiming to provid a very good nutrition to the strawberry plants and preparation for the cold season. The varietal sensitivity index to diseases (VSI%) of the newly introduced cultivars, ranged between 0.48 at 'Dona' cultivar and 2.53 at 'Mira' cultivar but no more than 5.00 at 'Elsanta' cultivar. The average fruit weight ranged between 18.5 g at 'Daroyal' and 27.5 at 'Alba' cultivars. So, in this group, the productivity potential ranged between 451 to 1100 g /plant.
本文介绍了水果种植研究所在2020-2021年间所做的努力，以评估草莓对水分和生物胁迫的行为，以改善水和养分的利用，并建立可以转移给农民的精确驱动技术。对13个草莓品种和3个有潜力的杂交品种进行了田间评价，以评价其对施肥制度、叶绿素荧光和光合势的响应。我们还关注品种对主要病虫害的行为，使用预警模块进行预测，并在计算机上详细阐述了创新的移动应用程序和预警算法，以及进入结果的第一年的生产力潜力。主要常量元素N 12.5: P 18.0: K 1.0: Mg 1.5的比例旨在为草莓植株提供良好的营养，为寒冷季节做好准备。新引进品种的病害敏感指数(VSI%)在‘多娜’品种的0.48和‘米拉’品种的2.53之间，而‘埃尔桑塔’品种的VSI%不超过5.00。‘darroyal’品种的平均果实重量为18.5 g，而‘Alba’品种的平均果实重量为27.5 g。因此，在这一组中，每株植物的生产力潜力在451到1100克之间。

Lavandula angustifolia Mill. is a perennial plant, which is part of the Lamiaceae family, it is known as a medicinal and aromatic plant, however in recent years it can be found as landscaping, cut flower, or even in the art of culinary. This majestic plant propagation by seeds is a slow, hard difficult stage, for this reason, new methods are needed. Biostimulants could improve seed germination percentage and time, and also could improve productivity and growth of the plants. This study aimed at the effect of GA3 on two commercial cultivars of Lavandula angustifolia Mill. Lavender seeds were subjected to three concentrations of gibberellic acid (100, 200, 300 ppm), under controlled conditions in the growing chamber. Under our experimental conditions GA3 improved the germination percentage and time of lavender seeds. It can be concluded that biostimulators, as gibberellic acid could have an effect on dormancy breaking of Lavandula seeds.

This study investigates the Lepidoptera order representatives among the pests present in apple and plum orchards in the central and northern part of the Bistrita region. This study aimed to find out which ones of the Lepidoptera pests are present in the area and what is their population density. By field trapping of moths and leaf miners, in 2021 we are presenting an up-to-date situation of the main damaging species from the Lepidoptera order. Pheromone traps with attractants for seven species were placed in four locations in apple and plum orchards. The monitored species were: Cydia pomonella, Hedya nubiferana, Spilonota ocellana, Phyllonorycter blancardella, and Leucoptera scitella in the apple orchards. In plum orchards, we placed lures for Cydia funebrana and Grapholita molesta. Our data confirm some of the previous known facts about the flight patterns of Cydia pomonella, Phyllonorycter blancardella, Leucoptera scitella, Cydia funebrana and Grapholita molesta but show a longer flight period. Defoliators such as Hedya nubiferana and Spilonota ocellana are also present and could become a threat in the next years.

In the context of durable viticulture, the initial propagating material is primarily responsible for the health of vineyards from the virological point of view, also this having an important role in controlling the spread of virus diseases. This study analyzed the behavior of grapevine genotype infected with Grapevine fleck virus ('Regina viilor'), and grapevine genotypes infected with GFkV and Grapevine Pinot gris virus ('Pinot gris 14 Șt.', 'Merlot 146 Mn.', 'Balaban alb') when applying in vitro chemotherapy with ribavirin and oseltamivir used simultaneously, with the aim of new virus-free plants regeneration. Regarding the phytotoxic effect of antivirals, the apices and axillary buds of 'Pinot gris 14 Șt.' and 'Regina viilor' showed good tolerance to treatment, while the explants of 'Balaban alb' and 'Merlot 146 Mn.' were seriously affected, especially the axillary buds. The chemotherapy led to the effective elimination of Grapevine fleck virus in all studied grapevine genotypes, while Grapevine Pinot gris virus was eliminated in a rate of 75-100%, depending on the genotype and type of explant. The phytotoxic effect induced by antivirals, the tolerance of genotypes to certain treatment and the in vitro regenerative potential of each genotype proved to be the main factors influence the efficiency of the applied treatment and the number of virus-free plants obtained.

The aim of this study was the identification the pathogenic fungi causing the grapevine trunk diseases (GTD) in some Romanian vineyards. Twenty-one samples of biological material (bark, canes, and trunk wood) were collected from Tarnave, Aiud, Minis and Sarica Niculitel vineyards. Petri dish culture method was used to grow the fungi, inoculated at the central point on the Sabouraud medium. Fungal species were identified by macroscopic and microscopic examination based on the morphological characteristics of fungal colonies developed on medium: the type and color of mycelian hyphae, the shape, color and size of spores. In the studied Romanian vineyards GTD were caused by: Phaeoacremonium aleophilum, Phaeomoniella chlamydospora, Stereum hirsutum, Diplodia seriata, Cadophora luteo-olivacea, Diatrypaceae sp., Phomopsis viticola and Eutypa lata, being associated with diseases, such as: Esca, Petri, excoriosis and Eutypa, identified by plate culture method and microscopic examination.

More than 80 viruses are reported as causing damage to the grapevine, but some of them are rare and cause negligible damages. However, other viruses are veritable pathogens for this crop, affecting the production quantity and quality, such as: grapevine leafroll-associated virus serotype 1+3 (GLRaV-1+3), grapevine fleck virus (GFkV), and grapevine fanleaf virus (GFLV). In this study, we present the effects of Serlac V, Growspore Vita and Nutryaction biostimulants on the grapevine plants belonging to 'Valerien' and 'Italia 93 Mf.' genotypes infected with GFkV and 'Cardinal 74 Mf.' genotype infected with GLRaV-1+3 and GFkV. Determinations have been made regarding the content of assimilating pigments in leaves (chlorophyll a, chlorophyll b, and carotenoids), a diameter of the cane and of the pith, leaf surface, stomata length and ostioles opening.

Tea growing in Azerbaijan is concentrated on an area of 5.33 thousand square kilometers, located within the Lankaran and Astara districts, including the districts of Astara, Lankaran, Masally, Lerik, Yardimly and Jalilabad. About 90% of Azerbaijani tea is produced in Lankaran, near the southern border with Iran. Tea was first grown in the Caspian region of Azerbaijan in the 1880s. Due to its favorable climatic conditions, the region currently produces 99% of the Azerbaijani tea harvest. The cultivation of tea in the country is limited by soil and climatic conditions and the biological characteristics of plants. The article gives a general characteristic of tea plantations growing in the conditions of the Lankaran-Astara zone (southern part) of the Republic of Azerbaijan, which is relatively unfavorable for tea plants. The results of research on clonal breeding of tea are presented, to select new forms to increase productivity and product quality. It is noted that during seed propagation, tea bushes have a significant difference in morphological and biological characteristics. Tea plants differ in yield, the strength of shoots, quality indicators of raw materials, length of the growing season, generative activity, and other economic characteristics. The variability inherent in the tea plant can be successfully used for the selection and isolation of the forms most valuable in terms of breeding characteristics, and their further vegetative reproduction. The transfer of the tea-growing industry of the republic to a modern scientific basis by breeding and planting plantations with new high-yielding and high-quality cultivars clones will contribute to the intensification of production.

The pomegranate moth (Euzophera punicacella Mocre.) is the most widespread and well-known pest of pomegranate bushes in the western part of Azerbaijan. The loss of yield from the pomegranate moth (Euzophera punicacella Mocre.) in the pomegranate orchards of Azerbaijan often reaches significant sizes. The article provides data on the biology, prevalence, harmfulness of the pomegranate moth (Euzophera punicacella Mocre.), as well as measures to combat it. Research work was carried out from 2018 to 2020 in the pomegranate orchards of the Ganja-Kazakh geographic zone: route surveys, stationary observations, laboratory field and field experiments. Stationary observations were carried out in the industrial pomegranate orchards of the Goranboy region (western part of Azerbaijan, part of the GanjaKazakh geographic zone). Caterpillars collected from damaged fruits in a pomegranate garden served as the material for the study. To determine the harmfulness of the pomegranate moth (Euzophera punicacella Mocre.), 10 test bushes were isolated on the cultivars ‘Krmyzy kabukh’ and ‘Pink gulosha’ before flowering. The harmfulness was established by a systematic analysis of damaged fruits and removable crops from experimental bushes. The wintering place of caterpillars was determined by examining 10 experimental bushes at the age of 7 years. Starting from the third ten-day period of March, we examined weekly carrion, crusts, mummified pomegranate fruits that remain in the garden after harvesting and the bark of boles. When studying the timing of the development of individual phases, the number of generations and other issues in laboratory-field conditions, experiments were set up under gardens mounted on pomegranates. The optimal timing of chemical and biological pest control was recommended based on the study of the biological characteristics of the pomegranate moth (Euzophera punicacella Mocre.).

This paper aims to highlight the superior agrobiological and technological potential of hybrid genotypes, obtained by intraspecific hybridization of cultivars 'Victoria' x 'Black Pearl', 'Muscat de Poloskei' x 'Victoria', 'Coarnă neagră' x 'Victoria', 'Victoria' x 'Victoria'. Several genotypes resulted from the hybridization of the mentioned cultivars, which stood out through at least two characters, similar or superior to the parental cultivar were selected in the comparative field. The evaluation of agro-biological characteristics of elites was based on the following indices: percentage of fertile shoots, fertility, and productivity coefficients. Technological descriptors related to the weight of the bunches, the weight of 100 berries, the skin's weight, the seeds, the content of the wort in sugars, the content of the wort in acidity were used in the study. The Victoria cultivar was taken as a witness, being considered a reference both nationally and internationally. The selected genotypes were distinguished by large grapes, very large grains, pleasant colors, high tolerance to biotic and abiotic factors. The new perspective elites show a high percentage of buds, high fertility, medium to high, the accumulation of sugars and total acidity in the must in a favorable way for mass consumption. To present more conclusively the multitude of data obtained, through statistical-mathematical processing, the general conclusions related to the mode of manifestation of hybrid elites in interaction with biotic and abiotic factors have been formulated considering the natural variability of all processes and phenomena involved.

Several genotypes resulted from the hybridization of the mentioned cultivars, which stood out through at least two characters, similar or superior to the parental cultivar were selected in the comparative field. The evaluation of agro-biological characteristics of elites was based on the following indices: percentage of fertile shoots, fertility, and productivity coefficients. Technological descriptors related to the weight of the bunches, the weight of 100 berries, the skin's weight, the seeds, the content of the wort in sugars, the content of the wort in acidity were used in the study. The Victoria cultivar was taken as a witness, being considered a reference both nationally and internationally. The selected genotypes were distinguished by large grapes, very large grains, pleasant colors, high tolerance to biotic and abiotic factors. The new perspective elites show a high percentage of buds, high fertility, medium to high, the accumulation of sugars and total acidity in the must in a favorable way for mass consumption. To present more conclusively the multitude of data obtained, through statistical-mathematical processing, the general conclusions related to the mode of manifestation of hybrid elites in interaction with biotic and abiotic factors have been formulated considering the natural variability of all processes and phenomena involved.","PeriodicalId":52654,"journal":{"name":"Romanian Journal of Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46181656","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}
