In addition to its medicinal qualities, a high content of essential oils, as well as phenols and flavonoids, the crop is an excellent alternative to annual floral and ornamental plants in landscaping. In this regard, the purpose of the research was to evaluate seven varieties of Calendula officinalis L. in terms of duration,intensity and timing of the beginning of flowering, the activity of growth processes, size, color, inflorescence structure and the identification of the most adapted to growing conditions varieties that have high decorative qualities. Proposals were made on the directions of using the studied varieties in ornamental gardening and landscaping of the territory. The studies were carried out in 2022-2023 at the experimental site of private household plots in the central zone of the Krasnodar region. As a result of the research, it was found that the studied varieties of calendula had significant differences in a number of morpho-biometric indicators, but turned out to be highly adapted to the growing conditions in the south of the Russian Federation. According to the combination of ornamental qualities, three varieties of calendula officinalis were identified for cultivation in the central zone of the Krasnodar region. The Tutti-Frutti yellow variety is recommended for planting in flower beds due to the bright flowers of the inflorescence and the low growth of the plants. It is advisable to use the Geisha variety for the design of plots in landscape design and for cutting flowers. In garden and park landscaping, attention should be paid to the King's Cup variety, which stands out for a complex of decorative qualities and a long flowering period.

Studies in the agroecological conditions of the Krasnodar region on the southern chernozems revealed the most productive norm of loading of grape bushes with shoots for the technical varieties Kurchanskiy, Dmitriy, Vladimir, Granatovyi, Antaris and Alkor, on leached chernozems – for the table seedless variety Centennial Seedless. According to the results of electrophoretic separation of peroxidases in polyacrylamide gel and an increased content of ascorbic acid, increased frost resistance was established in the varieties Kristall, Vostorg, Krasnostop AZOS. The Vostorg and Zarif varieties proved to be more adaptive to the stresses of the summer period in terms of leaf hydration, bound water content, the ratio of chlorophylls and carotenoids, the amount of proline and water-soluble sugars, membrane permeability. The role of physiologically active substances in increasing the adaptive potential of grape plants has been established. The treatment of Merlot vines with methyl jasmonate and epibrassinolide during deep dormancy period, as well as proline, salicylic acid and epibrassinolide during induced dormancy period had a positive effect on the condition of the vine: there was a decrease in electrolyte yield. Sustainable grape cultivation is achieved with the systemic use of the «Bioconcentrate-Z» effluent by the non-root method. Against the background of nonroot treatments of Merlot and Cabernet Sauvignon varieties, a higher level of plant water supply, an increase in potassium content, green pigments, organic acids and grape yields were established. Physiologically active compounds and the preparation Turinbash have a positive effect in intensive own-root plantations of native and promising introduced grape varieties against the background of phylloxera infection in the southern part of Dagestan. The created yield forecasting method based on the NDVI of the grape plant and the actual data of multispectral images of the phenophases of flowering and growth allows to increase the accuracy of the calculated yield capacity to the actual one with a deviation from 0 to 0.8 kg per bush, the accuracy of the forecast increases by 2 times by the end of the growth phase and by the beginning of the maturation phase.

Consumers prefer tomatoes in fresh form. However, being a climacteric crop, tomatoes differ during storage and maturation by a high rate of respiration and evaporation of moisture, which leads to a decrease in valuable nutrients, deterioration in quality, over-ripening and rapid aging, which as a result reduces the marketable appearance of products. Traditional methods of processing tomatoes before storage are not always effective enough to maintain the quality of tomato fruits at the proper level, since it is not always possible to store tomatoes at the recommended low temperature, the necessary relative humidity, etc. In order to increase the storage time of tomatoes while maintaining their quality and safety, it is necessary to search for new modern methods of fruit processing before storage. In this regard, an overview of existing traditional technologies, as well as modern and promising techniques and methods for preparing fresh tomatoes for storage, contributing to the reduction of quantitative losses, preserving qualitative characteristics, is carried out. The most promising methods of preliminary preparation of tomatoes for storage, providing a high level of physical-chemical, organoleptic and microbiological indicators that ensure the safety of stored products are: treatment with ethylene biosynthesis inhibitors and ethylene absorbers, ozonation, modified gas atmosphere, electric field and ultrasound treatment, the use of biological products, the use of active packaging, antimicrobial film-forming coatings, etc. The article describes the work of both domestic and foreign researchers.

Potapenko Institute for Viticulture and Winemaking. The subject of the study was the dynamics of the prevalence and harmfulness of grape thrips on the technical grape varieties Tsvetochnyi and Cabernet severnyi, in an uncovered culture. In the context of the widespread distribution of sugescent pests of grapes, the issue of protecting production plantings and improved basic plantings of the mother plant from them is acute, using the method of monitoring studies to signal the population size using flower traps. Therefore, the study of the development features of grape thrips, both in the conditions of the mother plant of basic plants and fruit-bearing vineyards and their influence on the economically valuable traits of grapes, is relevant. Grape thrips is a relatively new species for grape plants in the Rostov region, migrating from abandoned areas with weeds adjacent to the vineyards in search of food. To contain the prevalence of the grape thrips population below the economically significant threshold of harmfulness in agrocenoses, it is necessary to conduct timely phytosanitary monitoring. Under the conditions of two agrocenoses in 2021 and 2022, two generations of grape thrips developed during the growing season: the first at the end of May, the second at the end of June. The intensity of damage to plants of two grape varieties by grape thrips was not significant and did not exceed the economically significant threshold of harmfulness, so it was decided not to carry out chemical treatments. The presence of a stable number of pest individuals suggests that the population may be capable of wider distribution.

In present study, the results of the physiological characteristics of four pear varieties during the summerautumn season 2022-2023 are presented. Pear trees were planted in the territory of the Prikubanskaya fruit growing in the Krasnodar Region. Three varieties Leven, Lyuberskaya, Flamenco of Russian breeding and the American variety Devo were used. The pear leaves were selected three times during the summer months and in September. The content of soluble sugars and total phenols, as well as the activity of antioxidant enzymes – superoxide dismutase and peroxidase – were determined in the plant material. It was established that an increase of the level of the primary and secondary metabolites accumulation and an increase of enzymatic activity by ~20-75 % occurred in the hotter and drier 2023. The content of soluble sugars significantly increased to ~12.0 mg/g fresh weight in the leaves of the varieties Devo and Leven. The accumulation of phenolic compounds increased in all pear varieties by more than 30 % with values exceeding 27,0 mg/g fresh weight. The level of superoxide dismutase activity in 2023 averaged 13.4 unit/mg protein, which is slightly higher than the values of 2022. Peroxidase activity increased 2-4 times with maximum values of more than 8,0 unit/mg protein per min. in the varieties Leven and Lyuberskaya.

The collection includes 47 varieties. The purpose of this research is to evaluate the potential of vegetative propagation of promising varieties using the herbaceous cuttings method. The study included 18 varieties and hybrids. In the experiment 2 cutting periods were studied: 1st period – spring (II-III decade of May), 2nd period – summer (III decade of June – 1st decade of July (control). It was established that herbaceous cuttings can be carried out in 2 periods – in the II decade of May, with the placement of mother bushes in protected ground, and in the III decade of June, with the preparation of cuttings from mother plants growing in open ground. For most varieties, spring cuttings are preferable. In this case, young plants overwinter better, and the yield of marketable seedlings after 1 year of growing in pots is higher. During wintering of plants of summer cuttings, a high percentage of death was observed, which is associated with the low winter hardiness of young plants. A significant decrease in the yield of marketable seedlings after 1 year of growing in plants of summer cuttings was detected in the following varieties: Berry Awersome, Midnithe Marvell, Plam Flambe, Perfect Storm – a decrease in the yield of seedlings of I grade was observed by almost 2 times in comparison with plants rooted in spring.

The purpose of the research was to mobilize, preserve, study the gene pool, identify genes for valuable traits using DNA markers, and create varieties with high productive potential. In conjunction with this, the NCFSCHVW preserves a gene pool of 7,240 genotypes, 632 donors and sources of valuable traits. For the first time, promising DNA-markers Ps12a02a and CPPCT006, priority ones for genetic analysis, have been identified for the evaluation of sweet cherry varieties. The polymorphism of DNA-markers used for genotyping of grape varieties was established: UDV305 and UDV737, linked to the Rpv3 gene for resistance to downy mildew, GF15-42, SCGF15-02, linked to the Ren3 gene, and CenGen6, linked to the Ren9 gene for resistance to grape powdery mildew. DNA-marking made it possible to identify donor grape varieties Moldova bessemyannaya (resistance to downy mildew by the Rpv3 gene), Kishmish Zaporozhskiy (resistance to powdery mildew by the Ren3 and Ren9 genes); donor of apple tree immunity to scab according to the Rvi6 gene – elite 12/2-21-27.
