Abstract The study is aimed at assessing the suitability of plum varieties cultivated in Tambov region for the production of dried fruits (prunes). Large-fruited (average weight of more than 31 g) varieties were identified. Renklod by Kharitonovoy, Etude, Vengerka by Kursakov and Nochka are characterized by intense violet and dark purple integumentary colors. A combination of high skin strength, pulp hardness and good stone separation was found in Renklod by Kharitonov, Renklod Tambov, Etude, Vengerka by Kursakov and 23-135 Elite. A high accumulation of soluble solids, sugars, a low content of organic acids, as well as a high sugar-acid index were found in Renklod by Kharitonov, Renklod Tambov and Elite 23-135. Prunes produced from Renklod by Kharitonov, Renklod Tambov and 23-135 Elite were characterized by high commercial and consumer qualities, which makes it possible to recommend these varieties for the production of dried fruits.

The work summarized the literature data on the content of chemicals in blackberries grown in various regions of Russia and foreign countries. Much attention is paid to the level of accumulation of biochemical components: soluble solids, sugars, organic acids, vitamins C (ascorbic acid) and P (phenolic compounds). In the studied regions, a high accumulation of anthocyanins (307-651 mg / 100 g) and ascorbic acid (23.4-54.0 mg / 100 g) in blackberries was noted in the Republic of Adygea. The highest sugar content (9.9%) was in blackberries grown in the middle zone of Russia. The average content of the studied components depends not only on the region of cultivation, but, first of all, on the varietal composition of the crop. The study of 25 blackberry varieties bred in the USA, England and Australia in the Krasnodar Territory allowed us to identify the most adapted of them for cultivation in the south of Russia,the most promising varieties are Thornfree, Smoothstem and Black Satin. In the Republic of Belarus, blackberries are grown on personal subsidiary plots, the most common is the American Agavam variety, which is noted for its high sugar content and the content of P-active substances. At the Maikop Experimental Station. N.I. Vavilov, as a result of studying the biochemical composition of blackberry berries, the following varieties were identified: by the content of dry matter – Oregon, Black Satin, Thornfree; sugar content – Oregon, Silvon, Black Satin, Thornfree, Young; by the content of organic acids – Derrow, Raven (1.67%), Cherokki (1.87%); by the content of ascorbic acid – Himalaya (54.6 mg / 100 g), Derrow (45.8 mg / 100 g), Raven (45.4 mg / 100 g) and Cherokki (47.8 mg / 100 g).

The taste characteristics of berries of 26 cultivars, elite and selected forms of blackberries grown in Central Russia are presented: dry matter, monosaccharides, sucrose acid the total amount of sugars. The sugar-acid index has been calculated. The best genotypes have been identified according to the content of dry matter and sugars - Brzezina and Agawam cultivars, elite seedlings LN-4, LN-13, LN-14 and selected seedlings LN-5, LN-7, LN-8, according to the content of organic (titrated) acids and sugar-acid index - Brzezina, Black Satin, Loch Tau, seedlings of Black Satin, Cheyenne, Loch Ness - LN-6, LN-10, EV LN-13 and control cultivar Agawam. A high traits’ conjugation was established: the sugar-acid index and the content of monosaccharides, the total amount of sugars, soluble solids, as well as a high inverse dependency between the content of organic acids and the sugar-acid index. Low unreliable correlation coefficients (r = - 0.28 … + 0.13) were obtained, indicating the absence of links between the fruit weight and the content of biochemical components responsible for the taste characteristics of genotypes, which is a positive fact when creating new cultivars with high taste and a significant weight of fruits, indicating their independent inheritance.

The research was carried out with the aim of comparative assessment of varieties and selected forms of sour cherries by the chemical composition of fruits to identify the best genotypes with their subsequent use in breeding, as well as industrial, farm and collective gardening. The experiments were carried out in 2016–2019 in triplicate. The garden was laid out in 2004-2005 and is located in the southwestern part of the Republic of Tatarstan. The material for the study was 20 varieties and selected hybrids of sour cherries of different ripening periods of the breeding of Tatar Research Institute of Agriculture. On average, over the years of research in fruits of different varieties, the content of soluble solids varied within 16.69 ... 26.49%, sugars - 3.72 ... 6.35%, organic acids - 0.96 ... 2.64%, vitamin C - 11.70 ... 15.90 mg per 100 g. The variability of the content of soluble solids and vitamin C was average (V = 15.1 ... 19.3 and 10.3 ... 14.3%, respectively). The amount of sugars, organic acids and the sugar acid index changed more significantly - V = 20.9… 25.2, 22.0… 25.8 and 29.0… 37.7%, respectively. The genotype had a greater influence on the variability of the content of soluble dry substances, sugars and organic acids in sour cherry fruits (30.2 ... 65.9%) than the conditions of the year (3.0 ... 24.7%) and the interaction of these factors (11.4 ... 29.2%). A positive relationship was noted between the content of soluble solids in fruits and the sugar-acid index (r = 0.85), the content of sugars (r = 0.76), acids (r = 0.50), the sum of positive summer temperatures (r = 0.69 ); an insignificant negative relationship with vitamin C (r = -0.45) and summer precipitation (r = -0.60). Sources of a high content of soluble solids in fruits (21.84 ... 26.49%) in the breeding can be Shelangovskaya, Pamyat Sakharova, Sevastyanovskaya varieties, selected forms - Chereshnevaya No. 1, 1-11-31, 80-8, 1-10 -30 and 37-8; high content of vitamin C (15.16 ... 15.90%) - varieties Shelangovskaya, Low-growing and selective form Chereshnevaya No. 1. In industrial, farm, collective gardening it is recommended to use varieties Shelangovskaya, Pamyat Sakharova, Sevastyanovskaya.

Research is needed to better understand the influence of cell volume and fertility on watermelon transplant size and field performance in order to determine the most economic production practices. `Jubilee' watermelon transplants were grown using a 4 x 4 factorial experimental design consisting of 4 cell volumes (30.7, 65.5, 147.5, and 349.6 cm3) and 4 fertility rates (0, 1/4, 1/2, and full-strength Hoagland's solution). Transplant shoot dry weight significantly increased as cell volume and fertility increased. Increasing cell volume linearly increased watermelon number/ha and tons/ha for early and total harvest in 1995. The average weight per watermelon significantly increased for early-harvested fruit but not for total harvest as cell volume increased in 1995. Soluble solids concentration linearly increased with increasing cell volume for early and total harvests in 1995. Cell volume had no significant influence on the harvest parameters measured in 1997. In 1995, increasing fertility linearly increased watermelon number/ha and tons/ha for early harvests. Increasing fertility increased the soluble solids concentration linearly for early-harvested watermelons in 1997 but not in 1995. Fertility rate had no significant influence on any of the other harvest parameters measured in 1995 and 1997. The growing conditions and disease pressure in 1997 reduced melons/ha, yield, and soluble solids content when compared to 1995 values. The half-strength Hoagland's solution produced the greatest number of watermelons/ha, tons/ha, and the highest soluble solids concentration in 1995 and 1997. Pretransplant nutritional conditioning had no significant effect on total `Jubilee' watermelon production in Louisiana for 1995 and 1997.

BACKGROUND: Kiwifruit plants are extremely sensitive to hail storms. Black anti-hail nets are the most frequently used in kiwifruit culture, to protect both the plant and current as well as future production. OBJECTIVE: The present trial aimed to assess if the black hail net could also serve as an amelioration agent against high temperature and irradiance during the summer months. METHODS: The photosynthetic capacity, the yield, and fruit quality (carbohydrates, organic acids, phenolic compounds, and antioxidant capacity) of “Hayward” kiwifruit cultivar, both at harvest and after three months of storage were evaluated. RESULTS: Photosynthetic capacity under the net was slightly higher compared to control, while leaf temperature was always lower during the summer and autumn. The yield was significantly enhanced under the net, while the fruits exhibited higher titratable acidity, organic acids, and ascorbic acid concentration. After the storage, fruits produced from vines grown under net still had higher organic acid content, as well as total soluble solids but lower antioxidant capacity compared to control. CONCLUSIONS: Net installation above kiwifruit canopy seems to alleviate the effects of high temperature and heat load on kiwifruit vines, under saturating light intensity, inducing higher yields with good fruit quality.

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.
