AGROBIOLOGICAL EVALUATION OF NEW STRAWBERRY VARIETIES IN THE CONDITIONS OF THE PRIKUBANSKAYA ZONE OF GARDENING IN THE KRASNODAR REGION

abstract 1491905016 issue 149 pp. 81 – 91 31.05.2019 ru 109
The article presents the results of studies on the biological characteristics of growth and fruiting, as well as the yield of adaptive varieties of strawberries in the conditions of the Prikubanskaya horticulture zone of the Krasnodar region. The objects of study are new and promising varieties of strawberries: Zenga-zengana (k), Onda, San-Diaz. The experiments were performed using the method of randomized reps. In the experiment there are 3 options, in each there are three replications of 20 plants. Variants and repetitions are placed sequentially. Agricultural records of the growth and fruiting of strawberry plants were carried out according to generally accepted methods; statistical processing of research results was carried out using the analysis of a variance method described by B.A.Dospehov. The results of our research showed that Zenga-zengana bushes (control) turned out to be the tallest. In the Onda variety, the height of the bush is 2 cm less than in the control variety; and San Diez varieties are 4 cm, respectively. It should be noted that the most undersized plants require a smaller area of nutrition. It has been established that flowers pollinated a few days after their disclosure develop more rapidly into berries than those that were pollinated immediately after opening. Pollen in flowers of the first order is less than in flowers of the third or fourth order. The stamens of the first flowers are often underdeveloped, their pollen is released and germinates worse. In our experience, the average weight of fruits and the yield as a whole depends on the biological productivity of the varieties. Onda was the most fruitful variety, and the rest varieties were at the control level

abstract 0460902001 issue 46 pp. 1 – 7 27.02.2009 ru 3297
The article shows the results of the impact of foliar nutrition on crop and product quality of the Grenny Smith apples. Also the impact of the agricultural practices to fruits saving ability is discussed, as well as their quality in terms of sugars, acids and vitamin C. It was found that the use of 3-fold foliar nutrition feeding with nitroammofoska impacts positively on the results of storage.

PECULIARITIES OF VEGETATIVE REPRODUCTION OF PERSPECTIVE VARIETIES OF RASPBERRY BY THE METHOD OF MARKING IN THE CONDITIONS OF THE KRASNODAR REGION

abstract 1371803015 issue 137 pp. 61 – 76 30.03.2018 ru 129
In conditions of field and laboratory experiments, there were learned particular properties of vegetative reproduction of raspberry varieties. During the experiment, there were used Scromnitza, Glen Ample, Miraj varieties. In field conditions, there were made phenological accounts, also there were made biochemical observations of quality markers of fruits of observed raspberry varieties, based on department of laboratory of pomology of Kuban SAU. Optimal correlation of common sugars and acids, which define fruit tastes, seen on raspberry variety Glen Ample. Maximal amount of planting stocks obtained at reproduction of root stems with a more than 5 mm diameter. Glen Ample had the biggest (in comparison with other varieties) result of output amount of daughter plants. According to commercial – attractable level, raspberry varieties arranged in increasing order: Scromnitza, Miraj, Glen Ample. During the assessment of winter hardiness (based on degree of harming generative buds by frosts), Miraj was positively underlined

PRODUCTIVITY OF APPLE TREES DEPENDING ON CROWN FORMING IN THE CONDITIONS OF THE PIEDMONT ZONE OF GARDENING IN THE KRASNODAR REGION

abstract 1562002002 issue 156 pp. 17 – 25 28.02.2020 ru 31
The article presents the results of studies on the influence of the conditions of the Piedmont horticulture zone of the Krasnodar region and the shape of the crown on the productivity of apple trees. Objects of study were trees of winter apple varieties Idared and Renet Simirenko grafted on MM 106 rootstock. The trees were planted according to the 5 × 3 m pattern. In the eighth year, the rounded crowns were transformed into flattened across the row (from the eastern and western sides of the tree) to crown width 2.0 ... 2.5 m. Orientation of rows was from east to west. The garden is located on the northern slope with a slope of 3 degrees. Scheme of experiment: option 1 - sparse-tier crown (control); option 2 - flattened crown. In the experiment, 2 variants; in each variant, 10 typical trees were taken. Repetition tree plot. The place of the experiment is Abinsky district of the Krasnodar region. Agrocounts of indicators of fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was carried out by the method of analysis of variance described by B.A. Dospekhov. The results of our studies showed that flattening the crown of apple trees contributes to an increase in the number of fruits formed on them per unit volume of the crown in the variety Idared to 10.1 kg or 1.87 times, and per m2 of the projection of the crown to 15.5 kg or 1.72 times more than crowns without flattening. In the variety Renet Simirenko, the number of fruits according to the same indicators increases by 1.86 and 1.74 times. Also, when flattening crowns, the yield of apples from one tree in the Idared variety increases by 9.6%, and in the Renet Simirenko variety decreases by 7.7% compared with the control

THE EFFECT OF FOLIAR TREATMENTS WITH MINERAL FERTILIZERS ON THE YIELD AND BIOMETRIC INDICATORS OF CUTTINGS

abstract 1471903012 issue 147 pp. 31 – 42 29.03.2019 ru 69
In this article, the influence of foliar treatments with complex fertilizers (Polimiks-agro, Sprühdünger 2) and a growth regulator (SeaweedMix) in the cultivation of rootstocks and seedlings given the concentration of drugs and phase of plant development. The positive effect of fertilizer "Polimix-agro" on physiological processes in plants of SC2U apple rootstock in the formation of adaptive resistance to abiotic stresses of the summer period, where the best water-holding capacity of the leaves than in the control. It was found that a single non-root feeding in the uterine growth regulator called SeaweedMix when reaching rootstocks height of 10-15 cm, allows to increase the yield by increasing the growth activity, increase the standard of layering with a decrease in the number of lateral branches, as well as 3-fold non-root fertilizing fertilizer Sprühdunger 2 provided an increase in the quality of rootstocks on the diameter of the trunk and height

THE INFLUENCE OF APPLE-TREE CROWN FORMING ON THE FRUIT QUALITY IN THE CONDITIONS OF THE FOOTHILL ZONE OF THE KRASNODAR REGION GARDENING

abstract 1511907023 issue 151 pp. 255 – 264 30.09.2019 ru 27
The article presents the results of studies on the influence of the conditions of the foothill horticultural zone of the Krasnodar region and the crown shape on the agrobiological characteristics of the growth and fruiting of apple trees of the Idared and Renet Simirenko varieties. The objects of the study are Idared and Rennet Simirenko, trees of winter apple varieties, grafted on MM 106 rootstock. Trees were planted according to the 5 × 3 m scheme; crown width 2.0 ... 2.5 m. Orientation of rows from east to west. The garden is located on the northern slope with a slope of 3 degrees. The scheme of experience: option 1 - sparse-tiered crown (control); option 2 - flattened crown. In the experiment there were 2 options, in each option 10 typical trees were taken. Repetition: tree - plot. The location of the experiment is the Abinsky district of the Krasnodar region. Agricultural records of growth and fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was performed by the method of variance analysis described by B. Dospekhov. The results of our studies showed that when flattening crowns, the variety Idared increases the average weight of apples by 22.9%, the yield of fruits of the highest and first grade by 43.6%, the intensity of integumentary coloring of fruits in the peripheral zones increases by 1.44, and in the center crowns 2.7 times, compared with sparse-tier crowns. In the variety Renet Simirenko, the fruit weight increases by 8.9%, the yield of the highest and first grade fruits by 14.6%, the number of fruits with color by 18.7%. Thus, in apple orchards with a 7 x 4 m planting pattern (on MM106 stock) under the conditions of the foothill horticultural zone of the Krasnodar region, flattened tree crowns should be formed for the Aydared variety (aged 14-15 years), which significantly improves the quality of the products
