abstract 1231609125 issue 123 pp. 1888 – 1894 30.11.2016 ru 221
From 2011 to 2015 in the laboratory conditions there were studied the physical properties of absorbents in the controlled environment. There was defined that in the variant of the "soil+water" the usual colloidal mass is formed and in variants "soil+absorbents+water" - a mixture of soil and gel. There was determined that the least diurnal evaporation was fixed at the use of the mixture: soil+ preparation “Ecogel-1”. In the control variant of the experiment the full water evaporation was marked on 31st day after beginning of the experiment, in the variant with the use of the absorbent Aqua Life the whole water evaporated on 48th day, and at the use of preparations Ecogel-1 and Ecogel-2 the duration of evaporation of the same amount of water supply at temperature 22-24оС and air moisture in 55-60% continued 57-65 days. In the result of five-year laboratory researches there was determined the possibility of development of water-saving technology for fruit plantations. When we used absorbents (granules, powders) in planting process and watering resulting the gel-like mass completely collapses the root system of fruit plants and the operation of the system "soil-roots-leaves" will not depend on the physical condition of soil and environment due to water consumption for transpiration

abstract 1221608077 issue 122 pp. 1116 – 1124 31.10.2016 ru 229
Nowadays, fruit trees are subjected to influence of abiotic stress-factors. The reaction of fruit plants on the influence of media plays an important role. Experiments were conducted in two (Northern and Central) fruit zones of the Krasnodar region since 2013 to 2015, there was shown the possibility of application of hydroabsorbents as a stable source of water supply of fruit trees in specific natural conditions of the South of Russia in the conditions of field experiment. There were shown the peculiarities of technological ways of water supply of fruit trees in specific natural conditions of the south of Russia. There was determined that the necessity in watering of a garden’s plots with the use of hydroabsorbents Ecogel-1 and Ecogel-2 with the supporting of soil’s moisture in 80% in Northern zone in the end of May, in central fruit zone in the middle of May. There was proven that the application of hydroabsorbents Ecogel-1 and Ecogel-2 guarantees the stable water supply in limits of 75-80% from NV since planting in apple-trees of varieties of Renet Simirenko and Golden Delicious grafted on the stock M9 and planted on the scheme 4,0 х 1,0 м during three years.

INFLUENCE OF ABIOTIC FACTORS ON THE FORMATION OF COMMERCIAL APPLE CROPES AND WAYS OF ITS OPTIMIZATION IN THE SOUTH OF EUROPEAN PART OF RUSSIA

abstract 1531909029 issue 153 pp. 294 – 305 29.11.2019 ru 6
The work is devoted to studying the nature of the influence of individual abiotic factors of the southern territories of Russia on the features of the formation of an economic apple yield in adjacent years and the justification of the possibility of adjusting the course of this process in adverse environmental conditions. The studies were carried out in 2018-2019, which are distinguished by the manifestation of weather anomalies in the summer-autumn period. Field experiments were performed at the farms of the Kuban horticultural zone on soils suitable for planting fruit stands: leached and typical chernozems. The features of the development of plants of apple trees of winter varieties Kuban crimson and Fuji on the stock M9 were studied. In the experiments, an option is provided using foliar treatment of plants with Pomaset fertilizer. The effectiveness of the formation of the economic apple crop depends on the biological characteristics of the used pomological variety, as well as the temperature and moisture conditions during the growing season of the plants. Soil conditions do not significantly affect the course of this process. The probability of losing the potential apple crop at the XII stage of organogenesis (pre-harvest decay) under the influence of abiotic summer stressors: high air temperatures and water deficiency is noted. With the manifestation of extremely high air temperatures in late summer and during the autumn months, a significant increase in the duration of vegetation of various (especially strong-growing) apple varieties was recorded, causing a shift in the process of differentiation of generative buds (stages III-IV of organogenesis) to a later date, and, as a result, - decrease in potential plant productivity in the next season. With the manifestation of abnormal weather conditions, the prospects of foliar treatment of trees in the second half of the growing season with Pomaset fertilizer, which optimizes the fruiting of the apple tree in adjacent years, are shown. At the same time, the fruit yield in the current year is increasing by 9-14%, and in the next season - by 7-10% in comparison with the control values

abstract 1231609124 issue 123 pp. 1878 – 1887 30.11.2016 ru 250
Introduction of new elements of fruit cultivation technology into production is one of the elements of intensification of the branch. The problem of providing plants with moisture is the key in modern technology. The purpose of the research is a development and manufacturing of innovative methods of water supply of modern fruit plantations. Researches were conducted in two fruiting zones of the Krasnodar region (Northern and Kuban) with the aim of assessment of influence of different ways of water supply on the growth and productivity of apple-tree varieties: Idared and Gala Schniga grafted on the stock М9 and planted in 2012 due to the scheme 3,5x0,8 m. There was determined that the application of the absorbent Aqua Life and absorbents with the addition of recommended elements (Ecogel-1; Ecogel-2) increase the acclimation rate of seedlings on 2- 6%. The presence of proper conducting system to supply with the moisture and nutrients the overhead part (roots-leaves) and a large number of photosynthezing apparatus promoted to obtain the high-quality fruit productivity, accumulation of phytomass and increase of fruit quality. We have found, that complexes of hydroabsorbents on the basis “Aqua Life”, “Ecogel-1” and “Ecogel-2” in conditions of Kuban in fruiting apple-tree plantations on dwarf stocks showed the high effectiveness on water supply, for the first time

MORPHO-BIOLOGICAL AND ANATOMICAL CHANGES IN THE OVERGROWING WOOD OF THE GALA APPLE TREE DEPENDING ON THE USE OF THE GROWTH REGULATOR

abstract 1541910028 issue 154 pp. 289 – 299 30.12.2019 ru 6
The work is devoted to studying the nature of the effect of various doses of the drug called "Regalis" on the formation of the vegetative and generative organs of apple plants. Years of research - 2016-2019 Field experiments were carried out in JSC company "Agrocomplex" named after N.I. Tkachev in the Vyselkovsky district. Plantations were laid in 2007. Planting pattern 4.0 × 1.0m., garden irrigated, with support. The soil of the site is ordinary carbonated black soil (chernozem), the thickness of the humus layer is up to 120-140 cm. As a result of field and laboratory studies of the condition of 9-12 year old Gala apple trees grafted on P-59 rootstock, it was established that the annual treatment of apple trees for different phenophases with a preparation Regalis at a dose of 1.25 kg / ha has a significant effect on both the size and the number of vegetative and generative formations. It was determined that triple treatment of apple trees with regalis in 43.11% reduces the number of shoots longer than 60 cm, and double - by 31.39%. Structural changes in the distribution of vegetative and fruitful formations per 1 meter were noted in axial branches of the first order. Under the influence of the drug, the number of full-fledged “closed” buds in 2017 increased by 88.8%, and in 2018 by 70.9% compared with the control. The use of triple treatment with Regalis significantly reduces growth activity and has a positive effect on the passage of organogenesis of apple flower buds

STABILITY OF SWEET CHERRY PLANTS TO LOW TEMPERATURES OF THE SPRING PERIOD: POSSIBLE INDICATORS AND MECHANISMS

abstract 1592005020 issue 159 pp. 294 – 302 29.05.2020 ru 4
These studies are devoted to determining the characteristics of changes in some physiological and biochemical parameters of sweet cherry plants that arise under the influence of the main damaging factor of the spring period - frost and associated with the resistance of the plant organism to the action of stressor. The studies were carried out in 2012 and adjacent 2018-2019 in the fruiting plantations of cherries of the Kuban zone located on horticultural soils: leached chernozem and alluvial meadow. We studied sweet cherry varieties of different resistance to frost. Samples for analysis were selected according to the background of naturally prevailing positive air temperatures. The plant material was frozen in the Binder climate chamber KB 53 for 4 hours at a temperature of 2.5 ± 0.2 ° C. According to the results of the experiment, sweet cherry plants that differ in early flowering are more susceptible to the temperature stressor in the spring in comparison with late flowering plant organisms. Meanwhile, the resistance of plants to frost depends not so much on the date of differentiation of the generative buds, but on the efficiency of the physiological and biochemical activation mechanisms under the influence of an unfavorable synthesis factor in the flowers of indolylacetic acid, which is responsible for the efficiency of the onset of fruit formation, and ultimately a more complete implementation potential productivity. An important indicator of the stability of a plant organism is the degree of change in the content of this phytohormone
