The productions technology of fruit saplings for different types of gardens demands of selection of rootstocks of certain growth force and the differentiated approach to technology of saplings cultivation. Quality of the shoots, landed in the first field of nursery, is a leading factor of ensuring of standard saplings receiving. The purpose of this research is to pick up the root stocks of low growing group connected with the requirements of carrying out of grafting at the height of 40 cm, possessing by rather intensive vertical growth of shoots, high yield of standard layers and their minimum branching. For realization of tasks the modern methods of field and laboratory research are used. These indicators were analyzed: receiving of standard layers from unit of area, parameters of overground part of layers, the intensity of rooting, the property to branching of annual layers, the curvature of layers. It is established that quality of layers substantially was defined by rootstocks type. The research showed that the control CK2 rootstock yields to MM102 and CK4 rootstocks. So, MM102 rootstock on the average in two years had the production of standard layers on 27,4 thousand/hectare higher, than CK2 and had not the curvature of shoots that is an important factor for using of a high grafting. The CK4 rootstock had not thorn prickles of shoots that increase its technological efficiency in the nursery fields. M9 and M9EMLA rootstocks yield to a control rootstock on production of standard layers, they have a big branching of annual shoots. For conducting of high grafting MM102, CK4 and M9EMLA rootstocks are recommended.

In the struggle for a saler's market of fruitage production the producer with high fruits quality and their low prime cost is winning. For economy of production costs of fruit's the low-cost elements of technology are introduced. The Stavropol Experimental Station of gardening tested the technology of a garden using the saplings on the rootstocks with grafting at the height of 40 cm. Increase in deep of saplings during when landing on 20 cm more than previous recommendations allows you to increase trees fixation in the soil and to get rid of an expensive support. The introduction of the offered technology significantly depends on quality of saplings with grafting at the height of 40 cm, profitability of their production and selection of low growing rootstock which is optimal conforming to requirements of the technological process. For selection of low growing rootstock corresponding to the production technology of saplings with a high grafting the dwarf and semi-dwarfish apple-tree rootstocks: of M9, CK4, T337, M9EMLA, MM102 and CK2. The carried out research showed that the T337 dwarf rootstock and MM102 semi-dwarfish rootstock are the most technological for cultivation of saplings with a high grafting. They have the straight well rooting layers, in the first field of nursery the central trunk doesn't deviate from vertical position. To the time of carrying out of grafting the height of plants reaches 95-106 cm. The central trunk has a thickness of 8-10 mm at the height of 40 cm and it allows you to execute a high grafting qualitatively. The receiving of standard saplings on these rootstocks with grafting at the height of 40 cm reach 98 % of quantity of all layers landed in the first field.

The prospects of application biostimulants of growth to increase the resistance and stability of fruiting of fruit crops are discussed. Fruit crops are exposed to stress factors, both biotic and abiotic. Climate changes, especially regional weather conditions, characterized by a higher frequency of extreme manifestations of abiotic stress, strongly affect the growth and productivity, the quality of fruit plant products. Increasing the productivity of fruit crops is achieved by regulating the main factors of the production process. One of the promising areas of modern horticulture for increasing the resistance and formation of stable productivity of fruit agrocenoses is the development of a system for the application of biostimulants. Groups of biostimulants, their classification, characteristics and mechanism of action on plants are considered. The analysis of the influence of biostimulants on the stability and productivity of fruit crops is presented. It is shown that biostimulants in low concentrations have a growth-stimulating effect, enhance plant metabolism and increase the degree of absorption of nutrients from the soil. Their application makes it possible to increase the efficiency and reduce the amount of mineral fertilizers used in the management system for garden crops cultivated using intensive technologies. The role of biostimulants in the preservation of soil fertility of garden agrocenoses is revealed, since these drugs can stimulate the activity of useful soil microorganisms and optimize the absorption of nutrients from the soil by plants. The anti-stress properties of biostimulants were studied and analyzed to preserve the productivity level of fruit plants, the quality of fruits in conditions of drought, salinity, low and high temperatures. The available developments in the field of the application of biostimulants in horticulture indicate the prospects of applying the research results for further improvement of intensive technologies for cultivating fruit plantations based on methods of biologization and ecologization of production processes.
