The method of formation and mainte-nance of bushes in the nursery plays a primary role in the measures to increase the efficiency of rootstock cultivation. The formation of bushes is an important agrotechnical mode, regulated the growth and development of plants and the quality of planting material. The best way of bushes formation, is the way when the greatest yield of qualitative cuttings is ensured from an unit of area at the lowest cost. The following main principles determine the theoretical basis for choosing the forms of grape bushes in the nursery of vine rootstocks: they are the construction of bushes and the biology of the varieties used should be maximally adapted to local conditions of growth, to desrease in the negative influence of abiotic stressors, to respond to varietal characteristics, and to be convenient for manual and mechanized work. The purpose of this work is the theoretical substantiation of the development of effective methods of plantations growing grape nursery that provide an increase in the yield and quality of standard cuttings under conditions of the grafted crop cultivation. This study consisted of a review of Russian and foreign literature, articles, reports and electronic sources (magazines, books and websites) on this subject, related to the formation of wine rootstock nurse-ry plantation. Despite the existence of a wide variety of forms and ways of vine bushes keeping, there are a number of deficiencies that adversely affect the quality and yield of cuttings from an unit area, and making it more difficult to control the diseases and vermins. Therefore, at present, the creation and development of new resource-saving ways of vine rootstock nursery maintaining for the production of high-quality cuttings is one of the urgent tasks in the field of grape nursery keeping.

In the conservation and improvement of soil fertility, ensuring the productivity and stability of agrolandscapes, the ecosystems of perennial grasses are of particular importance. Impact on the soil of sideration, increase in organic mass in the soil and application of fertilizers improve it, form plantations resistant to diseases and vermins. Perennial grasses of agrolandscapes are traditionally used as one of the most effective factors of soil formation, improvement and protection of soils. Such system significantly reduces the cost of soil maintaining and the cost of finished products. An integrated approach to the maintenance of a grape bush from laying to harvesting can ensure not only the obtaining of high-quality products, but also the preservation of the productivity of perennial agrocenoses throughout their cultivation period. The object of our research is the grapes of the Cabernet Sauvignon and the Chardonnay of 2012 planting. The methods of research are laboratory-analytical and field stationary. Agrobiological registrations were carried out in 6 model bushes of grapes in each variant of the experiment. As a result of the research we carried out, it has been established that soil sowing through one vineyard spacing of Lolium perenne L. (40 %) and Trifolium repens (60 %) positively influence increasing in the yield capacity and improving the quality of the grape juice of the varieties studied. The best organoleptic characteristics of the wine samples of from the Cabernet Sauvignon grapes were obtained in the variant with soil turf soving through one row spac-ing, from the Chardonnay grapes the best wine samples were obtained in the variant with black soil.

The results of physiological and biochemical studies frost-resistant of grape varieties are presented in the article in natu-ral and simulated environments. Ranges of variation of the Optima biochemical parameter of frost resistance (in the state of deep and compelled rest), allowed grape varieties such as Crystal, Krasnostop, AZOS, Dostoyniy to survive in extreme winter conditions of Anapa-Taman region, are established in result of study of stress factors influence of winter period on bio-chemical composition of plant organs of highly resistant to low temperatures grape varieties.

The most accurate criterion for determining the length of pruning of grapes shoots is the productive zone of embryonic inflorescences. To more fully realization of potential of the economic grapes productivity, the pruning is carried out with the left of maximum number of embryonic inflorescences and the unproductive part of the shoots removed. In different grape varieties the productive zone is not the same and it varies along the length of the shoot. In addition to the biological dependence of the productive zone of plants shoots, the anthropogenic factors have a significant effect on the formation of embryonic inflorescences. Pruning while preserving the productive zone of grapes shoots contributes to the sustainable development of the viticulture industry. The purpose of the work is to establish the regularity of embryonic inflorescence formation and to optimize the length of pruning of Levokumskiy grapes shoots. Embryonic fruitage was determined during the period of deep (physiological) dormancy of plants by microscopic examination of the central wintering buds on typical grapes shoots. In the process of research it is found that the dependence between the fruitage and fertility rates of embryonic shoots in the central wintering buds of the Levokumskiy grapes varies on the average daily air temperature in September and November. The correlation coefficients range is from 0.36 to 0.77. You have shown the regularity of a differentiated inflorescence formation along the length of embryonic shoots. The coefficients of fruitage (K1) and the fertility (K2) of embryonic shoots of Levokumskiy grapes grow as the buds are removed from the beginning of the shoots. The maximum values of the coefficients are fixed in the zone of 5-6 buds. In this regard, to obtain the greatest harvest of the Levokumskiy grapes, it is recommended to prune the fruit shoots into 6 eyes.

The purpose of this work is to study the influence of natural and anthropogenic factors the growth, development and formation of the photosynthetically active surface of grapes plants. The research was carried out in 2015 in a stationary field experiment in the EPF of the Anapa Zonal Experimental Station of Viticulture and Wine-Making, in the Riesling Rheinsky vineyard under the conditions of an abnormal man-ifestation of weather factors with an acute deficit of atmospheric precipitation. A differentiated effect of the planting scheme of bushes on the growth of grapes shoots and leaves was established in the process of research. The rate of vine development is closely depended on the genetically de-termined reaction of the variety to the anthropogenic and natural factors of cultivation. It is shown that the most influenced slowing down of the growth processes of the grapes plants are the densified ways for bushes placing with a row spacing of 2.5 m. The most active growth processes are observed in the orchards with a row spacing of 3.0 m. Under stressed plant growth conditions, the most active growth of shoots is noted at an average density of planting bushes of grapes � 3.0 × 1.5 m. With compacted arrangement of bushes, 4000 pcs / ha according to the scheme 2.5 × 1.0 m, the growth activity of shoots is much lower. Crown of grapes bushes in such orchards are poorly lit, leaves receive less solar energy. It is noted that the growth rate of the leaf blade is similar to that of shoot growth. The largest leaves were at a density of bushes of 3.0 × 1.5 m. We made a conclusion that a differentiated approach when using different schemes of planting bushes in the grapes plantations allows to controll the growth processes of grapes plants.
