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.

The information about adaptive potential of different grapes varieties in the conditions of critical negative air temperatures in winter period and influence of anthropogenic factors on grapes resistance to stresses is presented. Agricultural and technical methods purposeful of resistance increasing and recovery of grapes plants injured from frosts are given

The research is carried out in the Riesling vineyard under the agric-ecological conditions of the Black Sea area of viticulture (Anapa). In is known that the technical Riesling grapes has a high productivity of shoots. Also we know, that there is a close relationship of formation and differentiation of embryonic inflorescences of grapes varieties from the genetic characteristics, hormonal plants status, balance of nutrition and weather-conditions. The task of the research was to identify the effect of air temperature and density of bushes planting on laying of generative organs in the buds of Riesling grapes. It is shown that under the agric-ecological conditions of the Black Sea area of the Southern Russia viticulture the formation of rudimentary inflorescence occurs sequentially. Monitoring of grapes plants development shows that the first inflorescence was formed completely to July 1, the second inflorescence - to 22 of July. The period from the appearance of generative hillock to the formation of the first inflorescence was 25 days. On the differentiated inflorescences the coefficient of fruiting in the middle of July (K1) was the largest (> 1.0) in the area of 4-6 buds. In subsequent periods (22.07 and 05.08) a zone of differentiated inflorescences with a coefficient of fruitage > 1 has expanded from 2 to 7 buds. It was found that more intensively the differentiation of embryonic inflorescences takes a place in the rare planting of vineyards (3,5 × 2,0 m), compared with a tight planting (2,5 × 1 m). The more intensive differentiation of embryonic inflorescences of Riesling grapes is noted in a zone 2-7 buds. This fact must be taken into account when the calculating of the vines load and the execute of pruning are needed.

Biological features of grapes plants, their selective insistence to temperature condition, and especially to minimal air temperatures, limit an area of its growth. Cultivation of plantings under severe climatic conditions is followed by deterioration of grapes quality, damage of separate bodies of plants up to full death of bushes. Under these conditions the problem of formation of steady ampelocenoses and prevention of sparse grapes planting is actual. For providing an objective assessment of vineyards condition the object is to develop a technique of definition of sparse grapes plantings, and carrying out of monitoring with high precision. As object of research were used the most wide spread grapes plantings in the North Caucasus Region, including the largest producers as Krasnodar Region, Republic of Dagestan, Stavropol Region and others. Scientifically reasonable method of definition of sparse grapes plantings is presented in the article. When developing a method for reliable inspection of orchardsfor sparseplanting the selective accountsin the each row and with an interval through 1, 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20 rows are carried out.Presentability of selectionfor carryingout of accountsis determined by a difference of sparse indicators in the plantings receivedin the selective rowsand in an each row. It is establishedthat in the process of reductionof quantity of selective rowsfor calculation the mistake graduallyincreases.The results of the carriedoutresearch have shown-thatfor scientifically based inspection of vineyards for sparseplantings with highprecision,at a sign toleranceto 5%, the accounts needto be carriedout with an intervalthrough five grapes rows,and sixth rowshould beconsideredas a rowthatneed calculation.
