The degree of defeat of grapes plants by harmful organisms depends on biological features of the cultivated varieties and their adaptive potential and efficiency of protective measures. Under the conditions of Krasnodar Region now there are about 30 harmful organisms capable to destroy more than 10% of a harvest and even to cause the death of bushes. The wine prepared from grapes of the sick bushes is worse on qualitative indexes that the wine materials from grapes of healthy bushes. Our task is to study the influence of the scheme of planting of Riesling grapes bushes on a phytosanitary condition of plantings. Adaptive reaction of plants in case of different schemes of landing was researched. Research is carried out under the agric-ecological conditions of the Black Sea area, the central subband of wine growing of Krasnodar Region (Anapa). The observations of a phytosanitary condition of grapes plants during their vegetation we carried out using a technique of evaluation of varieties resistance to the dominating harmful organisms. In the article the results of studying of a susceptibility of plants to harmful organisms at the different density of landing of Riesling grapes bushes are presented. The steady tendency of spreading and strengthening of intensity of mildew development is established in case of increase in density of bushes planting. The greatest spread and intensity of disease development were observed in the grapes plantings in case of density of bushes planting 2,0 × 1,0 m, the smallest spread - at the landing density of bushes - 3,5 × 2,0 m. It is shown that degree of grapes defeat increases in case of decrease of row-spacings width from 3,5 to 2,0 m and in case of decrease of distance between bushes from 2,0 to 1,0 m, irrespective of row-spacings width.

The reaction norm of the introduced wine grape variety Merlot in unstable conditions of the moderately continental climate of the south of Russia has been established. The research was carried out in the agroecological conditions of the Black Sea viticulture zone of the Krasnodar region in the industrial vineyards of the GC Abrau-Durso using modern methods of field research. Agrobiological accountings were carried out using the methods of agrotechnical study of grapes. The climate at the research areais moderate continental. The average annual air temperature is 14.1 ºC, during the growing season (May September) is 22.2 ºC, the maximum rises to plus 37.0 ºC, the minimum during the wintering period of grapes falls to minus 19 ºC. The annual amount of atmospheric precipitation is 544 mm, during the growing season 208 mm, during the active growth of grape berries (II. June-III. august) 96 mm. The grape plant reacts with the modification variability of phenotypic traits to the variation of environmental conditions. The lower limit of the modification variability of the cluster mass is 98 g and the upper limit is 121 g., the grape yield is 3.3 kg/bush and 6.8 kg/bush, the sugar content of the grape berries juice is 20.1 g/100 cm3 and 21.6 g/100 cm3 . The reaction norm is 23 g, 3.5 kg/bush and 1.5 g/100 cm3 , respectively. Against the background of the application of fertilizers, the lower and upper limits of the modification variability increased respectively: the cluster mass by 16 % and 9 %, the grape yield by 48 % and 16 %, the sugar content of the grape juice of by 10 % and 7 %. The reaction norm decreased: reduction for the cluster mass as phenotypic trait was 22 %, for the grape yield 14 %, and for the sugar content of the berry juice 67 %.

Annotation

The frost resistance of the varieties of grape of different ecological and geographical groups and periods of ripening in the natural and simulated conditions is studied. During the period 2006 2011 more later entry of the plants of grapes into the state of organic dormancy is established. On the basis of es-timation of the complex of physiological and biochemical indices it is established that the frost resistance of grapes of Euro-AmurAmerican (variety Krystall) and European origin (variety Barhatniy and Cabernets Sovinyon) is caused both by the high stability of the protoplasm of cells to the dehydration and cellular membranes to the destruction; varieties of Euro-American ori-gin Dostoyniy, Pervenets Magaracha, Caber-net AZOS - the stability of theprotoplasm of cells to the dehydration also of varieties Krasnostop AZOS and Ach Chakrak by the stability of cellular membranes to the destruction

Annotation

Experimental studies are suggested that ta-ble varieties of grapes are most responsive to their holding on the large form of bushes. Productivity of bushes formed by the type Ombrella and DZHZ increased by 1,5-3 times by improving the use of photosynthetically active radiation

Annotation

The loading of grape bushes with a harvest must be carried out so that the most productive zone of grapes shoot could provide the largest level of realization of economic efficiency potential of varieties and high quality of grapes and wine production. The purpose of this work is to study the growth processes of grapes plants, and to determine the conformity of natural lows of placement of the most productive zone along shoot length and to optimize the regulation regime of growth functions and qualitative indicators of a harvest. The experimental research have been carried out under the very drought conditions of 2015 vegetation in the Black Sea agric and ecological viticulture area in the field stationary experiment. An object of our research is a Riesling Rhine technical grapes with the different scheme of bushes planting. In the course of work carrying out the unequal laying of grapes clusters along a shoot length of plant was found. The results of carried out research have shown that in years with the big deficit of an atmospheric precipitation and the bigger solar activity during vegetation the most productive area of shoot length of a grapes plant there was the fourth knot. In this zone of shoot the mass of grapes clusters was the greatest, but the smallest mass of clusters was on the second, first and fifth knots of shoot. On the other knots of shoots the grapes clusters were not observed. On the basis of the results of the field experiment we made the conclusion that for loading regulation of grapes bushes with a harvest it is recommended to leave on plants the most developed and large grapes clusters on the fourth shoot's knot and if it is necessary to remove the small and underdeveloped grapes clusters on the first and second knots of shoots.
