OPTIMIZATION OF THE LENGTH OF TRIMMING AND THE LOAD OF BUSHES WITH BUDS OF DIFFERENT VARIETIES OF GRAPES IN TAMAN

abstract 1241610074 issue 124 pp. 1162 – 1181 30.12.2016 ru 274
Numerous studies have found a different quality of the buds along the length of the fruit arms, which expressed various degrees establishing embryonic inflorescences in the central buds. It is revealed that many of the grapes have more fruit-bearing eyes formed on average (4-6 knots) and upper (7 to 10 knots) levels of fruit escape, compared to the lower (1-3 nodes) layer. In connection with the different quality of the buds along the length of fruit vines should be used and different ways of cutting them. It is necessary to consider the biological characteristics of varieties, ways of doing and shaping the bushes, the weather conditions of the area during the growing season and relative calm. To receive annually a stable high yield of grapes, we must first set the optimal length of pruning fruit shoots and optimal load on the Bush healthy eyes. This requires for each class on the eve of trimming bushes to carry out the analysis of the wintering holes along the length of the fruit shoots and to identify the embryonic fruitfulness of Central buds, i.e. to carry out the prediction of grape yield next year. The article presents data on the formation of the embryonic fruitfulness of Central buds of wintering buds at the Taman group of grapes – Arcadia, Viorica, Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot white, Riesling, Saperavi, Traminer pink, Tsimlyansky black, Chardonnay. Found higher rates of embryonic fruitfulness of Central buds buds in the studied grape varieties - Chardonnay, Riesling, Viorica, Hibernal, Merlot, Moldova, where the coefficients of fruiting ranged from 1.40 m from Riesling to 1.69 from Merlot; factor productivity of 1.58 from the Chardonnay to 1.77 from Merlo. The high percentage of fruitful buds from 80,8 from Cabernet Sauvignon to 95.6 in the cultivars Merlot and Chardonnay. A higher percentage of eyes with 2 embryonic buds in the cultivars Merlot and Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of grapes next year to trim the bushes on the proposed method will provide a full crop of grapes
