In this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same
The article presents the material of forecasting for grape
yield of next year and establishing the optimal loading if
cutting of bushes. The material includes 14 varieties of
grapes, 11 of them are technical and 3 are table ones. For
each year of stable high yield of grapes, it is necessary to
pre-set the optimum length of fruit cutting of shoots and
optimum load on the bush healthy eyes. To do this for
each variety on the eve of trimming bushes we perform
optimum productivity analysis of wintering buds of fruit
along the length of shoots, i.e. we implement forecasting
of grape yield for next year. We have a plan of forecasting
for yields of vineyards by microscopy of wintering
buds on one-year shoots of fruit ripened grapes in order
to establish the potential of embryonic establishment of
inflorescences in the central holes of buds. Based on the
analysis of buds, the indices were calculated for wintering
fruiting buds and their degree of damage during the
growing season. It was revealed, that the majority of
grape varieties under study shows high tab embryonic
inflorescences in central buds in overwintering buds for
next year yield. Higher rates at a rate of fruiting buds
were wintering in the varieties: Moldova (section 27). -
1.66; Bianca (section 6). - 1.83; Kunlean (section 15). -
1.71; Merlot (section 14). - 1.64; Saperavi (section 56). -
1.76. The lowest rates of fructification - the varieties
Muscat Hamburg (section 21) and Augustine (section
11) and were respectively 1.20 and 1.24. As a planned
productivity, we offered the optimal loading model of
cutting bushes buds. As a result of productivity analyzes
of buds along the length of the fruit shoots in 2016 we
recommended to carry out pruning of fruit annual shoots
3-4 buds of the form of AZOS-1 and the form of cordon
- 5-6 buds
