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
The article presents data on the formation of the embryonic fruitfulness of central buds of wintering buds grapes of different origins in the period of relative calm of grapes and early spring period in dynamics with presence of positive air and soil temperatures
Extraction of the DNA from leaves of genus Vitis is a very difficult task, as a grape has a lot of elements, which make difficult to use it in the genetic manipulation. In that article used the methods of extraction of the DNA with silica (SiO2) particles as the absorbent material for getting better quality DNA
In the present article, the new method of DNA extraction from fresh and herbarium leafs of grape to their subsequent sequencing was described
This review article highlights a new method of DNA extraction from herbarium leaves of grapes for use in PCR-analysis
Characteristic of chemical composition of varieties of grape cultivated in the Central zone of Krasnodar region and quality of juice produced from them is given in the article. Varieties for manufacturing of high-quality juices are recommended
This article presents the possibilities of using organic fertilizers, which allow you to recharge grape raw material with biologically active substances and improve the nutritional value of wine production. The influence of organic fertilizers on activation of process for detoxification of soil toxic compounds has been measured, ensuring food safety of raw materials for the production of grape wine products by reducing of hazardous chemicals. The use of biotechnology preserves and also enhances the uniqueness and diversity of the chemical composition of the grape raw material. We have established that after the four-year application of biotechnology the content of toxic compounds in grape raw material was reduced by 7%, and the concentration of biologically active substances increased in 1,5-2% times in comparison with the production of commercial plantations
The newest wine grape variety Eftihiya with aromatic pink colored skin (in Greek the name means “happi-ness”) was breed with hybridization at the Athens In-stitute of Viticulture by P. Zamanidi, L. Troshin and P. Radchevskiy in 2005 by crossing the Greek varieties and Malaguzya with Eurasian Traminer pink. Dura-tion of production period from bud burst to harvest 146-155 days. Yields are very high: 25-30 t / ha. Modal mass of clusters is 250 g. Bunch is conical, me-dium density. Berry is medium, short elliptical, pink colored, with a thick wax coating. Pulp and juice with the expressed varietal flavor, similar to the aroma of Traminer pink. Sugar content of more than 24%. Vari-ety is designed for production for the dry white wines of excellent class and high-quality sparkling, dessert and sweet wines; suitable for the production of high quality aromatic juices
