THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS
06.00.00 Agricultural sciences
DescriptionVitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection

EXTRACTION OF DNA FROM HERBARIUM LEAVES VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionTwo methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA

OUT-OF-ROOT FEEDING AS THE WAY OF INCREASING OF ADAPTABILITY OF WINE PLANTS TO SANDY SOILS
06.00.00 Agricultural sciences
DescriptionResults of research of influence of foliar top dressings by Zitovit and Zircon preparations on development of plants of grape of Berlandieri × Riparia Kober 5ВВ grade on sandy soils are submitted. Processing of plants with Zitovit in conditions of their insufficient mineral nutrition through roots, improved their growth and development. Action of Zircon preparation for raising immunity promoted qualitative rearrangement of morphological parameters of development of plants
