Technological parameters of the introduction of grapes into the in vitro culture have been improved. The use of growth regulators (6-BAP, 2iP, kinetin) contributed to the enhancement of rhizogenesis and an increase in the coefficient of in vitro plant reproduction. New methods for adapting grape plants that were in vitro improved to in vivo conditions at the reproduction stage have been studied. It has been shown that all concentrations of lingo-humate had a positive effect on plants, which in turn contributed to ...

The development of the most efficient technology is extremely important to synchronize work on the laying yielding strawberry parent plants. The main link here should be the material obtained in vitro. The most vulnerable element of in vitro technology is adaptation to non-sterile conditions, when it is very difficult to simultaneously control a large number of factors and when very large plant losses are possible. The fundamentally new method of adapting microplants to hydroponics has been tested and allows us to...

Studies were conducted in an intensive fruit-bearing apple orchard in the South of Russia in the Chechen Republic. Layout scheme - 3,75?1,5 m, the formation of trees - a slender spindle. The object of study were apple cultivars Renet Simirenko (control), Granny Smith, Florina (M9). The main soil cultivation (autumn plowing) was carried out once in 3-4 years by garden plows or plows-lushmen at a depth of 14-16 to 18-20 cm in row-spacing and 6-12 cm in the trenches. Cropping blocks in an intensive garden with dwarf ...

Modern viticulture of Russia should be based on the production of certified planting stock. The production of planting material of the highest categories in the Russian Federation is absent. The main goal of the research was to improve the technology of clonal micropropagation using growth regulators. The task was to obtain a healthy planting stock of grapes and to introduce a certification system for planting material according to the pattern of European countries. The object of research were complex-resistant va...

The effect of different doses and time of boron fertilization on growth and development of grape plants were studied on the soils of Terek-Kumskiy sands of Chechen Republic, Russian Federation. The aim of research is to study the content of boron in the soil and to identify the physiological response of the vine plants on boron fertilizer. The obtained data of the boron total content in the studied sandy soil showed that in 0-60 cm layer of the soil the boron total content ranges from 0.4 to 0.5 mg/kg, in 60-150 c...
