INFLUENCE OF BIOEFFECTIVE PREPARATIONS THE INDUCTION OF GROWTH CORRECTIVE EFFECTS OF ROOTSTOCK GRAPE CUTTINGS AND GRAFTED QUALITATIVE SAPLINGS OUTPUT
The materials of long-term work on the study of the effect of drugs on the induction of growth-correcting effects for rootstock cuttings are presented. The research was carried out in Anapa-Taman area on the rootstock uterine plantation and the new plantation of AF «Uyzhnaya» of the Temryuk District of the Krasnodar Region, in the Center of Collective Use of FSCHVW (Krasnodar) and in the laboratory of nursery and quality control of Anapa ZESV&W. The task of the research is to find out the effect of plant nutrients in foliar top dressing the growth and development of cuttings as well as the dynamics of the processes of growth and development of grape saplings. The object of the study were the uterine rootstock plantings of the Kober 5BB variety, as well as grafted cuttings and saplings of the technical Aligote variety grafted on the Kober 5BB rootstock. As preparations were used: complex organic-mineral fertilizer and forth preparation with Zn, B, Fe, Cu apart. According to the set of regenerative activity indicators, the most effective drug for inducing the growth-correcting effects is «the variant of Boron», under the influence of which the objects of the study have the greatest indicators of shoots and roots development. This variant is better taking account the indexes of survival and getting of seedlings from the uterine grape plantations. Using the method of microfocus radiography, it was possible to establish that, on average, 90 % of seedlings have adhesions of grafted components without anomalies in all variants of experiment, which indicates the high quality of the obtained grafted saplings. The effective impact of bioeffective drugs the callus formation, the development of grafted cuttings in the first plantations, and the yield of grafted grape saplings is confirmed.
