Tikhomirova N. Development of the way of dush re-grafting for effective technological and high-quality reconstruction of operational grape plantings

The dissertation is devoted to the way of perennial bush regrafting for the replacement on the operational grape plantings of low-productive species, negative clones and stock bushes by high-quality species meeting the requirements of production. The developed ways of grafting allow to simplify the performance technique, to increase productivity and striking root, and also to improve the quality of accretion of grafted components due to the choice of the optimum place for grafting. On the culture of Muscat white, the most suitable ways of grafting for a long-term bush are determined. Due to grafting "updating" the upper part of the bush is established to take place. Grafted plant due to the generated root system has a sufficient stock of nutrients for more intensive development than a young bush in the first years after planting. According to striking root of grafted components there is allocated inoculation as perspective ways of grafting. On the productivity there allocated inoculation as a way of grafting. It is established that in the third-fourth year of vegetation the majority of bushes achieve a final degree, have strong growth of shoot and enter partial and full fructification.
