Seedling production technology improvement for viticulture covering zone

The intensification of the most important branch of agriculture in the Russian Federation – viticulture – in the new conditions of market relations should be based on the use of new scientific developments, which include not only the replenishment and improvement of new grape varieties, but also the technology of their cultivation. A new method has been developed for the formation of seedlings for the covering zone in the conditions of the Rostov Region. The cultivation of vineyards in the cover zone is associated with a high laboriousness of work. In this regard, an intensification of the technology for the production of grape seedlings with a ready-made horizontal sleeve was carried out under the influence of graviomorphological stimulation. The new technology for the production of seedlings is based on a change in the arrangement of cuttings during their stratification. This method allows you to get grape plants already with a ready-made horizontal sleeve and plant them 10 rows in one direction and 10 rows in the other. With this method of planting grape plants when bushes are mechanically covered and open their injuries reduce. Also, experimentally, additional new data were obtained that characterize the features of the regeneration of grafted grape seedlings during stratification and growing them at an angle of 30°. The formation of a horizontal sleeve in a grafted grape plant under the influence of graviomorphological stimulation creates a certain configuration for the assimilation of photosynthetic active radiation and makes it possible to increase the safety of plantings during covering and opening. This method of growing seedlings contributes to a more intense callus formation, which helps to eliminate the gap in the scion-rootstock components of the graft.
