| Abstract: | Engrafted cuttings of the variety Rkaciteli on stocks B?×?R Cober 5BB and R?×?R 101-14, having endured open and covered stratification on different substrates, were planted in a polyethylene glasshouse on four artificial substrates after the postplanting preparation. The complex effect of the stock variety was examined, as well as the effects of the stratification methods and the substrates on the yield of engrafted vines. The characteristics of the regeneration of the engrafted cuttings during the stratification were established. The optimal substrates for stratification of the transplants and the growing of engrafted vines in glasshouses were defined. |
