COMPARATIVE ANALYSIS OF ROOTSTOCK-VARIETY COMBINATIONS FOR TABLE GRAPE SAPLINGS

OpenAlex İngilizce

This study aimed to determine the vegetative features and total yields of tubed saplings obtained in viticulture application and greenhouse areas that belong to the Faculty of Agriculture, Dicle University, Turkey.Omega grafting technique was used to graft scion obtained table grape varieties (Razaki, Yalova Incisi, Hamburg Misketi, Italia, and Alphonse Lavellee, all belong to Vitis vinifera L.) onto six distinct American rootstocks (41B, 5BB, SO4, 420A, 5C, and 1613C).Two months after the grafted cuttings were planted in tubes for rooting in the greenhouse, shoot length (SL), leaf number (LN), and total sapling yield (TSY) parameters were investigated on the saplings.The statistical analysis revealed a significant difference at a 5% significance level for SL and LN between cultivar, rootstock, and cultivar × rootstock combinations.However, a significant difference was observed only at the rootstock level in terms of TSY.Depending on the rootstock and variety, the TSY ranged from 84% to 94%.On the other hand, the average LN per rootstock and cultivar was between 5.5 and 7.5, while the average SL ranged from 12.20 cm to 20.00 cm.
