Evaluation of Vegetative, Quantitative and Qualitative Traits of Two Apple Cultivars on MM106 Rootstock and Seedling Rootstock
In this study, vegetative, quantitative and qualitative traits of Red Delicious and Golden Delicious cultivars on MM106 rootstock and seedling rootstock were studied factorially in a completely randomized design. Flowering onset, number of flowers, dropping, yield, fruit size, L/D, total acid, vitamin C, soluble solids, percentage of dry weight and branch and trunk growth were examined as variables. Regarding the climatic condition of the region, the onset of flowering in the cultivars tested was almost simultaneous so that there was a slight difference between them. The results showed that Golden Delicious cultivar on MM106 rootstock had the highest percentage of flowering and flower density. The percentage of first dropping and June dropping in golden delicious was higher than red delicious; However, pre-harvest dropping was higher in Golden Delicious. The results showed a significant increase in dropping at seedling rootstock compared to MM106 rootstock. The MM106 rootstock increased the yield. The rootstock had a significant effect on fruit size and weight. Red Delicious cultivar showed a heavier weight. Fruit acidity was higher in seedling rootstock than MM106 rootstock but total sugar, Tss, vitamin C and dry weight percentage were higher in MM106 rootstock. Soluble solids did not differ significantly between cultivars. Red Delicious cultivar had the highest branch growth and trunk diameter in terms of growth.
