Abstract

n this research, the qualitative and quantitative characteristics of red delicious and golden delicious cultivars on MM106 and seedling rootstocks were studied. The experiment was conducted in a completely randomized factorial design with five repetitions. Golden delicious cultivar on MM106 rootstock has the highest percentage of flowering, flower density and fruit’s number. June drop was more in golden delicious cultivar than red delicious cultivar but the preharvest drop was more in the red delicious cultivar than golden delicious cultivar. Results indicate the significant increase of drop in seedling rootstock in contrast to the MM106 rootstock. MM106 rootstock increased significantly the amount of product in contrast to the seedling rootstock. The acidity amount of fruit was more in the seedling rootstock rather than that of the MM106 rootstock, but the amount of total sugar, TSS, vitamin C and percentage of dry weight were more in the MM106 rootstock rather the seedling rootstock.
