Abstract
Current study was conducted to evaluate the effect of quince A and hawthorn rootstocks on some morphological and pomological properties on the Esfahan local quince cultivar based on completely randomized design with 32 tree. The effects of quince A and hawthorn rootstocks were evaluated based on tree height, internode distance, shoot growth, average of fruit's size, weight, diameter, and length, percentage of dry matter, percentage of fruit juice, fruit color, fruit and leaf chlorophyll, TSS and total flavonoids of fruit. The results showed that the height of tree on hawthorn was less than quince A, the weight (317.5g), size (374.3 cm3), length (81.90 mm), and diameter of fruit (86.53 mm) were more than it, and the percentage of fruit juice (86.26), carotenoid of skin (3.056 mg/gFW) and were more. According to results of this study, it can be suggested that hawthorn rootstock can be as a dwarfing rootstock that leads the quality of fruits to increase. A positive correlation among tree height and shoot growth, flavonoids of total fruit, percentage of dry matter and TSS were observed. On the other hand, there was a negative correlation among tree height, and average of fruit's size, weight, and diameter, percentage of fruit's juice, internode distance. In some cases like fruit color there was no significant difference with tree height and other characteristics. According to the results of the present research, hawthorn rootstock can be suggested as a suitable dwarfing rootstock that increases quality of the fruit.
