Abstract:   (466 Views)

In the present study, the effects of four quince rootstocks Quince A, B, C and BA29 were compered with Gonjuni and pear seedling in combination with Shah Miveh, Natanzi and Sebri cultivars. At the end of growing season, growth traits and after fruiting, yield and quality of fruits in each rootstock and cultivar combinations were noted. The results showed that the factors of year and rootstock and their interaction had significant effects on the evaluated traits. The highest rootstock diameter (10.4 cm), cultivar diameter (10.6 cm), grafting :::union::: (10.7 cm) and tree height (240.7 cm) was observed in grafting combinations of cultivars with Gonjuni and pear seedling rootstocks. The lowest growth in diameter of rootstock (6.4 cm), cultivar (6.97 cm) and grafting :::union::: (8.1 cm) was observed in combinations between cultivars with Quince A, B and especially Quince C. Cultivars on Gonjuni and pear seedling rootstocks had the highest annual growth (63.1 cm). All three cultivars on Quince rootstocks induced less vegetative growth to tree. Cultivars on quince rootstocks had more yield, and yield to trunk cross sectional area compared with yield and yield to trunk cross sectional area in seedling rootstocks. Vegetative growth and bearing had negative correlations. Rootstock also affected qualitative traits of fruits, so that quince A, B, C and BA29 rootstocks in addition to the induction of precocity, affected other fruit Quality characteristics such as fruit ripening time, fruit uniformity, symmetry, fruit size, flesh quality and fruit marketability. All grafting combinations on Quince rootstocks were compatible excluding Shah Miveh and Natanzi on Quince B.

Keywords: Pear, seedling rootstock, clonal rootstocks of quince, interaction between rootstock and cultivar.
