EFFECT OF DIFFERENT EXOTIC AND INDIGENOUS APPLE ROOTSTOCKS ON THE GRAFT SUCCESS OF SCION CULTIVAR ANNA

Abstract

An experiment was conducted to find out the effect of different apple rootstocks on the graft success of apple cultivar Anna. According to the experimental results maximum plant height (204.62 cm), root thickness (63.21 mm), root weight (308.03 g) and root length (18.40 cm) were noted in crab apple rootstock, maximum root top ratio (0.48), lodging (12.00%), number of nodes per plant (87.89) and number of leaves per plant (322.33) were observed for MM-111 rootstock and maximum stem weight (1103.8 g), number of shoots per plant (16.11), sprouting (93.66%), number of roots per plant (40.55) were recorded for EM-7 rootstock, while minimum number of roots per plant (28.83), plant height 150.71 cm), (plant girth 68.23 cm), number of nodes per plant (67.22), number of shoots per plant (9.22) and stem weight (571.79 g) were recorded for EM-27 and minimum number of leaves per plant (230.2), root thickness (22.4 mm) and root weight (246.71 g) were noted for MM-106 rootstock. Crab apple, MM-111 and EM-7 root stocks offered excellent response to Anna cultivar of apple.
