Abstract : An experiment was conducted in Bangalore, Karnataka, India, during 2000-02 on 4-month-old uniform mango seedlings raised in polythene bags to assess the effect of bark inversion treatment on the growth, vigour and graft success of mango seedlings during initial stages of graft growth. Three mango cultivars were used, namely Bappakai, Olour and Alphonso. The bark inversion treatment effectively induced the attributes essential for inducing dwarfing of mango plants in initial stages of graft growth compared to the control (without bark inversion) plants. The minimum plant height (7.8 cm) and sprout length (2.1 cm) were recorded in Olour due to bark inversion, whereas in grafts without bark inversion the values were 12.6 and 6.3 cm, respectively. The highest graft success (59.2%) was recorded in Olour without bark inversion, whereas Alphonso with bark inversion recorded the minimum graft success (45.1%).
