Performance of improved aonla cultivars during top-working on senile trees

A study was conducted to rejuvenate sixty years old unproductive seedling aonla trees. Six improved cultivars viz., NA-6, NA-7, NA-10, Kanchan, Krishna and Chakaiya were top worked during June, 2001. Krishna showed better performance during top working by giving 77.77 per cent bud take followed by NA-10 and NA-7. However, minimum graft success was recorded in cv. Kanchan. The budding height also influenced the bud take and height more than 2.5 m from the ground reduced bud take considerably. The top worked trees started bearing after two years of budding and cv. NA-7 performed better than other cultivars.
