Zinc and growth substances—NAA and 2,4-D, were applied on Purbi cultivar of litchi to study the effects on the development and quality of fruits. The results show that 1.0 per cent zinc was effective in enlarging the volume of fruits. Marked effect in enlarging fruit volume was observed with NAA at 10 ppm. Both zinc and growth substances were found effective in improving the internal quality of the fruits in respect of total sugars, acidity and ascorbic acid contents.
