Abstract : In both biennial (Dashehari, Langra and Alphonso) and regular bearing (Neelum and Kalapady) mango cultivars, there was a progressive reduction in fruit size with decreasing numbers of supporting leaves. In regular bearing cultivars, more than 50 leaves were needed for normal fruit growth if fruit growth depended upon current photoassimilates. Both regular and biennial bearing cultivars utilized reserve photosynthates in addition to current photosynthates for normal fruit development. A large quantity of carbohydrate depletion during on years is one of the factors responsible for biennial or alternate bearing in mango.
