Bud morphology and expression of floral malformation in mango (Mangifera indica)

Studies were conducted to find out the association of morphological characters associated with floral malformation in Dashehari and Amrapali mango at Division of Fruits and Horticultural Technology, IARI, New Delhi, during 1993–95. Simple (solitary apical) and multiple (apical and auxiliary buds with several protuberances at their bases) floral buds were tagged at bud swollen and bud-burst stages and incidence of malformation in these buds was recorded at the time of flowering. Data revealed that multiple buds gave higher proportion of malformation at both the stages in Dashehari (60.96 and 62.08%) and Amrapali (94.84 and 88.78%) compared to simple buds (20.24, 19.68%, 14.46, 9.03%) in both the cultivars respectively. In most of the cases, it was found that malformation incidence was more with increasing diameter of buds. Length of simple and multiple buds did not show correlation with incidence of floral malformation.
