Hormonal approaches in floral induction of mango
Author(s): G Chandramohan Reddy and Sweety
Abstract: Mango exhibits a wide variation in flowering and fruiting habit due to varietal differences and diversity in agro-climatic conditions. Floral induction in mango is not once off happening, but rather a continuous process lasting during the early stages of bud differentiation. There are some correlative evidences for regulation of floral initiation in mango by plant growth regulators, GA, PBZ, Ethylene, Cytokinin, TIBA etc. PBZ could promote flowering in two ways by speed up and increase the synthesis of the floral stimulus in an inductive cycle and by affecting the ratio between flowering promoter and flower inhibiting promoter. Spraying of 500-1000 ppm ethephon and 100 ppm benzyl amino purine one month before the normal flowering resulted early bud break and increased flowering in mango. As a final consequence of efforts to elucidate the mechanisms of floral induction in mango becoming clearer at the hormonal balances play a major role in mango flowering and fruiting. Application of growth regulators in right dosages on and off year of crop helpful for getting good crop with excellent quality.
