Abstract : Mango cv. Manila trees growing at 2 sites in Mexico under different temperature conditions were studied to determine the degree days (DD) and base temperature (Tb) required for inflorescence elongation (bud break to fruit set) and fruit development (fruit set to maturity). The values calculated for inflorescence elongation were 434.7 DD above Tb of 12°C and for fruit development 2292.7 DD above 0.33°C. Tb was a better predictor of DD than figures previously used for mango. Tb and DD were calculated for normal flowering dates and for early flowering induced by KNO3 or NH4NO3.
