Floral induction in axillary buds of mango (Mangifera indica L.) as affected by temperature

The effect of temperature on flower induction of axillary buds of 3-year-old ‘Haden’ mango trees was studied. The trees were de-blossomed by pruning the stems 5 cm below the base of distal panicles and exposed to 3 temperature regimes (, and ) in 8 treatments under a 12-h photope Axillary flower induction was greatest on the mango trees subjected to the low-temperature treatment of for 2 or more weeks. The subsequent temperature following 1-week exposure at also influenced the number of axillary buds to develop. A negative relationship existed as the number of axillary buds increased as the temperature decreased. The flowering percentages of the plants treated at , and were 87, 60 and 0, respectively, when the temperature was held constant. The physiological condition of the plants may also be a critical factor in the flowering induction sequence of mango
