The perfect flower has a unicarpellate pistil which consists of a globular ovary and a unilateral style.
Mango flowers are borne on terminal pyramidal panicles and are glabrous or pubescent; the inflorescene is rigid and erect, up to 30 cm long and is widely branched, usually tertiary, although the final branch is always cymose. Perfect flowers tend to be produced in largest numbers on the terminal portions of the panicle branches.
Flowering time is, closely link with the time of flower bud differentiation with variety and the area where it is grown.
The mango flower is adapted to insect pollination. Only small numbers of honeybees visit flower, so they are not important agents of pollination.
Temperature plays a key role in mango flowering and the response varies with cultivar. For flower induction, the ideal seems to be around 10-15° C.
Panicle growth does occur at 12.5° C, when no vegetative shoots s are produced.
However low temperature (less than 16° C) led to flower deformation, loss of pollen germination and slow pollen-tube growth and induce ovule abortion, with the production of seedless fruit.
