Trees start flowering and fruiting 2-8 years after planting. Flower and fruit loads are initially low and improve with increasing size and age; trees 2years old produce about 25 flowers and 3 fruits; trees 5 years old bear asmany as 840 flowers, and trees 6 years old 1500 flowers. However, only15-18 fruits develop due to the low production of female spikes (about 0.6-5% of the total number of inflorescences). Young trees bear more malethan female flowers at a ratio of 4:1; production of female flower increaseswith age. A male-to-female ratio of 2:1 produces 250 fruits per tree, and asthe trees ages, fruit productivity declines.In suitable environments trees bear fruits and flowers throughout the year,but in areas with distinct dry and wet seasons, flowering occurs in the wetseason. In young trees, fruits are usually borne on branches and in oldertrees, on trunks and roots.The tree is wind and insect pollinated. Insects normally visit the scentedmale flowers, which release pollen that is carried to female flowers by thewind. Wilting and drying stigmas are the best indicators of fruit set. Fruitsmature in 80-160 days, and a sweet and strong aroma indicates that thefruit is ripe.
