 "Flowering begins at 4-6 years of age; trees begin to bear at 7-8 years, reach full bearing at 10-15 years, continue to yield until ca. 40 years, then persist in a sterile state until death. The first inflorescences may contain only male flowers and consequently do not produce nuts. A mature tree in full bearing can have inflorescences containing up to 644 female and 15-48,000 male flowers (Murthy 1977). The male flowers open first. Their sweet scent attracts honeybees and other insects, but these insects do not frequent the female flowers and thus their role as pollinators is doubtful.
