Anthesis
Anthesis is the period when a flower opens and functions in reproduction. A mango panicle contains many flowers that do not all open at exactly the same moment, so a flowering tree can present a changing mixture of buds, open flowers, and spent flowers. Weather and insect activity during this period can affect successful pollination. The term helps growers describe observations precisely without confusing first panicle emergence with the actual opening and reproductive activity of individual flowers.
