Quick Summary

Protogyny is a botanical term describing a state in hermaphroditic plants where the female reproductive organs mature before the male ones. This temporal separation, known as dichogamy, inhibits self-fertilization and promotes cross-pollination.12

This phenomenon is observed in various plants, including apples, pears, and figworts. It is the opposite of protandry, where male organs mature first. Protogyny ensures that pollen from one flower is unlikely to fertilize its own ovules, encouraging genetic diversity within the species.12

Protogyny, the situation in which the pistils mature first, occurs in arum lilies and many wind-pollinated plants, such as grasses—although several grasses are self-pollinated, including common varieties of wheat, barley, and oats. Avocado has both protogynous and protandrous varieties, and these often are grown together…
