The phenomenon where the androecium (male reproductive organs) and gynoecium (female reproductive organs) of a bisexual flower mature at different times is known as Dichogamy. In dichogamous flowers, the male and female reproductive structures are temporally separated, which helps to prevent self-pollination and promotes cross-pollination. This temporal separation can occur in different ways, such as protandry (maturity of stamens before the pistils) or protogyny (maturity of pistils before the stamens). Dichogamy is an important mechanism in plants to enhance genetic diversity and promote outbreeding.
