Question

why do androecium and gynoecium of same flower matures at different times

Answer 1

• In a bisexual flower, when the male reproductive part ‘androecium’ and the female reproductive part ‘gynoecium’ matures at different times, the phenomemon is referred as ‘Dichogamy’.
• This condition occurs in order to avoid self-pollination.
• Flower arrangement pattern (inflorescence) and other physiological barriers may affect the the time at which the androecium and gynoecium matures in the same flower.

Answer 2

To prevent self pollination to help in cross pollination, androecium and gynoecium develop at different times. The condition is known as dichogamy.

Definition of dichogamy. : the production of male and female reproductive elements at different times by a hermaphroditic organism in order to ensure cross-fertilization.
