Abstract
As a monoecious plant, maize develops unisexual male and female flowers in physically separated parts of the plant. The tassel (staminate or male inflorescence) arises from the shoot apical meristem, while the ears (pistillate or female inflorescences) originate from the axillary bud apices. Initially, both inflorescences contain bisexual flowers. During the course of development, however, they become unisexual through abortion of gynoecia in the tassel flowers and stamens in the ear flowers. As a result, the tassels develop male flowers and the ears develop female flowers.
