Content Guidelines 2. of maize seed. In both maize and Eastern gamagrass, the unisexuality of florets is established through a process of selective elimination or maturation of preformed floral organs in an initially bisexual immature floret (1, 3). The ovary is one-chambered, superior, ovoid in shape with a single anatropous ovule. Germination is hypogeal. The kernels (there can be around 400 - 1000 on each ear) are attached to a cob and enclosed by layers of leaves. The arrange­ment is distichous or 2-ranked. 6 7.

The male inflorescences are on terminal branches and the female inflorescences are lower down, on lateral branches. It is a pest of stored maize, dried cassava, yam, common sorghum and wheat. In maize, this occurs when the vegetative shoot meristem ceases leaf initiation and becomes consumed in the production of the tassel inflorescence primordium.
