I had already mentioned before, that corn plants from the time the seeds are sown until the appearance of the first sprouts, a certain time of less than a week elapses, where the continuous and rapid growth of the seedling is very reflected, the roots are fasciculated and their mission is to provide a perfect anchorage to the plant.
▶ However, tillering can be an advantage in the case of forage maize. Some varieties of sweet corn and pop corn produce tillers, some of which can be productive. The anatomy of the leaf and stalk of corn has been described in detail, for example, the stalk has three important components in its tissues: the cortex or epidermis, the vascular bundles and the pith. The vascular bundles are arranged in concentric circles with a higher density of bundles and rings closer to the peripheral epidermal zone; their density is reduced towards the center of the stalk.

The higher concentration of vascular bundles below the epidermis provides the stem with resistance against tipping, comparisons have been made under field conditions, the stem anatomy of several pure lines differing in tipping. The lines with stronger stems had more layers of thick-walled sclerenchyma beneath the stem epidermis and also around the vascular bundles.
Maize is a monoecious plant; it develops inflorescences with flowers of only one sex, which always grow in separate places on the plant. The female inflorescence or cob grows from the apical buds in the leaf axils and the male inflorescence or panicle develops at the apical growing point at the top of the plant. Initially, both inflorescences have bisexual flower primordia; during the development process the stamen primordia in the axillary inflorescence abort, leaving only the female inflorescences.
Similarly, the gynoecium primordia in the apical inflorescence abort, leaving only male inflorescences. Sex determination in maize is a complex process involving an interaction between genetic determinants (masculinizing and feminizing genes), environmental determinants, gibberellins and steroid-type plant hormones.
