| Among the agronomically important grasses, maize is the most susceptible to drought at flowering. Drought stimulates a protandrous pattern of development, increasing the anthesis-silking interval. Because maize has a short period of flowering and pollen remains viable for only a short period of time, each day of delay between pollen shed and silk emergence will reduce the rate of sexual fertilization and increase barrenness. The purpose of this article is to present an ideotype of maize designed to overcome this problem. The biological model described here can reduce sensitivity to water deficiency through morphological and anatomical modifications, such as the transference of the ear from the axil of a leaf to the apex of the plant; condensation of the... |
