In maize, this occurs when the vegetative shoot meristem ceases leaf initiation and becomes consumed in the production of the tassel inflorescence primordium. The floral transition is a critical developmental change in a plant's life cycle that is marked by the switch from vegetative to reproductive growth. Maize was originated from its Mexican variant called teosinte. seed should be covered by 1-1 1/2 inches of soil to allow for adequate root system to develop.

The parthenocarpic fruits are formed from ovary without fertilization. A Genomic and Expression Compendium of the Expanded PEBP Gene Family from Maize. In contrast to its wild ancestor, modern maize shows a large geographic distribution from 0 to 50 N. Adaptation to temperate latitudes, with long days during summer, required breeders to first suppress the short-day requirement for floral induction, but a second adaptation was also required.
