Title: Effects of Air Temperature on Head Development in Spring Wheat
Author: Black, A.L.; Bauer, A.; Frank, A.B.
Description: The head size of spring wheat is morphologically determined early in the growing season and can be strongly affected by air temperature. The materials and methods of a study are discussed. It was conducted to evaluate the effects of temperature stress, especially warm temperatures, on morphological development of the wheat head and the number of spikelets formed on the heads. The study included a determination of the effects of nitrogen levels and soil water available on head formation. The later are not included in this report. Air temperature does affect the duration of the apex vegetative and reproductive growth stages. Cooler weather prolonged such whereas warm shortened it.
