Effect of low temperature on growth and development of wheat and response mechanism

Abstract

Low temperature is one of the important environmental factors affecting plant growth and development and yield formation. Wheat is an important food crop in the world, and the annual low temperature causes huge losses to plant yield. Therefore, cold resistance has always been an important research field in agricultural production and breeding. Wheat is mainly divided into winter frost damage, early spring frost damage, low temperature freezing damage, etc. The effects of freezing damage on wheat yield in different periods are different. This paper mainly introduces the influence of low temperature on its morphological development and yield formation, as well as the research progress in physiological, biochemical and molecular biology. Finally, it points out the shortcomings in the research and looks forward to the future research direction of low temperature
