Abstract

Spring wheat frequently subjected to high temperature damage,seriously affecting the yield and quality.In this study,spring wheat were plantd under the conditions of high temperature and studied the change of yield of starch formation.The results showed that daring wheat grain filling stage,amylase content increased and amyl pectin decreased,amylase/amyl pectin ratio increased significantly,total starch content and starch quality degraded.High temperature after flowering reduced starch content and yield.So,took a cultivation techniques to remit hazard of high temperaure after flowers could improve the yield of spring wheat in Ningxia,to a certain extent.
