Effects of high temperature during anthesis and grain filling on physiological characteristics of winter wheat cultivars

چکیده
Due to climate change, multiple heat events are expected be an additional limiting factor that will adversely affect wheat production. The study aimed analyze the physiological response stress in four winter cultivars at different stages under greenhouse conditions during 2019. net photosynthetic rate, stomatal conductance, chlorophyll index, maximum quantum efficiency of photosystem II, fructose, glucose and sucrose content, grain yield per plant, weight number grains plant were analyzed short periods anthesis mid-grain filling, combined filling. results indicated modified photosynthesis-related yield–related traits. Moreover, caused a decrease while fructose content increased. Heat had more pronounced effects on parameters filling than anthesis. A significant variation observed among cultivar responses negative impact highlighted fact Pobeda Gladius tolerant Renesansa Simonida. Different reactions need conduct further studies with origin order identify sources tolerance.
