High temperature(HT),drought stress(DS)and their combination(HT+DS)after anthesis affected the starch concentration and its components as well as the starch characteristics significantly in wheat grains.A pot experiment was performed at the scientific &educational station of Henan agricultural university in 2014-2015 wheat growing season.Luomai 24 and Zhengmai 366,wheat cultivars with different gluten-strengths,were grown in 24 cm pots with 10 kg loam soil.The experiment was arranged with a completely rando...
the decrease of final starch accumulation quantity.Compared with the CK,the concentration of amyl-opectin and total starch were all decreased significantly under stress treatments,the amylose was lesssensitive to the stress treatments,which led to an incr
