| Abstract: | Two types of winter wheat(Triticum aestivum.L),including dryland cultivar Changwu 134 and irrigated land cultivar Shaan 253,were selected to study the effects of soil drought on starch accumulation of grain and activity of corresponding starch synthesis enzymes,and then to elucidate some physiological mechanisms of wheat grain filling under soil drought condition.The results indicated that soil drought could significantly increase the starch accumulation rate and SS,AGPase,UGPase,SSS and GBSS activity of gr... |
