Abstract:

The objective of this study was to investigate the effects of drought stress during filling period on starch accumulation in sorghum. Two sorghum varieties, Tieza17 (high starch content) and Liaoza11 (low starch content) were planted in pots as the experiment materials. The two varieties were suffered from drought stress at initial stage, middle stage and late stage of grain filling period, respectively. The starch content, amylose content, amylopectin content and grain yield of the two sorghum varieties were investigated. The results showed that the contents of starch, amylose and amylopectin and grain yield were decreased by drought occurred at filling period. The effects of drought stress on starch accumulation at different stages of grain filling period were mainly at the initial filling stage > the middle filling stage > the late filling stage. Tieza17 was more sensitive than Liaoza11 to the drought stress. The variable coefficients of starch indexes under drought stress was as follows: amylose > amylopetin to amylase ratio > total starch > amyloptin, indicating that amylose was more susceptible to drought stress than amylopectin. Generally, drought stress during filling period significantly influenced the starch accumulation, resulting in decrease of the 1000-seed weight, ultimately caused a decline of grain yield in sorghum.

Key words: Sorghum, Filling period, Drought, Starch
