Abstract

Using the major pepper cultivar Longjiao No.2 for heliogreenhouse planting in Hexi corridor of Gansu, we studied the effects of spraying exogenous ALA on improving drought stress of pepper seedlings in pots by controlling water usage. The results showed that, compared with the control treatment(spaying clear water), spraying exogenous ALA could significantly improve the soluble sugar content, chlorophyll content, SOD activity and POD activity, and lowered MDA content, which indicated that spraying exogenous ALA could improve the drought resistance of pepper seedlings.
