Abstract

The effects of different concentrations of exogenous abscisic acid(ABA) and calcium chloride(CaCl2) on eggplant seedlings under low temperature stress were studied.The results showed that the resisitence with 10 mg/L of ABA and 1 000 mg/L of CaC12 was the best,the chilling injury index decline significantly.Spraying exogenous substances could significantly reduce the relative conductivity and MDA content,increased chlorophyll content and photosynthetic rate,improved the content of protection enzymes and chloroplast membrane ATP enzyme,eased the chilling injury.
