摘　　要：研究了外源喷施不同浓度脱落酸(ABA)和氯化钙(CaCl2)对低温胁迫下茄子幼苗抗冷性的影响。结果表明:茄子幼苗外源喷施10mg/L ABA和1 000mg/L CaCl2效果最好,能够使茄子的冷害指数显著下降。喷施外源物质能够明显降低茄子幼苗的相对电导率和丙二醛含量,提高叶绿素含量和光合速率,提高保护酶和叶绿体膜ATP酶含量,对冷害具有缓解作用。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.
