摘　　要：以“华研5号”茄子为试材,采用基质栽培法,研究了不同逆境(干旱、高温、盐胁迫)处理下茄子的维生素P、可溶性糖、可溶性蛋白质和花青素含量等品质指标变化,以期为生产优质茄子提供参考依据。结果表明:150 mmol·L^(-1)低盐胁迫可以提高茄子果实的维生素P含量,降低花青素、可溶性蛋白质和可溶性糖含量;10%PEG 6000轻度干旱胁迫能够提高果实的维生素P、可溶性蛋白质和花青素含量升高,降低可溶性糖含量;40℃高温胁迫可以提高茄子果实的维生素P和可溶性蛋白质含量,降低花青素和可溶性糖含量。‘H5'eggplant was used as test material.The substrate cultivation method was used.The quality indexes such as vitamin P,soluble sugar,soluble protein and anthocyanin content of eggplant under treatment were studied after different adversity(drought,high temperature and salt stress)treatments,in order to provide reference for the production of high quality eggplant.The results showed that 150 mmol·L^(-1)low salt stress could increase the vitamin P content and decrease the anthocyanin,soluble protein and soluble sugar content of eggplant fruits;10%PEG 6000 mild drought stress could increase the vitamin P,soluble protein and anthocyanin content and decrease the soluble sugar content of fruits;40℃high temperature stress could increase vitamin P and soluble protein content and decrease anthocyanin and soluble sugar content in eggplant fruits.
