Abstract: ‘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.
