Abstract:
Taking ‘Hangqie No.1’ as material，the eggplant seedlings in the sun-shading screen with different shading rates (30%，50%，70%，90%) were set，compared with no shading in the rain shelter，the effect of different shading treatments on morphological indexes，physiological indexes and photosynthesis parameters of eggplant seedlings in the summer and autumn in the tropics were studied.The results showed that，the morphological indexes，seedling indexes，chlorophyll contents，soluble protein and soluble sugar content of the eggplant seedlings were declined with the shading rate increased，the control was significantly higher than other treatments，membrane permeability and MDA content of 30% shading treatment and CK were lower than that of other treatments，and the photosynthetic parameters showed that shading too much light would decrease the Pn of the eggplant seedlings，however，the Pn of the eggplant seedlings of CK decreased in 12:00～14:00.In conclusion，the eggplants seedlings in the rain shelter only need by 30% shading net at noon.
