【Objective 】The proper shading rate and timing for Capsicum chinense Jacq. cultivation in tropical area were explored to provide references for its production in Hainan Province. 【 Method 】 Four shading rates of 30 %( T3), 50 %(T5),70%(T7) and 90%(T9) were set with no shading as the control to explore effects of different shading rate on Capsicum chinense Jacq. seedlings in summer and autumn in tropical area based on the analysis on morphological indexes,seedling index,chlorophyll content, soluble protein a...
