Abstract

Abstract: By using pepper 9024 of thick trichome as material,distribution pattern of trichome character at seedling stage and photosynthesis indexes were studied. The results showed that,during its different growth period at seedling stage,trichome density of its first leaf,leafstalk and stem segment had obvious difference,with the greatest density at one and a half leaves stage and at seven and a half leaves stage,the nearer of the leaf to the growing tip,the greater density of trichome. When comparing photosynthesis indexes,though lesser than two kinds of eggplant,net photosynthetic rate of pepper 9024 was larger than those 4 kinds of pepper on significant level,and its greatest rate was 21. 2 μmol /(m²·s), indicating its big potential of breeding for poor light adaptability and high photosynthetic efficiency.

Key words: Pepper, Trichome, Net photosynthetic rate
