摘 要 ：以12个生育期和结荚习性不同的夏大豆品种（系）为材料，测定其在不同条件下青壮龄（展开13日龄）叶片和幼龄（展开4日龄）叶片的光合速率。结果表明，在晴天、适宜供水和自然光照下，夏大豆青壮龄叶片的光合速率（y）与光强（x）呈极密切的正指数曲线关系x=aeby，光合速率随光强增强而升高，没有“午休”现象。幼龄叶片在低

Abstract:Soybean [Glycine max (L.) Merr.] is a C3 species with low photosynthetic rate and low photo saturation point, and has Noontime Snooze of photosynthesis. It was suggested that higher light intensity was the main reason that caused photosynthetic rate decline and Noontime Snooze of photosynthesis in s
