摘　　要：采用光合速率不同的大豆品种黑农 37(普通高产品种 )、黑农 4 0和黑农 4 1(高光效品种 ) ,分别于R3、R4 、R5、R6 和R7时期取荚进行了解剖学观察。结果表明 :1.不同光合类型品种间 ,豆荚表皮上气孔密度彼此接近 ,无明显差别 ;2 .豆荚同化组织细胞内叶绿体数目 ,高光效品种均大于普通高产品种 ,且在相同品种中豆荚叶绿体分布的密度为豆荚的两端大于豆荚的两面。在R6 时期叶绿体的体积高光效品种也大于普通高产品种。叶绿体中基粒的数目也是如此 ;3.豆荚两侧维管束密度以及腹。Soybean varieties, Heinong 37(with high yield), Heinong 40 and Heinong 41(with high yield and high photosynthetic rate) were used as materials in this experiment. The anatomy of pods from R 3, R 4, R 5, R 6 and R 7 stages was conducted. The results show that: (1) The density of stomas on pod wall is similar among different types of varieties. (2) The number of chloroplasts in assimilative cells of pods is bigger in varieties with high potosynthetic rate than in common varieties with high yield. The distribution of chloroplasts in one pod is more in both sutures than in both sides. (3) The size of chloroplasts and the number of grana in them at R 6 stage are bigger in varieties with high photosynthetic rate than in common varieties with high yield. (4) In varieties with high photosynthetic rate, the density of vascular bundles in both sides and the number of vessels in both sutures of the pod are bigger than in common varieties.
