摘　　要：以黑农 4 0、黑农 4 1和黑农 37为材料 ,应用解剖学和电镜分析技术 ,对开花后始荚期 (R3)、结荚期 (R4 )、鼓粒初期 (R5)、鼓粒期 (R6 )、生理成熟期 (R7)等各期的豆荚进行观察 ,结果表明 :(1)大豆豆荚由外、中果皮和内果皮组成 ,其中前两部分与叶片相似 ,具有一套完整的光合作用结构系统 ,即外果皮的表皮与叶片表皮结构相似具表皮毛和气孔 ;整个中果皮由 10余层薄壁细胞组成 ,内含叶绿体 ,为同化组织 ,在同化组织中间分布着发达的输导组织系统 ;(2 )随着豆荚的生长发育 ,同化组织的形态、大小及叶绿体的超微结构发生有规律的变化。We have observed photosynthetic structure system of soybean pods,on Heinong 40, Heinong 41 and Heinong 37 at R 3—R 7 stages by means of light microscopy and electron microscopy. The results indicated (1) exocarp and mesocarp of soybean pods consisted of complete photosynthetic structure system, which was similar to that of leaf. Structure of exocarp was also similar to that of leaf in surface hairs and stomata. Mesocarp, assimilation tissue, were made of more than ten layers parenchyma cells that content chlorophyll and there are some strong conducting tissue in it. (2) The assimilation tissue and chlorophyll in it with soybean pods growing, for example, assimilation tissue's form, size and ultrastructure were changed.
