摘要
利用光学显微技术和扫描电镜技术，对大豆属ClycineL.的4种类型植物茎材进行比较解剖学研究．结果表明，4种类型植物的茎材横切面均为散孔材。野生大豆茎材多为单管孔．少见复管孔；半野生大豆具复管孔，少见多细胞的管孔链；半栽培大豆茎材中复管孔和管孔链较多；而栽培大豆的复管孔和管孔链更多且普遍．野生大豆单列射线多，多列射线少半野生大豆有少数多列射线；半栽培大豆多列射线较多；栽培大豆多列射线细胞组成的射线最多．大豆种植物的次生木质部导管的侵填体分布不同，各种结构的演化途径为野生大豆→半野生大豆→半栽培大豆→栽培大豆野生大豆结构较原始。
Optical microscopic and scanning electron microscopic studied on the comparative anatomy offour type stem woods of soybean (Glycine L. ) show that all of them are the diffuse-poruswoods. There are a lot of solitary pores and seldom multiple pores in the secondary xylem ofwild soybean (G. soja ). Semi-wild soybean has multiple pores and seldom multi-celled porechains. There are many multiple proes and pore-chains in the secondary xylem of semi-culturedsoybean. Cultured soybean (G. max) has more multiple pores and pore-chains than otherspecies of soybean. G. soja's wood rays consist of unseriate ray and seldom multiseriate ray.They are more multiseriate rays in scmi-wild and scmi-cultured soybcans. The largest numberof multiseriate rays is in G. max. The distribution of tyloses in the vessels of secondary xylemis different among the four species of soybean. The structural evolutionary approach is G. soja→semi-wild soybean→semi-cultured soybean→G. max, indicating that G. soja is primitiveand G.,max. is most evolutionary.
