摘要: 利用光学显微镜,对大豆属(Glycine L.)中的不同进化型大豆花的结构进行了比较研究.结果表明,野生大豆(Glycine soja)蝶形花冠中的2枚龙骨瓣分离,筒状花萼的解剖结构中没有组织分化.栽培大豆(Glycine max)蝶形花冠中的2枚龙骨瓣完全愈合成为一体.花萼结构由表皮和无规则的薄壁细胞组成,在薄壁细胞间等距分布细小的退化维管束.2种大豆花的花瓣存在明显差异.可以认为,在进化程度较高的两侧对称的蝶形花冠的大豆属中,仍然保留有原始花的结构特征.

Abstract: Optical microscopic study shows that there exists a significant difference of floral structure between G. soja and G. max. For G. soja. its papilionaceous flower has two separated dragonbone petals, and tubular calyx has no organizational differentiation in anatomic structure. But for G. max, its two dragonbone petals are fully united, calyx consists of epidermis and unreg ular parenchymal cells, and small degenerated vascular bundles are distributed uniformly between parenchymal ce1ls,. It is suggested that the Glycine with highly evolutionary and symmetric papilionaceous flowers still maintains the structural character of its original flowers.
