摘要: 对生长在不同生态环境的蝶形花科Fabaceae大豆属Glycine的两个野生大豆G.soja品系进行了扫描电镜观察及比较研究。结果表明,生长在盐渍生态环境的野生大豆茎和叶体表都具有盐腺,盐腺圆球型,基部有一个小柄,着生在盐生野生大豆茎、叶表皮外切向壁的胞间层处。幼嫩的盐腺靠泌盐孔泌盐,成熟的盐腺靠整体破碎释盐。而生长在黑土地生态环境的野生大豆的茎和叶外切向壁未发现有泌盐的盐腺,其茎叶的表皮都呈现出平滑状态。因此两种不同生态环境的同科同属植物在微观结构上显示出明显差异。

Abstract: Observations on two ecotypes of Glycine soja under scanning electronic microscope showed that the ecotype growing in saline ecological environment had salt glands on the surface of its stems and leaves, which distributed at intercellular layer,in the shape of ball and with a handle at the base. Younger salt glands secreted salt ions through their secretary pores, and mature ones did it by breaking themselves. The ecotype growing on black soil did not have any salt glands on the surface of its stems and leaves, and the surface was smooth. Therefore, the ecotypes of G.soja growing in different ecological environments displayed an obvious difference in their microstructure.
