摘要: 利用透射电镜,对缺铁黄瓜幼叶肉细胞的超微结构及植株的某些形态学进行了观测,发现缺铁后的幼叶细胞内首先受到影响的细胞器是叶绿体,其次是线粒体,细胞核、内质网结构完好。幼苗缺铁20天后, 大部分叶绿体的基粒片层和间质片层受到了严重的破坏。少量线粒体出现空泡化倾向,植株在形态学上表现为幼苗长势衰弱,叶色发黄、叶绿素含量下降。

Abstract: We had observed the ultrastructure of cells of cucumber young leaves lacking iron with transmission electron microscopy and had determined changes of some morphology of plant. First the choloroplast structure was broken, and second some mitochondria structure was damaged. The structure of nucleus and endoplasmic reticulum kept intact. After lacking rion for twenty days, most thylakoid of the chloroplast of the young seedlings disintergrated, some cavities appeared in the mitochondrin. Plants were weak. Leaves turned yellow. The contents of chlorophyll were lower.
