锌缺乏或过量使小麦叶肉细胞变小,多环复式细胞显著减少。缺锌植株的叶绿体中基粒垛数少,基粒垛叠片层少,基质片层少,部分片层膨胀;叶绿体内包含较大的液泡和淀粉“泡”;叶绿体被膜模糊,甚至消失.锌过量则使小麦的叶绿体变小,基粒和基质片层明显减少,部分片层膨胀,亲锇颗粒多;在叶绿体周围线粒体出现较多. Lack of zinc or excess of wheat mesophyll cells smaller, polycyclic multiple cells significantly reduced. The chloroplast of zinc-deficient plants had fewer basal pallets, fewer basal pallets and fewer stroma lamellae, and some of the laminae were swollen. Chloroplasts contained larger vacuoles and starch “bubbles”; the chloroplasts were fuzzy and even disappeared. Zinc excess will make wheat chloroplast smaller, base and matrix lamellae significantly reduced, some lamellar expansion, pro osmium particles more; around the chloroplast mitochondria appear more.
