The boron deficiency plant appears inter-venial chlorosis, thickening, crisping leaves and increased leaf weight ratio (LWR).

缺硼使叶重比(LWR)提高和叶片脉间失绿、、。

The results showed that NO could completely reverse the inter-veinal chlorosis induced by iron deficiency and increase chlorophyll content in the leaves of maize seedlings.

电镜观察结果证实，NO促进玉米叶片叶肉细胞和维细胞中叶绿体的发育，叶绿体数量增多且体积增大，基质片层和基粒数量明显增多且结构完好。
