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

缺硼使叶重比(LWR)提高叶片脉间失绿、厚、脆。

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促进了玉米叶片叶肉细胞维管束鞘细胞中叶绿体的发育，叶绿体增多且体积增大，基质片层基粒显增多且结构完好。
