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

缺硼使(LWR)高和片脉间失、变厚、变脆。

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促进玉米片肉细胞和维管束鞘细胞中的发育，数量增多且积增大，基质片层和基粒数量明显增多且结构完好。
