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

缺硼使重比(LWR)提高和脉间失绿、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.

电镜观察实，NO促进玉米细胞和维管束鞘细胞中绿体的发育，绿体数量增多且体积增大，基质层和基粒数量明显增多且构完好。
