| 摘 要： | 采用改良刮制法研究了典型粳稻，典型籼稻，偏籼型，偏粳型和陆稻等10个水稻品种的气孔性状，研究结果发现，剑叶的气孔密度在水稻类型间和品种间具有明显差异。是一个品种特性，光照强度减弱使各品种上三叶的气孔密度明显减少。其原因是由于叶面积增大，气孔行数减少和每一行中相邻气孔间距离增大共同作用的结果。品种不同，其气孔密度对光强变化的反应亦不同，光照强度减弱对剑叶气孔大小有显影响。

| Abstract: | This study consists of 10 varieties which belong to typical japonica, typical indica ,indica-clinous ,japonica-clinous and upland rice.The density and size of stomata were measured with the desiliconization and scraping into shape method.The results showed that stomatal density of flag leaves has significant difference among types and varieties, which is a character of variety. Stomatal density of flag leaves,2nd leaves and 3rd leaves decreased positively under low light, which result from the increase of leaf area, stomatal band and stomatal distance between same stomatal band. Stomatal density of different varieties showed different change under low light. Low light has significant influence on stomatal length and width of flag leaves. |
