摘　　要：分析了取自不同地区、不同性别的高山红景天叶片气孔特性。结果表明,不同地区高山红景天叶片气孔的大小、开度和密度等特性有一定的差异,且其影响因素较复杂,总的趋势是取自高海拔地区的高山红景天气孔较大而密度小,取自低海拔地区的高山红景天气孔较小而密度大。Analyzed stomatal characteristics of the different gender Rhodiola sachalinensis A. Bor grown in various regions. The results showed that there are some differences in stomatal sizes, apertures and densi- ty characteristics of the leaves of Rhodiola sachalinensis A. Bor in different areas and the influencing fac- tors was complex. And the general trend is that the stomatal size of Rhodiola sachalinensis A. Bor from the high-altitude region is bigger, while stomatal density is smaller than that taken from low-altitude re- gion.
