气孔器

对山东牵牛属（PharbitisChoisy）植物叶片气孔器及花粉形态特征进行了扫描电镜研究。

应用SPSS统计软件对叶表皮的特征分析后，发现种群间的气孔器密度、气孔器指数、气孔器长度、气孔器宽度、上下表皮细胞数目均随地理条件的变化而表现出明显差异。

The analysis of the epidermal characteristics by SPSS software indicated that the stomatal densities , indexes , lengths and widths , and the upper-epidermis cell numbers and the lower-epidermis cell numbers remarkably varied with geographical conditions .
