木贼科气孔器的扫描电镜观察

The scanning electron microscope observation of the stomatal apparatus of Equisetaceae

首次用扫描电镜比较观察了木贼科不同生境的问荆(Equisetum arvenseL.)、草问荆(E.pratenseEhrhart)、林问荆(E.sylvaticumL.)、水问荆(E.fluviatileL.)、木贼(Hippochaete hyemaleL.)等5种植物地上茎气孔器的详细特征,提供了直观的立体图象,并从比较形态学的角度,初步讨论了木贼类的系统学和生态学意义。

This paper show the detailed characters of stomatal apparatus of supra terraneous stem by comparing and observing five species of Equisetaceae from the different habitats under SEM for the first time. They are Equisetum arvense , E. pratense , E. sylvaticum , E. fluviatile , provides intuitive and three-dimensional pictures and tentatively discusses the Equisetaceae＇ s significance of systematics and ecology from the perspective of comparative morphology.
