摘　　要：对哈密瓜细菌性果斑病(Acidovoraxavenaesubsp.citrulli)不同抗性的哈密瓜品种的气孔形态及绒毛形态进行了扫描电镜观察,从所测得数据看出:抗病品种的气孔在形态、大小上与感病品种无明显差异,但抗病品种叶片单位面积内的气孔数量明显多于感病品种;另外,抗病品种的绒毛在形态上与感病品种无差异,但抗病品种的绒毛比感病品种的长并且单位面积上的数量比感病品种明显多。这些现象为抗病品种优势的表现提供了一定的形态学依据。Abstract ： The characteristics of leaf stomata and pile of different Hamimelon ecotypes were studied by scan electron microscope. The results indicated： The stomata shape and size between the resisting disease type （Kangbinghongcuibao） and the infecting disease type （Xinmiza No. 7 8601 ） were insignificant , but the stomata density of Kangbinghongeuibao is higher than very much. Besides, the leaf pile shape of Kangbinghongcuibao and Xinmizal No. 7 8601 was similar, but the leaf piles of Kangbinghongcuibao were longer than Xinmizal No. 7 8601, and the quantity of pile was more than Xinmizai No. 7 8601 obviously. These phenomenon provided important morphology foundation for the superiorities of the resisting disease types.
