摘　　要：通过扫描电镜观察,测量并计算气孔的纵、横径,首次采用外径长宽比与内径长宽比作为气 孔开度指标,研究了超声处理对大叶黄杨叶片下表皮气孔开度变化的影响.LSD分析表明:对照组 和超声处理组有显著性差异.The article investigates the influence of ultrasound on stoma structure of Euonymus japonicus Thunb. leaves, using scanning electron microscopy(SEM) to observe the stoma structure, using computer system to measure and calculate the vertical aperture and the horizontal aperture of stoma. It is the first time to use the aspect ratio of outer aperture and inner aperture to be the index of stomatal aperture. The analyze of LSD indicates that there is remarkable differentia between control group and ultrasound treatment group.
