| Abstract: | 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. |
