Introduction of an Improved Method for Studies of Stomatal Movement
介绍一种改进的研究气孔运动的方法

The method for measurement and record of stomatal morphological characters, distribution, and diurnal course is introduced by using scanning electron micrography after fixing leaf sample in liquid nitrogen. The example has showed that the method can successfully record stomatal diurnal course of the stomatal openness after application of the method. Especially this method is suitable for the leaf with pubescence.
