Ⅰ、引言对花粉形态学的观察,很早以前就使用光学显微镜了。最近,我们可以看到很多使用扫描电子显微镜观察的资料。但是,就花粉管从花粉粒的何处产生,向哪个方向生长,用扫描电子显微镜观察的例子还没看到。由于光学显微镜的焦点深度浅,用光学显微镜

I. INTRODUCTION The observation of pollen morphology has long been done using light microscopy. Recently, we have seen many observations using scanning electron microscopy. However, it has not been observed by scanning electron microscopy that pollen tubes grow from where and from which pollen grains grow. Due to the shallow depth of focus of the optical microscope, an optical microscope was used
