砧板柚花粉发育过程外壁糖蛋白形成的透射电镜分析

采用细胞化学技术，经钉红对砧板袖几个不同发育阶段的花粉进行染色显示，用透射电镜对花粉外壁糖蛋白进行了细胞化学定位观察，探讨了花粉发育过程中外壁糖蛋白的发生时期及输送到花粉壁的过程。研究结果表明，花粉外壁糖蛋白在单核花粉时期由绒毡层细胞产生，并被分泌到药室内，输送到花粉外壁及萌发孔周围积累和贮存，整个过程延续到花粉成熟．

The electron microscopy analysis on the development of exine glycoproteins during the growth of Zhen Ban Yu pollen

By means of cytochemisty, Ruthenium red has been applied to show the staining display of pollen of Zhen Ban Yu (a variety of Citrus grandis) in its different growing phases and electron microscopy has been used to observe the cytochemisty localotion of glycoproteins of pollen .The text tried to make a study of glycoproteins in the producing and transmitting phase .The study showed that the pollen surface glycoteins is produced by tapetum cell in mononuclear pollen phase and secreted to endothecium and then transmitted to exine surface of pollen for accumulation and store .The whole process continues till the pollen is mature.
