THE SHAPE OF BAMBOO POLLENS AND THEIR GERMINATION TEST

13 species of bamboo pollen which belong to 4 genera were measured,the range of diameter is between 35.0-79.8μm.The diameters of the 6 species of bamboo pollen which belong to Phyllostachys are over 50 μm; these spores are of large size.Most of the bamboo pollen of Pleioblastus,Pseudosasa and Indosasa are of middle size spores with the diameters between 25-50 μmn.It was showed by electron microscope scanning that the shape of bamboo pollens is subsphaeroidal,each of the bamboo pollens has an approximate round germinal aperture with ring,the veins of the spore wall are granular or wart like,there are little differences between species.The germination percentage of the bamboo pollens in 5% sugar solution are 53.4% the most,2% the least.Sugar solution is the suitable culture solution.
