Study on the Pollen Morphology of Masson Pine and Other Pine Species and Varieties

HE Yu-you; QIN Guo-feng; GAO Ai-xin; WANG Zhou-lian

Observations through scanning electron microscope showed that the pollen of 9 p ine species and 3 varietiesincluding masson p ine were consist of a main body and two air-sacs. The air-sac was the basic morphologicalcharacteristic of these pollen. The air-sac had net-like texture and the exine of proximal face of pollen had uniquesculp tural texture. The pollen of different species and varietieswere different in sizes: the longestwas 54. 3μm and41. 5μm as the shortest in average. As to individual pollen grains, the longestwas 67μm and the shortest 35μm.The size and sculp tural texture was stable, which could be used to identify the pollen of different species.
