本文对不同地理种源杉木花粉的形态、微观形态、花粉壁的结构、花粉萌发、过氧化物酶同工酶及其变异进行了分析。杉木花粉有一个萌发孔;花粉外壁为颗粒状纹饰;花粉壁可分为外壁和内壁,外壁又可分为外壁外层和外壁内层。变异分析结果表明,杉木花粉的颜色、形态、萌发孔及萌发后花粉管生长长度各种源间存在差异。 In this paper, the morphology, microstructure, pollen wall structure, pollen germination, peroxidase isozymes and their variation of different geographical provenance Chinese fir pollen were analyzed. Chinese fir pollen has a germination hole; pollen outer wall is granular ornamentation; pollen wall can be divided into outer wall and inner wall, the outer wall can be divided into the outer wall and outer wall inner layer. Variation analysis showed that the color, morphology, germination pores and pollen tube growth length of Chinese fir pollen were different among different sources.
