摘　　要：笃斯越桔是大兴安岭地区的重要经济树种。为给其遗传育种和引种栽培提供参考依据,应用扫描电子显微镜,对大兴安岭16个地区的笃斯越桔花粉形态进行了观察,并根据花粉的大小、萌发沟长、花粉壁纹饰等性状指标对不同地区的花粉进行了聚类分析。观测结果表明:大兴安岭16个地区的笃斯越桔花粉在其部分形态特征上保持了一致性,均为四合花粉、六条萌发沟、近球形等;同时,在花粉部分形态特征上也表现出了特异性,如花粉大小、萌发沟长、极面观及花粉壁纹饰等;其花粉直径在24.12~39.12μm之间,萌发沟长在13.86~26.76μm之间,极面观为圆形和三角形,花粉壁纹饰主要有疣状纹饰、颗粒状纹饰、波纹状纹饰等。分析结果表明:大兴安岭地区的笃斯越桔具有丰富的遗传多样性。The Vaccinium uliginosum is an important economic tree species in Daxing＇anling. In order to provide basis for genetic breeding and introduce cultivation, scanning electron microscopy was used to observe the pollen morphology of Vaccinium uliginosum in 16 different areas of Daxing＇anling, and the pollen of different areas was cluster analyzed according to the pollen size, germination ditch length, pollen wall decoration and so on. The Result showed that the pollen morphology of 16 areas in Daxing＇anling were consistent in some pollen morphological characteristics, such as tetragonal pollen, six germination ditch, near spherical shape and so on. Pollen morphology, such as pollen size, germination ditch length, polar view and pollen wall ornamentation, also showed the specificity in some of the pollen morphological characteristics. Pollen diameter between 24.12-39.12 μm; germination ditch between 13.86-26.76 μm; polar view of the round and triangular; the pollen wall decoration mainly warty ornamentation, granular ornamentation, corrugated decoration, etc. The results of the analysis showed that the Vaccinium uliginosum in Daxing＇anling areas has rich genetic diversity.
