【摘要】 运用扫描电子显微镜对4个草莓品种花粉进行观测研究,结果表明:（1）草莓花粉大小约为20.4～39.4μm×11.2～20.4μm,极面观为三裂片圆形,赤道面观为长圆形,属于中等大小花粉,在系统分类上属于N₃P₃C₃类型;（2）花粉表面纹饰为条纹纹饰,条纹走向与极轴平行,综合孢粉学分类指标,以‘章姬’的性状最为原始,其次为‘丰香’、‘春香’,‘红颜’的花粉性状最为细致;（3）发现‘红颜’的花粉中存在大量的异形花粉,异形花粉表现为发育不全,干燥后中空;（4）‘春香’花粉的条脊有不规则龟裂。更多还原

【Abstract】 The scanning electron microscopy（SEM） was used to scan the pollen of four strawberry varieties and the results showed that:（1） the sizes of strawberry pollen were about 20.4～39.4μm×11.2～20.4μm,and they were three-lobed in polar view,long round in equatorial view which belonged to medium-sized pollen and classified to N₃P₃C₃ type;（2） the ornamentation of pollen surface was striped patterns,and stripes were parallel to the axis.According to the comprehensive classification palynology indicators,‘Akihime’ had the most original characters, followed by‘Toyonoka’,‘Harunoka’,‘Benihoppe’;（3） there were a lot of abnormal pollen in‘Benihoppe’ which were not fully grown and hollow after dried; （4）‘Harunoka’ pollen had irregular cracks.更多还原
