摘　　要：红肉蜜柚系芽变新株系,为探讨其变异来源,对红肉蜜柚、琯溪蜜柚、下河蜜柚的花粉进行观察比较,结果表明:红肉蜜柚与琯溪蜜柚花粉粒外壁纹饰相似,形状大小相近,与下河蜜柚差异较大;红肉蜜柚与琯溪蜜柚花粉粒同属于以5孔沟为主类型,穿孔密度差异不显著,与下河蜜柚差异较大;进一步从孢粉学上证实红肉蜜柚与琯溪蜜柚遗传距离相近。Red-flesh sweet pomelo is a new mutant strain. To study the sources of the variation, pollens of red-flesh sweet pomelo, Guanxi sweet pomelo and Xiahe sweet pomelo were compared. The results showed that： （a） the pollen external appearance, shape and size of the red- flesh pomelo were similar to those of Guanxi sweet pomelos; （b） there were greater differences between the red-flesh and Xiahe sweet pomelo; （c） the main aperture types of the red-flesh and Guanxi sweet pomelo were both 5 colporate and no significant difference in their perforation density, while apparent difference existed between the red - flesh and Xiahe sweet pomelo; and （d） sporopollen identification further confirmed that there was only a minute genetic distance between the red - flesh and Ouanxi sweet pomelo.
