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。
In order to explore the source of variation, red meat pomelo was treated with different buds. The pollen of red meat pomelo, pomelo pomelo and lower pomelo pomelo were observed and compared. The results showed that the red meat pomelo and pomelo pomelo pollen Similar to the outer wall ornamentation, the shape of the similar size, and the next big difference between the river pomelo; red meat pomelo and pomelo peony pomelo pollen belong to the same type of 5-hole ditch, perforated density difference was not significant, The difference is greater; further confirmed from the palynology red meat pomelo and Guanxi pomelo genetic distance is similar.
