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。

Abstract: 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 Guanxi sweet pomelo.
