摘　　要：利用细胞学及系统进化方法,分析了禺毛茛复合体及其近缘种的多倍体现象,以及多倍体对植物物种形成、形态、生态及生理等方面的影响。结果表明:禺毛茛复合体及其近缘种的多倍体现象突出,多倍体在形态上更为粗壮、生态分布上范围更大、生理上由于基因组的相容性水平提高而使得植株的适应性及抗逆性增强。The polyploid in complex of Ranunculus cantoniensis and its allied species as well as the influence which polyploidy affected on speciation , morphology , ecology and physiology were analyzed by cytologic and phylogeny evolution method.The result showed that polyploid in complex of R.cantoniensis and its allied species were common. Polyploid was thicker and strong in morphology , distributed range was wider in ecology and its adaptability or stress resistance was bigger because of higher compatibility of genomic.
