Somatic cells divide by mitosis producing daughter cells identical to the parent cell. 体细胞通过有丝分裂增殖产生与亲本相似的子代细胞。
Esterase analysis on leaf material from regenerants of parental and 4 putative hybrid cell lines confirmed that the 4 cell lines were all somatic nuclear hybrids. violaceus, the phenomenon of genome separation during mitosis of the hybrid cell was observed. 对其中4个分化出小植株的可能杂种细胞系进行叶片酯酶同工酶分析,证实它们均为体细胞杂种,杂种小植株在形态上兼有双亲特点且难以生根。观察到染色体组分开现象。
