摘要
首次报道了胶东半岛昆嵛山细形山地涡虫Phagocata vivida的形态特征,运用组织再生的方法获得中期分裂相分析了体细胞染色体组型,其2倍体细胞具有36条染色体,核型公式为:2n=2x=10m+26sm,并与产于日本的细形山地涡虫核型进行了比较,发现二者染色体数目相同,但核型参数存在一定差别。
The morphological character of Phagocata vivida from Mt.Kunyu over Shandong-Peninsula was reported for the first time.The karyotype of somatic cell from regeneration tissue of this planarian was also analyzed.The results indicated：the chromosome number of the diploid somatic cells is 36 with a chromosome formula of 2n=2x=10m＋26sm.Comparing the karyotype with same species distributed over Japan,both have a uniform chromosome number but with a different chromosome type.
