金边万年青的核型分析和细胞学观察

Karyotype Analysis and Cytological Observation in Rohdea japonica(var. marginata)

按Levan等(1964)标准,对万年青进行核型分析发现,核型公式为2n=34=1M+9m+5sm+1st+1 t,为2B型(Stebbin,1971)。同时,对万年青有丝分裂各时期的特征进行了研究。

Karyotype of Rohdea japonica was formulated as 2n = 34 = 1M ＋ 9m ＋ 5sm ＋ 1 st ＋ 1 t, belonging to Stebbing （1971） 2B type. The characteristics of mitosis in different phases were studied in Rohdea japonica.
