摘要 首次报道了瑞丽茜树的染色体数目和核型。结果表明:瑞丽茜树的染色体为二倍体,染色体较小,长度在1.25~2.25μm,核型公式为2n=2x=22=10m+2sm,属于"2A"型。 The chromosome number and karyotype of Fosbergia shweliensis(Anth.) Tirveng. Sastre are reported firstly.The results show that the chromosome of Fosbergia shweliensis is diploid and small,its length ranges from 1.25 μm to 2.25 μm,the karyogram fits well to the formula of 2n=2x=22=10m+2sm,and the karyotypc belongs to the type of "2A".
