Abstract: The chromosome numbers and karyotypes of three Zelkova Species from China are reported for the first time . The results are as follows: Z. schneideriana Hand .-Mazz ., 2n = 2x = 28 = 14m + 14sm; Z. serrata (Thunb .) Makino, 2n= 2x = 28 = 26m+ 2sm; Z. sinica Schneid , 2n = 2x = 28 = 20m+ 8sm .

Key words:

Zelkova

摘要： 报道了我国3 种榉属(Zelkova) 植物核型。结果如下: 大叶榉(Z. schneideriana Hand .-Mazz .) 2n = 2x = 28 = 14m+ 14sm; 光叶榉(Z. serrata (Thunb .) Makino) 的核型公式为2n= 2x = 28 = 26m + 2sm, 1、2、3 对染色体的短臂上有次缢痕存在; 大果榉( Z. sinica Schneid) 的核型公式为2n = 2x = 28 = 20m + 8sm。
