| 摘 要： | 对国产7种和1变种兰属植物，即邱北冬蕙兰Cymbidium qiubeiense、春兰C. goeringii、春剑 C．longibracteatum、线叶春兰C．serratum、蕙兰C.faberi、送春C.fabri var．szechuanicum、寒兰C．kanran、莎 叶兰C．cyperifolium 的核型进行了研究。具体结果如下：邱北冬蕙兰为2n=40=24m+12sm+4st；蕙兰为2n=40=30m+8sm+2st；送春为2n=40=26m+l0sm+4st；寒兰为2n=40=26m+12sm+2st；莎叶兰为2n=40=24m+12sm+4st；春兰为2n=40=24m+l0sm+4st+2t;春剑为2n=40=24m+l0sm+6st。线叶春兰为2n=40=28m+l0sm+2st。线叶春兰中偶尔发现染色体数有2n=41，43，60，80。

| Abstract: | Seven species and one variety of Cymbidium are karyologically analyzed: C. qiubeiense K. M. Feng et H. Li (2n = 40 = 24m + 12sm + 4st), C. faberi Rolfe (2n = 40 = 30m + 8sm + 2st), C. faberi var. szechuanicum (Y. S. Wu et S. C. Chen) Y. S. Wu et S. C. Chen (2n = 40=26m+ 10sm + 4st), C. kanran Makino (2n = 40 = 26m + 12sm + 2st), C. cyperifoliumWall. ex Lindl. (2n = 40 = 24m + 12sm + 4st), C. goeringii ( Rchb. f. ) Rchb. f (2n = 40 =24m+ 10sm+4st+2t), C. longibracteatum (Y. S. Wu et S. C. Chen)Y. S. Wu et S. C.Chen (2n = 40 = 24m + 10sm + 6st) and C. serratum (Schltr) (2n = 40 = 28m + 10sm + 2st). In C. serratum, however, counts of 2n = 41, 43, 60, 80 are of occasional occurrence. |
