摘　　要：对国产 7种和 1变种兰属植物 ,即邱北冬蕙兰Cymbidiumqiubeiense、春兰C .goeringii、春剑C .longibracteatum、线叶春兰C .serratum、蕙兰C .faberi、送春C .faberivar.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 =2 4m + 1 2sm + 4st;蕙兰为 2n=40 =30m + 8sm + 2st;送春为 2n=40 =2 6m + 1 0sm + 4st;寒兰为 2n =40 =2 6m + 1 2sm + 2st;莎叶兰为 2n =40 =2 4m + 1 2sm + 4st;春兰为 2n =40 =2 4m + 1 0sm + 4st+ 2t;春剑为 2n =40 =2 4m + 1 0sm + 6st。线叶春兰为 2n =40 =2 8m + 1 0sm + 2st。线叶春兰中偶尔发现染色体数有 2n =41 ,43,60 ,80。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. cyperifolium Wall. 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.
