摘要
对北京松山国家级自然保护区11种苔藓植物的染色体进行了观察和计数,结果为:(1)片叶苔属之一种(RiccardiaSP。)n=10,(2)无纹紫背苔(PlagiochasmaintermediumLindenb.etGott.)n=7+m;(3)地钱(MarchantiapolymorphaL.)n=9,(4)蛇苔(Conecephalumconicum(L.)Dum.)n=9,(5)韩氏真藓(Bryumof.handeliiBoth.)n=10;(6)Rryumof.cernum(Hedw,)Lindenb.)n=10;(7)多褶青藓(Brachytheciumbuchananii(Hook.)Jaeg.n=10,(8)青藓(BrachytheciumrivulaveB.S.G.)n=10,(9)钝叶匍灯藓(Plagiomniumrostratum(Schrad.)T.Kop.)n=6;(10)粗枝藓属之一种(Gollaniasp.)n=10;(11)牛角藓(Cratoneuronfilicinum(Hedw.)Spruc.)n=9。
