摘要
报道了四川省都江堰市龙池地区5种苔藓植物配子体的染色体研究结果，5种材料均取其生长点或茎尖，观察和计数了细胞有丝分裂中期的染色体数。1．中华扁萼苔（RadullachinensisSteph．var．rotundistipa）n=8；2.蛇苔（Conocephalumconicum（L．）Dum．）n=9；3．长齿匍灯藓（Plagiomniamdrummondii（Bruch．＆Schimp．）Kop．）n=6；4．新船叶藓（NeodolichomitragiganteaNog．）n=5;5．东亚小金发藓（Pogonatuminflexum（Lindb．）Lac．）n=7．其中中毕扁萼苔和新船叶藓的染色体数为首次报道．
The chromosome numbers of mitosis metaphase of stem apex or growing point of 6 bryophytes species in Sichuan Dujiangyan Longchi area are reported. 1. Radulla chinensis Steph. var. rotundistipa n=8; 2. Conocephalum conicum (L.) Dum. n=9; 3. Plagiomnium drummondii (Brachy. & Schimp.) Kop. n= 6; 4.Neodolichomitra gigantea Nog. n=5; 5. Pogonatum infexum (Lindb.) Lac. n=7. The chromosome numbers of Radulla chinensis var. rotunditipa and Neodolichomitra gigantea are reported for the first time.
