摘要
本文以藓类植物的幼嫩孢蒴及茎尖为材料,对产于中国秦岭的六种提灯藓的染色体进行了观察计数。首次报道了M.pseudolycopodioides的染色体数目为n=6;M.marginatum和M.lycopoidioides的染色体数分别为n=12及n=6,与前人报道的结果一致;M.Laevinerve、M.heterophyllum以及M.thomsonii的染色体数目均为n=6,与前人的报道不完全相同。本文旨在为本属的研究提供一定的细胞学资料。
Reported in this paper are chromosome numbers of six species of Mnium from Qinling Range . The chromosome number of M. pseudolycopodioides, n=6, is reported here for the first time. The counts for M. marginatum and M. lycopoidioides, n=12 and n = 6 respectively, agree with the previous reports ?and those for M. laevinerve, M. hetero-phyllum and M. thomsonii, here all found to be n = 6, differs from some or all previously published chromosome numbers for these three species.
