【摘要】 分别以小立碗藓(Physcomitrella patens)和水稻(日本晴亚种)(Oryza sativa spp.japonica)为标样,用流式细胞术分别测定了中华蓑藓(Macromirium cavaleriei)、钝叶蓑藓(M.japonicum)和缺齿蓑藓(M.gymnostomum)3种藓类植物的DNA C-值,由此建立了应用流式细胞术测定蓑藓属植物DNA C-值的方法,讨论了影响藓类植物DNA C-值测定结果的因素.最后讨论了苔藓植物DNA C-值变异式样、系统发育和分类学意义,以及今后有关藓类植物DNA C-值研究中值得关注的几个方向.更多还原

【Abstract】 The DNA C-values of three Macromitrium species(including M.cavaleriei,M.japonicum and M.gymnostomum) were determined by flow cytometry by using Physcomitrella patens and Oryza sativa spp. japonica as standard samples,respectively.Thus the method of measuring DNA C-values of Macromitrium species by flow cytometry was established.The factors influencing the measuring result were also discussed.Finnally,variaiton patterns of bryophytes DNA C-values,their phylogenetic and taxonomic significances,and some interesting topics about DNA C-value research were remarked.更多还原
