| 摘 要： | 按生物的构件理论,将冬眠苗和冬眠芽视为结缕草种群的冬眠构件,并将全体冬眠苗和冬眠芽看作潜在种群,将全体分蘖株看作现实种群,分析了4个不同生境中冬眠苗和冬眠芽的结构以及潜在种群与现实种群的数量特征。结果表明,同一生境中结缕草种群的冬眠苗和冬眠芽具有相似的结构;不同生境中,结缕草种群的冬眠构件数量、分蘖株数量差异极显著,但根状茎冬眠构件占分蘖株数量的比率没有显著差异,从而揭示了不同生境结缕草种群保持大小相对稳定及其与生境长期适应的种群动态。

| Abstract: | Zoysia japonica is a typical clonal graminaceous plant with long above ground stolons and underground rhizomes.It is widespread in the Liaodong and Jiaozhou peninsulas where it is not only a favorable pasture,but also a lawn grass with such excellent characteristics as salt-tolerance,trampletolerance,barren-tolerance,high-resistance to insects and diseases and lowexpenditure.As a perennial plant of temperate zones,Z.japonica lives through cold winters as hibernation modules called dormancy modules in terms of the modular theory of plant populations.The dormancy modules of Z.japonica populations consist of dormancy buds,consisting of stolon and rhizome buds,and dormancy seedlings,consisting of stolon seedlings and rhizome seedlings.In this paper four different habitats were selected to analyze the number and structure of dormancy modules of Z.japonica populations,the relationship between dormancy modules(potential populations) and tillers(realistic populations),and the dynamics of keeping the size of populations relatively steady and to adapt them to different habitats. |
