【摘要】 该文介绍了安徽苦草(Vallisneria anhuiensis)和长梗苦草(V.longipedunculata)的生物学特性,观察了它们的繁殖方法,分析了它们的生殖价。苦草有营养生殖和有性生殖2种繁殖方式。通过观察和实验,我们了解了苦草的生态对策。通过生态对策苦草将达到最佳利用资源环境。这对于苦草的进一步生长和发育是非常重要的。苦草雄蕊的花药和花药壁的退化消失,是对水面上及时传粉的适应。更多还原

【Abstract】 The biological traits of Vallisneria anhuiensis and V. longpedunculata have been introduced in this paper.Their productive method has been observed,and reproductive value has been analyzed.Vallisneria possess two patterns of asexual reproduction and sexual production.By observing and experiment,we have understood a bionomic strategy of Vallisneria.Vallisneria will attain an optimization in habitat utilization by the bionomic strategy.It is very important for Vallisneria to grow and develop further.The stamen of Vallisneria is shorts of anther or a wall of anther,which adapts to the pollination on surface of water in time.更多还原
