| 摘 要： | 多花野牡丹(Melastomaaffine)为两性花、异型雄蕊类型,为探究异型雄蕊生物学功能差异对幼苗适合度的影响,本试验采用动态生命表方法,研究7种授粉方式对多花野牡丹结实及幼苗的动态生命过程.结果表明:种子的出苗率与千粒重无密切关系.自然授粉萌发率(92.5%)和出苗率(88.0%)最高,紫红色花药授粉在萌发率、出...

| Abstract: | Melastoma affine is bisexual flower and heteranthery.To explore the effect of differentiation of biological function on seedlings fitness,this paper discusses the dynamic life course of seeds and seedlings of seven kinds of pollination way of M.affine with dynamic life table method.The result showed that the emergence percentage had no close relation with 1 000-grain weight.Natural pollination yielded the highest germination rate(92.5%) and the emergence percentage(88.0%).The germination rate,emergence perc... |
