| 摘 要： | 通过对朝鲜碱茅种群正常花序大样本取样的调查与测定，定量分析了松嫩平原朝鲜碱茅种群的有性生殖构件数量特性，结果表明：朝鲜碱茅种群的有性生殖构件各组成之间具有较强的变化规律，均受到生殖蘖高、花序长、花序节数3者不同程度的制约；花序各构件在空间上的分布也存在较强的规律性。

| Abstract: | According to investigation and measurement by a large amount of random sampling in the normal spikes, some characters on sexual modules of Puccinellia chinamposis population in alkalized meadow in the Songnen Plain of China are quantitatively analyzed in this paper. The results show that there are obvious regularities among every sexual module. The regularities of the spatial distribution of spike are obvious, either. |
