| 摘 要： | 应用灰色关联分析方法研究了坪用草地早熟禾地上生物量、生殖枝数、生殖枝高、穗长、穗粒数、结实率等6个主要经济性状与种子产量以及各性状之间的关联程度。结果表明，各性状与种子产量之间的关联度大小依次为单位面积生殖枝数＞单位面积地上生物量＞生殖技高＞穗长＞结实率＞穗粒数。地上生物量对生殖校高、生殖枝数和穗长的影响较大。

| Abstract: | The relation between seed yield and other characters for Poa pratensis was studied by Grey Relational Analysis method. The results showed that order of relational degrees between seed yield and other characters was the quantities of reproductive stems. m-2>aboveground biomass.m-2> the height of repreductive stems > ear length > rate of seed setting > seed quantities of per ear.The alers ground biomass has larger influence on the height and number of reproductive stems and ear length for ho pratensis. |
