| 摘 要： | 采用多因素正交试验设计,通过大样本相关、通径和逐步回归分析后表明,高羊茅5个种子产量因子对种子产量的直接贡献大小排序为:生植枝数/m2＞小花数/小穗＞种子粒数/小穗＞单粒种子重＞小穗数/生植枝;提高小花数/小穗和种子粒数/小穗可最有效提高高羊茅的种子产量,其次是提高生植枝数/m2. |

| Abstract: | Based on multi-factor orthogonal designed field experiment, to the seed yield, the order of Festuca arundinacea L. seed yield components effects is linked in the following sequence: shoots/m~2> florets/spiklet>seed numbers/spiklet>seed weight>spiklets/shoot; Increasing seed numbers/spiklet and florets/spiklet are the most productive on the seed yield, the next is the shoots/m~2 after path coefficient analysis. |
| Keywords: | Festuca arundinacea L Seed yield Seed yield components Path coefficient analysis |
