摘　　要：草地早熟禾（ＰｏａｐｒａｔｅｎｓｉｓＬ．）是建植北方冷季型草坪的首选草种之一。针对其在草坪建植中存在的发芽率低、萌发速度慢等问题，对草地早熟禾的两个品种（“纳苏”和“菲尔金”）进行了种子预措引发试验研究。探讨了水分调控、温度调节、激素处理、电场处理等方法对种子发芽的影响。结果表明，虽然两品种对不同处理的反应有一定的差异，但所用各种处理均对种子的发芽有一定的影响。Kentucky bluegrass (Poa pratesis L.) is one of the most important cool-season turfgrass in north China. Poor germination performance (Low germination rate and speed) limited the widespread use of this species. To improve its germination, several pre-sowing seed treatments, including hydration-dehydration, temperature adjustment, hormone regulating, electricity treatment, were used. The results showed that most of the pre-sowing treatments have positive effects on the germination of Kentuky bluegrass seeds, in terms of increasing its germination rate and germination speed.
