摘　　要：为了解外源激素对高羊茅种子萌发的影响,试验以多年生冷季型草坪草高羊茅(技巧2号、盆景3000)为植物材料,用不同浓度的水杨酸(SA)、赤霉素(GA)和脱落酸(ABA)进行处理,分别研究不同浓度外源激素诱导对高羊茅种子萌发的影响。结果表明:最适合高羊茅萌发的外源激素为0.5 mmol/L SA、300 mg/L GA,可以在一定程度上促进高羊茅种子的萌发;而ABA诱导后对高羊茅的萌发有一定的抑制作用。To understand the effects of exogenous hormones on the seed germination of Festuca elata,the skills 2 and Bonsai 3000 from Festuca elata as perennial cool- season turfgrass were used for the plant materials. The seeds of Festuca elata were treated with different concentrations of ssalicylic acid（ SA）,gibberellin（ GA）,and abscisic acid（ ABA）,respectively. The effects of the induction with different concentrations of exogenous hormones on the seed germination of Festuca elata were investigated,respectively. The results showed that the most suitable exogenous hormones for the seed germination of Festuca elata were 0. 5 mmol / L SA and 300 mg / L GA,which could promote the seed germination of Festuca elata to a certain degree. However,ABA had certain inhibitory effect on the seed germination of Festuca elata after induction.
