| 摘 要： | 选择冷季型草坪品种高羊茅和黑麦草为材料,采用九种不同浓度的盐胁迫,应用灰色关联度方法分析牧草种子的发芽率、相对发芽率、发芽势等多项指标.结果表明：高羊茅多项指标与盐胁迫的关联度较大,说明盐胁迫对高羊茅的影响略高于黑麦草,黑麦草更适于在盐碱土上进行引种和绿化.

| Abstract: | Tall rescue and perennial ryegrass of cool season type were selected under the salt stress on nine different concentration conditions. Several indexes such as germination percentage, relative ger- mination percentage, and germination energy for pasture seed were analyzed on the gray relational grades. Experimental results revealed that the conections between various indexes of tall rescue and salt stress were closer, indicating that the effects of salt stress on tall rescue were slightly greater than perennial ryegrass which proves to be more suitable to be introduced and greened in saline soil. |
