| 摘 要： | 探讨了6种观赏草种子萌发期耐盐性。通过用不同浓度氯化钠溶液处理6种观赏草种子,记录发芽情况,采用隶属函数法对6种观赏草种子萌发时期的耐盐性进行综合评价。结果显示,在不同氯化钠盐溶液胁迫下,6种观赏草种子的相对发芽率、胚根相对长度、简易活力指数随着盐浓度的升高而明显下降,综合评价得出6种观赏草种子的耐盐性由强到弱的顺序为:芨芨草(Achnatherum splendens)>丽色画眉草(Eragrostis spectabilis)>小兔子狼尾草(Pennisetum alopecuroides cv.‘Little Bunny’)>花叶芒(Miscanthus sinensis'Varie gatus')>野古草(Arundinella hirta)>拂子茅(Calamagrostis epigeios)。本研究结果可以为盐碱地区绿化选择观赏草种植提供理论依据。

| Abstract: | The salt tolerance of 6 ornamental grass seeds during germination was studied,with different concentrations of sodium chloride solution.The performance of germination was recorded.Comprehensive evaluation of salt tolerance of 6 ornamental grass seeds was carried out by membership function method.Under different salt concentration stress,the relative germination rate,radicle length and simple vigor index of each ornamental grass seed significantly decreased with the increase of salt concentration,respecitively.According to the comprehensive evaluation,the order of salt tolerance of 6 ornamental grass seeds was listed as below:Achnatherum splendens>Eragrostis spectabilis>Pennisetum alopecuroides cv.‘Little Bunny’>Miscanthus sinensis'Variegatus'>Arundinella hirta>Calamagrostis epigeios.The results of this study can provide a theoretical basis for the selection of ornamental grass planting in saline alkali areas. |
