摘　　要：以黄山贡菊、亳菊、野路菊(WY4)、萨摩野菊(BG1)、阴歧油菊(GD6)为研究对象,采用盆栽方式,通过观察5种菊属(Chrysanthemum)植物在干旱胁迫下的形态特征变化,测定与抗旱性相关的指标如株高、根冠比、叶片相对含水量(RWC)和叶绿素含量,对5种菊属植物的抗旱性能进行了探讨。结果表明,5种菊属植物的抗旱性从强到弱依次为萨摩野菊(BG1)>野路菊(WY4)>黄山贡菊>亳菊>阴歧油菊(GD6),其中萨摩野菊(BG1)的抗旱性最强,可作为药菊优异抗旱种质加以利用。By taking Chrysanthemum morifolium(Ramat.)Tzvel. ‘Gongju',C.morifolium‘Bozhou',C.crassum(BG1),C.japonense(WY4),C.okiense(BG1)as the research object,with the method of potted plant,by studying the five species of genus Chrysanthemum,chlorophyll under drought stress change and the determination of the related drought resistance indexes such as plant height,root-shoot ratio,leaf relative water content(RWC)and chlorophyll content,the drought resistance of five species of Chrysanthemum was discussed,and the results showed that 5 species of Chrysanthemum the drought resistance of plants from strong to weak was C.crassum(BG1) > C.japonense(WY4) >C.morifolium(Ramat.)Tzvel.Gongju, >C.morifolium‘Bozhou' >C.okiens(BG1).C.crassum(BG1)had the strongest drought resistance,which could be used as an excellent drought-resistant germplasm.
