摘　　要：以6个勋章菊品种(系)"星白""红纹"‘红吻’"鸽子舞""黄火焰"和"白火焰"的盆栽苗为试材,采用人工干旱胁迫(不浇水)处理,研究了基质中水分极限含量(萎蔫系数)对勋章菊抗旱性的影响。结果表明:‘红吻’"鸽子舞"和"白火焰"的萎蔫系数分别为11.44%、11.89%和9.89%;"星白"和"黄火焰"的萎蔫系数分别为8.89%和7.78%;而"红纹"的萎蔫系数最小,仅有7.44%。该结果为勋章菊在苏州地区的引种和景观应用提供参考依据。Six cultivars of potted seedlings of Gazania rigens（L.）were used for artificial drought stress（without irritation）experiment.These cultivars were‘Xingbai＇‘Hongwen＇‘Red kiss＇ ‘Gazoo red withring＇‘White flame＇and‘Yellow flame＇.The effect of limit moisture content in substrate（wilt coefficient）on Gazania rigens（L.）drought tolerance was studied.The results showed that the wilt coefficient of‘Red kiss＇ ‘Gazoo red withring＇and‘White flame＇were 11.44%,11.89% and 9.89% respectively;the wilt coefficient of‘Xingbai＇and ‘Yellow flame＇the wilt coefficient were 8.89%and 7.78%respectively;the wilt coefficient of‘Red strip＇was 7.44%,which was the lowest one among the six accessions of Gazania rigens（L.）.These results provided scientifically bases for Gazania rigens（L.）introduction and landscape application in Suzhou area.
