摘　　要：以生长一致的10叶龄"星白"勋章菊扦插苗为试材,研究涝渍胁迫对"星白"勋章菊生长及其叶片生理的影响。结果表明:随着胁迫时间的延长,细胞膜透性增大,相对电导率增加,叶绿素含量是先增大后逐渐减小;苗木总生物量呈下降趋势。结合水培试验,"星白"勋章菊具有较强的耐涝渍能力,是一种适宜在城市园林中广为应用的优秀园林绿化植物。Using 10 leaPage ＇Xingbai＇ C, azania cutting seedlings with the same growth as test material, the effect of waterlogging sress on the growth and physiological of ＇Xingbai ＇ Gazania were studied. The results showed that with the extension of stess time, cell membrane permeability became strong, relative electric conductivity incresed as well, chlorophyll content increasing first and then decreasing, while total biomass tended reduced. Combinating hydroponic experiment, and concluded that ＇Xingbai ＇ C-azania had stronng waterlogging-resistant ablity,it was an excellent landscape plant which was suitable in city garden.
