| 摘 要： | 为明确薇甘菊萎蔫病毒(Mikania micrantha wilt virus,MMWV)对薇甘菊(Mikania micrantha)叶片生理生化的影响,探讨了MMWV侵染对薇甘菊叶片超氧化物岐化酶(superoxide dismutase,SOD)、过氧化物酶(peroxidase,POD)、多酚氧化酶(polyphenol oxidase,PPO)和苯丙氨酸解氨酶(phenylalanine ammonia-lyase,PAL)活性及叶绿素总含量和光合特性的影响.结果表明:MMWV感染薇甘菊16d内叶片的SOD活性均比对照组高,其中第16天达最大值,但接种后第24和32天SOD活性分别比对照低了13.28％和25.37％；POD活性在接种后16-32d均显著高于对照.PPO和PAL变化趋势相似,在接种后第8天这两个酶的活性分别比对照高了77.75％和23.58％,而在第32天分别比对照减少了14.27％和20.53％.随着侵染时间的增加,感病薇甘菊叶片中叶绿素含量减少,叶绿素a/b值逐步降低；同时最大净光合速率(Pmax)和光饱和点(LSP)分别比健康对照减少了32.34％和12.52％,而对暗呼吸速率(Rd),光补偿点(LCP)和表观量子效率(AQY)无显著影响.表明MMWV侵染可减低薇甘菊叶片光合作用的效率.
