摘　　要：以盆栽常绿欧洲荚蒾幼苗为试验材料,研究了幼苗在浸水处理条件下的相关生理指标。结果表明:在水涝胁迫下,常绿欧洲荚蒾叶片中脯氨酸含量、可溶性蛋白含量和可溶性糖含量显著高于对照,表明常绿欧洲荚蒾通过积累这些物质来适应水涝逆境。到水涝胁迫处理12 d,尽管叶片的叶绿素含量有所下降,相对电导率增至24.8%,但与对照相比,植株外表的生长状况并无多大变化,说明常绿欧洲荚蒾较耐水涝。This paper mainly studied on relevant physiological indexes of Viburnum opulus var.under flooding stress by carrying out a water soaking treatment for the potted seedlings.The results showed that Viburnum opulus var.adapted flooding stress by accumulating the proline content,the soluble protein content and the soluble sugar content under flooding stress.After 12 days flooding stress,the chlorophyll in leaves of Viburnum opulus var.was decreased,the conductivity percentage was 24.8%,but the change of growth status was slight,all of these indicated that Viburnum opulus var.had a strong waterlogging tolerance ability.
