采用盆栽模拟涝渍环境的试验方法，研究了淹水胁迫对耐涝性不同的乌桕1年生实生苗的叶片质膜透性和渗透调节物质的影响。结果表明：与耐涝性强的浙江种源相比，耐涝性差的福建种源在淹水胁迫下叶片积累了更多的丙二醛，对叶片的伤害更大。浙江种源蛋白质质量分数先上升后缓慢下降，福建种源显著下降；浙江种源脯氨酸质量分数低于对照，福建种源则不同程度的高于对照水平；浙江种源可溶性糖质量分数一直保持较高的水平，且变化幅度不大，福建种源叶片可溶性糖质量分数均呈下降趋势。

The experiment was conducted to study the watelogging tolerance and adaptation mechanisms of Sapium sebiferum seedlings under watelogging conditions with one-yearseedlings of two provenances ( Zhejiang & Fujian) of Sapium sebife-rum grown in pots.Compared with Zhejiang provenance, Fujian provenance accumulates more MDA with larger damage to leaf.The content of soluble protein of Zhejiang provenance increases firstly and then decreases during the treatment, but that of Fujian provenance reduces significantly.Compared with controls, the content of free proline of Zhejiang provenance is significantly lower, while Fujian provenance is higher.The content of soluble sugar of Zhejiang provenance increases and then maintains at a higher level compared to controls, but that of Fujian provenance with a downward trend.
