摘要：

以3个考来木品种为研究对象,调查了其在人工模拟根系全部淹没、半淹两种不同程度水涝胁迫下,其质膜透性、叶绿素含量、可溶性蛋白含量、SOD活性、游离脯氨酸含量等生理指标的变化,发现各个指标之间具有一定的关联性。其中一个品种抗全淹能力相对较弱,叶片失水严重;而在半淹状态下,3个品种在整个处理过程中无明显变化,可见半淹不能对考来木造成危害。初步筛选出2个优良耐水湿考来木品种。

摘要：

Three cultivars of Correa seedlings were selected to investigate their endurance of flooding stress.physiological indicators, including consist of membrane permeability, chlorophyll, the soluble protein, SOD activities and proline were measured under half and full root-submersion conditions,there has a certain correlation between different indexes.One of the varieties is relatively weak ability to resist full root-submersion condition and the leaves with serious water loss; in the whole process has no obvious changes when the three varieties are under half root-submersion conditions, and half root-submersion conditions cannot cause a visible harm.Results showed Correa ‘Dusky Bells' and Correa alba had higher tolerance to waterlogging.
