非潮汐淹水对白骨壤膜脂过氧化系统的影响

摘要

Avicennia marina （Forsk.） Vierh, was submerged to different levels of non -tidal waterlogging to study the permanent influence of inundation condition on membrane lipid peroxidation system, aiming to evaluate its tolerance to non - tidal waterlogging. The results indicated that SOD（ superoxide dismutase） of A. marina treated with seven inundation gradients had stable sequence within the two experimental stages, while CAT （eatalase） and MDA （malondialdehyde） also showed the same profile. This paper aims to provide reference for water level control in the non - tidal waterlogging conditions, which was specified as one of the key technologies performed during mangrove afforestation at non - tidal habitats.%通过室内模拟非潮汐淹水，探索不同淹水水位条件下，红树植物白骨壤（A．marina（Forsk．）Vierh）．超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、丙二醛（MDA）随时间的变化情况。结果表明，经历第二个淹水周期后，较第一个周期各梯度，白骨壤超氧化物歧化酶活性（SOD）从高到低排序不变，过氧化氢酶活性（CAT）、丙二醛的量（MDA）也表现出相同的规律。本研究结论为红树植物在人工非潮汐生境下，红树林造林的关键技术之一——淹水水位的控制提供了数据参考。
