研究了不同浓度NaCl对大豆（Glycine max [ L.]梅尔湾Pershing）接种或不接种丛枝菌根真菌Glomus etunicatum Becker & Gerdemann。此外，盐驯化的菌根真菌对抗氧化酶在盐胁迫（100 mM NaCl）下生长的大豆植株的影响进行了研究。NaCl胁迫下，菌根和非菌根植株地上部超氧化物歧化酶（SOD）、过氧化物酶（POD）和过氧化氢酶（CAT）活性均升高。盐胁迫提高了M和NM植株根系SOD活性，但对CAT和多酚氧化酶活性没有影响。盐胁迫下，M植株的SOD、POD和抗坏血酸过氧化物酶活性较高。在盐胁迫下，接种盐预处理的菌根真菌的大豆植株地上部SOD和POD活性比未接种的提高。
The effects of different concentrations of NaCl on the activities of antioxidative enzymes in the shoots and roots of soybean ( Glycine max [ L.] Merr cv. Pershing) inoculated or not with an arbuscular mycorrhizal fungus, Glomus etunicatum Becker & Gerdemann, were studied. Furthermore, the effect of salt acclimated mycorrhizal fungi on the antioxidative enzymes in soybean plants grown under salt stress ( 100 mM NaCl) was investigated. Activities of superoxide dismutase (SOD), peroxidase (POD), and catalase ( CAT) were increased in the shoots of both mycorrhizal (M) and nonmycorrhizal (NM) plants grown under NaCl salinity. Salinity increased SOD activity in the roots of M and NM plants, but had no effect on CAT and polyphenol oxidase activities in the roots. M plants had greater SOD, POD and ascorbate peroxidase activity under salinity. Under salt stress, soybean plants inoculated with salt pre-treated mycorrhizal fungi showed increased SOD and POD activity in shoots, relative to those inoculated with the non pre-treated fungi.
