通过盆栽试验，研究了丛枝菌根真菌（AMF）对田菁（Sesbania sesban）的胁迫效应。对所选的S.测量了sesban。盐度降低生长和叶绿素含量急剧而AMF接种植物提高生长。由于盐胁迫导致固氮和同化潜力降低，根瘤数量、根瘤重量和固氮酶活性也明显下降。接种AMF可提高这些指标，并在一定程度上缓解盐胁迫。抗氧化酶如超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、抗坏血酸过氧化物酶（APX）和谷胱甘肽还原酶（GR）以及非酶抗氧化剂（抗坏血酸和谷胱甘肽）也表现出很大的变化。盐度引起内源生长激素水平的变化与脱落酸表现出增量。接种AMF的植株保持较高的生长激素水平，也减轻了盐的负面影响。
Pot experiments were conducted to evaluate the damaging effects of salinity on Sesbania sesban plants in the presence and absence of arbuscular mycorrhizal fungi (AMF). The selected morphological, physiological and biochemical parameters of S. sesban were measured. Salinity reduced growth and chlorophyll content drastically while as AMF inoculated plants improved growth. A decrease in the number of nodules, nodule weight and nitrogenase activity was also evident due to salinity stress causing reduction in nitrogen fixation and assimilation potential. AMF inoculation increased these parameters and also ameliorated the salinity stress to some extent. Antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) as well as non enzymatic antioxidants (ascorbic acid and glutathione) also exhibited great variation with salinity treatment. Salinity caused great alterations in the endogenous levels of growth hormones with abscisic acid showing increment. AMF inoculated plants maintained higher levels of growth hormones and also allayed the negative impact of salinity.
