丛枝菌根真菌（AMF）协会增加植物的抗逆性。本研究旨在探讨丛枝菌根真菌对盐胁迫下黄瓜生长和代谢变化的缓解作用。盐度降低了水含量和色素的合成。但接种AMF后，其生物量、色素合成、超氧化物歧化酶、过氧化氢酶、抗坏血酸过氧化物酶和谷胱甘肽还原酶等抗氧化酶活性以及抗坏血酸含量均有所提高，这可能是由于AMF降低了脂质过氧化和电解质渗漏的结果。AMF接种植物中酚类和脯氨酸的积累也介导了超氧自由基的消除。此外，茉莉酸，水杨酸和几个重要的矿物元素（K，Ca，Mg，Zn，Fe，Mn和Cu）的增强与有害离子如Na+的吸收显着减少。说明AMF对盐胁迫下黄瓜的生长具有一定的保护作用。
Arbuscular mycorrhizal fungi (AMF) association increases plant stress tolerance. This study aimed to determine the mitigation effect of AMF on the growth and metabolic changes of cucumbers under adverse impact of salt stress. Salinity reduced the water content and synthesis of pigments. However, AMF inoculation ameliorated negative effects by enhancing the biomass, synthesis of pigments, activity of antioxidant enzymes, including superoxide dismutase, catalase, ascorbate peroxidase and glutathione reductase, and the content of ascorbic acid, which might be the result of lower level lipid peroxidation and electrolyte leakage. An accumulation of phenols and proline in AMF-inoculated plants also mediated the elimination of superoxide radicals. In addition, jasmonic acid, salicylic acid and several important mineral elements (K, Ca, Mg, Zn, Fe, Mn and Cu) were enhanced with significant reductions in the uptake of deleterious ions like Na+. These results suggested that AMF can protect cucumber growth from salt stress.
