Effect of arbuscular mycorrhizal fungi on the physiology of Festuca arundinacea under soil compaction stress

  • The effect of arbuscular mycorrhizal fungi (AMF) on the growth and physiology of Festuca arundinacea was studied under different soil compaction stresses. The results showed that under four different types of soil compaction stress, inoculation of AMF in F. arundinacea led to higher superoxide dismutase (SOD) activity, peroxidase (POD) activity, catalase (CAT) activity, and nitrate reductase (NR) activity than that of the non-inoculated treatment, whereas malondialdehyde (MDA) content and leaf relative conductivity (EC) decreased. Soluble sugar and protein content increased with the inoculation of AMF under the same soil compaction stress, whereas proline content decreased. Inoculated treatment with AMF significantly increased the stress resistance of F. arundinacea (P<0.05), and the mixed inoculated treatment was the best.
