| Research Abstract |
Symptoms of asparagus decline had common histological characteristics, which coincide with the symptoms of Fusarium root rot, so that biological factors mainly lead to the decline phenomena. Tolerance to Fusarium crown and root rot occurred by the inoculation of arbuscular mycorrhizal fungi, non-pathogenic Fusarium oxysporum, in addition, synergetic effects appeared by NaCl treatment. Antioxidative ability and free amino acids showed close association with the disease tolerance.
