Abstract

The effect of VAM on reducing wilt caused by Fusarium oxysporum Schlecht. f.sp. fragariae Winks et Williams (FO) infection in strawberry and the possible mechanisms involved were investigated. Two key substances involved in disease defenses, lignin and hydroxyproline-rich glycoprotein were induced and formed in the cell wall of strawberry root, and the peak content of lignin and hydroxyproline-rich glycoprotein was obtained on the 25th day (149.52mg/g) and on the 15th day (10.08 mg/g), respectively. The activity of protective enzymes SOD, POD and CAT inoculation with VAM significantly increased when compared with the control under both CK (natural growth) and inoculated with FO. The conductivity of VAM plus FO treatment was higher than the CK treatment, but significantly lower than the FO treatment.

Keywords: Fusarium wilt, Inhibitory mechanism, Mycorrhizae fungi, Strawberry, Arbuscular Mycorrhiza.
