| Notes | [Objective]The present study was carried out to assess the changes of defense-related enzyme activi- ties in sugarcane under ratoon stunting disease （RSD）, in order to provide references for illustrating the mechanism of interaction between sugarcane and the bacteria of RSD. [Method]Sugarcane variety of GTll was selected as the plant materials. Seedcanes were treated at 52 ℃ for 30 min for pathogen free as a control and inoculated with Leifsonia xyli subsp. Xyli（Lxx）as RSD-infected sugarcane. The healthy and RSD-infected sugarcane was confirmed by PCR and the change of defense-related enzyme activity in sugarcane was analyzed in both treatments. [Result]The activities of CAT, SOD, POD and GR in stem were lower in RSD-infected treatment than those in control on the 90th day after transplant, while they were higher in treatment on the 180th day after transplant as comparison with the control except the activity of APX which was higher in treatment than this in control during sugarcane growth period.
