The three treatments containing S. luteus (S. luteus ? T. virens, S. luteus 30 days ? T. virens, and S. luteus) displayed high b-1,3-glucanase and chitinase activities compared to the control (Table 6). The b-1,3-glucanase activity was *2.3-fold higher than that of the control. Seedlings inoculated with S. luteus 30 days ? T. virens displayed the highest activity compared to the other treatments. Seedlings inoculated with S. luteus ? T. virens displayed *0.9fold lower activity than seedlings inoculated with S. luteus 30 days ? T. virens, but no significant difference (P[0.05) from seedlings inoculated with S. luteus alone was observed for this treatment. The chitinase results were similar to those for b-1,3-glucanase. However, the fungalinoculated seedlings did not exhibit significantly increased activity compared to the control. The highest increase in chitinase activity was observed in the seedlings inoculated with S. luteus 30 days ? T. virens—this activity was only *1.4-fold higher than that of the control.
