Figure 7. Effects of AMF and AC treatments on the competition of S. canadensis (experiment 3).

Figure 7

Competitive ability (as indicated by the aggressivity index) of S. canadensis as affected by AMF (AMF or No AMF) and activated carbon (AC or No AC) (experiment 3). A lower value for the index indicates greater competitive ability. Values are means ± SE. Means for No AC with different uppercase letters and means for AC with different lowercase letters are significantly different at P<0.05. For comparison of paired bars (No AC vs. AC), asterisks indicate significant differences (*<0.05), and ns indicates not significant.
