FIGURE 6.

Growth parameters in competition-grown plants. Leaf area (cm²) and dry weight (mg) of the rosettes of competition-grown plants 3 weeks after treatment with a mock, SA, MeJA, or SA/MeJA solution. Mock vs. SA and Mock vs. MeJA competition experiments were performed in one experimental round, and Mock vs. SA/MeJA, SA vs. SA/MeJA and MeJA vs. SA/MeJA competition experiments were performed in another experimental round. Asterisks indicate a statistically significant difference between the two treatments of the indicated competition tray (Students t-test; ^∗∗P < 0.01; ^∗P < 0.05). Error bars represent SE, n = 20–25 plants.
