Figure 2.

Root development of Arabidopsis wild-type Col-0 on increasing concentrations of ACC with and without 1-MCP treatment. Arabidopsis wild-type Col-0 was sown on 0, 10, 50, 100, and 500 µM ACC with or without treatment with 250 ppm 1-MCP. (A) Pictures of representative 2-week-old plants under long-day conditions (16-h light/8-h dark) at light intensity of 70 μmol m⁻² s⁻¹ at 21°C. (B) Root length of 2-week-old Col-0 plants. Data from a representative experiment are shown; further corroborated by a minimum of three independent experiments. Different letters indicate statistically significant differences between the different groups (Kruskal-Wallis, Dunn’s Multiple Comparison Test, P < 0.01; 28 ≤ n ≤ 44). Error bars are SD. Effect sizes are presented in Table S1 .
