(A) The effect of indole-3-acetic acid (IAA) on the in vivo ACO enzyme activity during seedling growth of sugar beet at 20°C in darkness. (B) Effect of 1-aminocyclopropane-1-carboxylic acid (10 μM ACC, gray solid line; 1,000 μM ACC, gray dotted line) on the indole-3-acetic acid profile (IAA) during seedling growth of sugar beet at 20°C in darkness. Mean values ± SD are presented (n = 5). The asterisk indicates that the IAA treatment differs significantly from the corresponding controls (p < 0.05).
