Root growth in response to several stressors. LEH of untreated roots and roots treated during 3 hours with 5μM ACC, 10μM zeatin, 200μM mannitol, 200μM glucitol or 50μM CuSO₄ (means ± SD, in triplicates). Values after all treatments are statistically significant versus the untreated Col-0 (t-test, p<0.05, n>10).
