Shoot length under drought (PEG), fullerol C₆₀(OH)₂₄ nanoparticles (FNP; 0, 10, 100 and 1000 ng mL⁻¹) and combined FNP–PEG treatments (10 ng mL⁻¹ FNP+ PEG, 100 ng mL⁻¹ FNP + PEG, and 1000 ng mL⁻¹ FNP + PEG) during 72, 96, 120 and 144 h (from left–right). Shoot length is measured from period of 72 to 144 hr. Photos represent average shoot length for all treatment after 144 hr. Values are means ± S.D. (n = 3). The different letters indicate statistically significant differences among the mean values of different treatments at p < 0.05 using Tukey’s post-hoc test.
