Fig. 2From: Physiological and transcriptomic comparisons shed light on the cold stress response mechanisms of Dendrobium sppAnalysis of physiological indices of HX and SH under 10℃ cold stress. (A) Peroxidase (POD) activity; (B) Malondialdehyde (MDA) content; (C) Free proline (FP) content; (D) Soluble protein (SP) content; (E) Soluble sugar (SS) content. Error bars represent standard deviation (n = 3). “*” represent a significant differences based on one–way ANOVA followed by Tukey’s multiple comparison (P < 0.05)Back to article page
