Arabidopsis thaliana seedling growth conditions, workflow schematic and biometric analysis. (A) Medium conditions used to induce stress: S1—salt stress, low concentration; S2—salt stress, high concentration; H1—hydric stress, low concentration; H2—hydric stress, high concentration; Ox—oxidative stress; Zn—metal stress induced by zinc. (B) Schematic representation of the analysis performed. (C) Arabidopsis thaliana seedlings size comparison in stress conditions. (D) Bar plot of the average measured root size in stress conditions relative to control. * Indicates statistically experimental values (p < 0.05) while ** indicates statistically experimental values (p < 0.1). Scale bars: (C) 0.1 cm.
