Variations in stress indicators [including the relative water content (RWC), photosystem II maximum quantum yield efficiency (Fv/Fm), chlorophyll a/b ratio, and total chlorophyll content] in Pepton-treated tomato plants compared to controls under well-watered or water-stressed conditions. Data are the means ± SE of n = 10 individuals. Results of statistics (two-way ANOVA with Tukey HSD post hoc test) are shown in the inlets. Arrows represent days of watering and Pepton application.
