Correlation plots of weekly Fv/Fm ratios and their corresponding PPFD of C. rochussenii (a, g), C. mayeriana (b, h), B. membranaceum (c, i), B. vaginatum (d, j), D. leonis (e, k), and P. cornu-cervi (f, l) under drought treatment versus well-watered conditions. Pearson correlation coefficient (r value) is shown for each species. Vertical bars represent standard error. Different letters above bars indicate statistical difference (Tukey’s multiple comparison, p < 0.05, n = 10)
