Changes of TA in leaves of C. rochussenii (Cr), C. mayeriana (Cm), B. membranaceum (Bm), B. vaginatum (Bv), D. leonis (Dl) and P. cornu-cervi (Pc) after 1, 7 and 21 week(s) of well-watered condition under WWML (a), WWLL (b), and after 1 and 7 weeks of drought and after 14 weeks of re-watering under moderate light (c) and low light (d). Vertical error bars represent standard error. Different letters above bars indicate statistical difference (Tukey’s multiple comparison, p < 0.05, n = 3)
