Plants were grown on gravel culture with hydroponics.

Values are means ± s.e. (n = 5). Means in the same column that have the same letter are not significantly different at P < 0·05 (Tukey's test).

RGR = ULR × LWF × SLA, 1/SLA = leaf succulence (L_FW/L_A) × LDMC (L_DW/L_FW), LWC = (L_FW − L_DW)/L_FW.
