Control chamber: Regular watering (80% FC) and optimum temperature (30°/23 °C day/night temperature); DT chamber: withhold watering at 45 days after transplanting the ramets and kept at optimum temperature (30°/23 °C day/night temperature); DT + HT chamber: imposed HT after 72 h of DT (35°/25 °C day/night temperature); Leaf tissue samples were collected at 0 h-DT (dt), 72 h-dt/0 h-HT (ht), 96 h-dt/24 h-ht, 120 h-dt, 48 h-ht, and 144 h-dt/72 h-ht impositions
