Asterisks denote significant differences according to Mann-Whitney U test between water-stressed (WS) and well-watered (WW) plants at the same time point. **, and *** indicate significantly different values at p < 0.01, and p < 0.001. T1: starting point where both WW and WS plants were maintained under well-watered conditions; T2-T4: WS plants were maintained at 50% of FC (moderate deficit); T5-T7: WS plants were maintained at 30% of FC (severe deficit); T8-T9: recovery period, WS plants were rehydrated at 90% of FC
