Water deprivation acclimation experiment. Approximately 15-d-old plants were exposed to 14 d of water deprivation (dwd) until reaching a RWC of 49% alongside well-watered control plants. Both groups of plants were then rewatered and allowed to recover for 20 h. Plants that recovered from water deficit (acclimated) and control plants (nonacclimated) were then subjected to further water deprivation for up to 15 d post recovery (dpr). Water deficit-acclimated plants were resistant to further water deprivation and were able to maintain a higher RWC compared to nonacclimated plants. ND, Not determined.
