Effects of drought stress on the different physiological attributes of date palm cultivars, including (A) relative water content (RWC), (B) photosynthetic rate (Pn), (C) stomatal conductance (gs), (D) transpiration rate (E), (E) intercellular CO2 concentraion (Ci), and (F) water use efficiency (WUE). Data represents measurements taken after 90 days of drought induction. Statistical differences (pāā¤ā0.05) are indicated by different letters above the bars in the bar graph. Y-bars on each bar (where larger that than the data point) represent the the standard deviation within replicate.
