Fitted curves of the relationship between transpiration rate (E) and leaf relative water content (RWC) for Col-0 (red and blue lines) and Cvi-0 (purple and green lines) Arabidopsis accessions of leaves of plants that had been exposed for 4 d to moderate (red and purple symbols) or to low (blue and green symbols) VPD. The leaves were first saturated in degassed deionized water and after 1h measurements were conducted during desiccation at VPD of 1.40 kPa. The R square of goodness of fits was 0.9±0.1.
