Relative water content (RWC, %) in response to dehydration stress in leaves of trained or non-trained maize plants. RWC was measured in leaves harvested after air drying for the indicated times (in min, shown on the ‘x’-axis), for plants experiencing their first stress (dark blue line) or for trained plants exposed to three stress cycles (pink line). Points are the mean, and error bars are ± SE from three independent experiments, each performed with 8–10 leaves from three separate plants.
