Leaf movements during waterlogging stress for different species. A, The epinastic response of the pitch movement (θp) of three potato leaves (9th, 10th, and 11th leaves) during and after 3 d of waterlogging (n = 9). B, The effect of a 3-d waterlogging treatment on three bell pepper leaves (fourth, fifth, and sixth leaves) showing an altered circadian rhythm (n = 10). C, Cucumber leaves (fourth, fifth, and sixth leaves) also show a reduced circadian rhythm after a 2-d waterlogging treatment (n = 5). D, Bean leaves (first, second, and third leaves) show a strong downward bending predominately during reoxygenation (n = 10). Shaded polygons represent the 90% confidence interval and shaded bars represent the waterlogging period.
