Correlation between the stem growth (relative stem increment, RSI) and the initial assimilation rate (initial A). A was recorded the day preceding the beginning of waterlogging. The relative stem increment is the ratio of the growth during waterlogging (corresponding to the second growth flush) and the initial height of the plant (corresponding to the first growth flush), and is expressed as percentage day⁻¹. The linear regression including all of the seedlings (control and waterlogged): p = 0.0005, R²= 0.31
