  1. Bd3-1 (n = 7), Bd21 (n = 10) plants, Bd21-3 (n = 7) plants, Bd2-3 (n = 10). Lm: final leaf length; LERmax: maximal leaf elongation rate; t20%, t50%, t90%, te: time points at which the leaf reaches 20%, 50%, 90% and 100% of the final leaf length, respectively; tm: time point at which the leaf reaches LERmax; LEDs: leaf elongation durations between above stated thermal time points.
