  1. The results are based on the analysis of nine M. sinensis ‘Goliath’ and eight M. x giganteus plants. 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.
  2. +Statistical significance based on student t-test of M. sinensis ‘Goliath’ (n = 9) vs M. x giganteus (n = 8), **p < 0.01, ***p < 0.001, NS non-significant. Applied base temperature for thermal time calculation = 8°C, Mean of overall R2 values = 0.9932 (0.9695-0.9989).
