Figure 2

Example of the Eq.1 function fitted between leaf length and thermal time. Leaf elongation rate obtained by derivation of the function is shown. Are indicated: the maximum leaf length (Ym), the starting time of elongation with a leaf length of 5 mm (tc), the time when the speed elongation is maximal (tm), the time when the leaf finishes growing (te) and the leaf elongation duration (LED).
