Leaf area expansion (a) and dry matter accumulation (b), petiole and internode length (c) and diameter increasing (d) following thermal time accumulation in Apr-May 2015 and Nov-Dec 2015. Measured data of leaf expansion and petiole and internode diameter increasing were fitted by logistic curves, while measured data of leaf dry matter accumulation and petiole and internode length increasing were fitted by Boltzmann curves.
