Changes in chlorophyll content (a), dry weight (b) and water content (c) during leaf development according to the NMR split scale. The results of the field experiment are compared with the results from obtained under controlled conditions [7]—Sorin et al., Botanical Studies 2016, 57; acknowledgment to Springer; [8]—Sorin et al., Planta. 2015, 24; copyright Springer. As the leaves were rearranged according to the NMR split scale after sampling, in the case of the field experiment the values corresponding to the leaf ranks between 0 and −10 are the averages ± standard deviations of data collected from leaves of four plants, for leaf rank −11 the data is the average ± standard deviations of data collected from leaves of three plants. For leaf ranks between −15 and −12 and between 3 and 1 less than tree measurements were available for analysis
