Fig. 3From: Unsupervised analysis of NIRS spectra to assess complex plant traits: leaf senescence as a use caseTime course of chlorophyll content (A) nitrogen content (B) and water content (C) of an individual flag leaf from flowering to maturity. The dash-dot lines represent the experimental date issued from NIRS calibration while the full lines result from the logistic curve modelled for each leaf trait. The red and black dots correspond to the T0 and T1 of each kineticBack to article page
