Treatment layout at the Darney experimental site (a) and the Compiègne beech experimental site (b) overlapped with the map of the axis 1 coordinates of the PCA for the infrared reflectance spectral data. The crossed areas correspond to additional plots, which were not retained in the definitive experimental design
