Effect of LMA on spectral variation between 2200 and 2350 nm (leaf panel) and 1500–1650 nm (right panel). a, c Represent the MR spectra and the corresponding wavelet power spectra at scale 4. b, d Represent the WR spectra and the corresponding wavelet power at scale 4. The location and width of the Gaussian-shaped wavelets for the best LMA-sensitive wavelet features WF2273,3 and WF1578,4 from MR and WR spectra are presented in (a) and (b), respectively. The black arrows in (c) and (d) point to the wavelength locations of WF2273,3 and WF1578,4, respectively
