Fig. 10From: Estimation of area- and mass-based leaf nitrogen contents of wheat and rice crops from water-removed spectra using continuous wavelet analysisRelationships of LMA with (a, b) wavelet features and (c, d) ND indices derived from MR spectra (left column) and WR spectra (right column). Red, blue and black lines represent linear fits on RICE, WHEAT and pooled data, respectively. All regressions are statistically significant (p < 0.001)Back to article page
