Fig. 5From: Predicting the quality of ryegrass using hyperspectral imaginga Differences in the mean HSI spectra (SNV) between leaves (blue) and pseudostems (red). b Grouped scatter plot of the first two canonical variables obtained from a one-way multivariate analysis of variance of the PS + BL mean HSI spectra (n = 200). The first canonical variable provides a clear separation between ryegrass genotypes with blades (black crosses) and pseudostem (red circles)Back to article page
