Fig. 4From: High-throughput analysis of leaf physiological and chemical traits with VIS–NIR–SWIR spectroscopy: a case study with a maize diversity panelLab-measured versus VIS–NIR–SWIR predicted maize leaf properties for the 40% test set. The orange squares are plants from Field− N; blue squares are plants from Field + N; black squares are plants from greenhouse. The black dashed line is 1:1 line. Statistics for the predictions can be found in Table 1Back to article page
