Three-dimensional (3D) scatter plot showing relationships between spectral ratios, and key growth parameters in basil cultivar “Emily”. Each subplot represents one measured trait (Z-axis) in relation to spectral values. The X-axis (blue numbers) corresponds to the deep red to blue (DR:B) ratio, and the Y-axis (red numbers) to the deep red to far-red (DR:FR) ratio. The color gradient indicates the magnitude of each trait value (visualizations generated using the scatter3D function from the plot3D package in R).
