Fig. 2 A matrix scatter plot of total chlorophyll concentration (Chl_t; µg cm^-2), the fluorescence measures F_o/F_v and F_o/F_{5 min}, and the reflectance measures R₇₅₀/R₅₅₀, R₇₅₀/R₆₅₀ (wavelengths in nm), yellowness index (YI), and normalized difference vegetation index (NDVI) showing qualitative relationships among all of the spectral measures and Chl_t. Data are from measurements on the index leaf from each harvest from all experiments
