Abstract— A relationship between Chl a and each of its accessory pigments, neoxanthin, violaxanthin, lutein, Chl b and carotene, is demonstrated in soybean and peanut genotypes. These genotypes include normal and Chl-deficient types. Plots of Chl a content against accessory pigment content generate straight-line relationships that are extrapolated to intersect the Chl a axis. The points of intersection correctly predict the order of origin of certain accessory pigments (lutein, carotene and Chl b ), but incorrectly predict that neoxanthin and violaxanthin arise after the introduction of Chl a . |
