Relationship between total chlorophyll contents and (i) carotenoid (orange) or (ii) tocopherol (blue) contents in Fabaceae seeds. Each data point represents the mean value for a single species. Carotenoid and chlorophyll contents were positively correlated within the Fabaceae family due to strong correlation in the Papilionoideae subfamily. Tocopherol and chlorophyll contents were negatively correlated for the Mimosoid clade within the Caesalpinioideae. Fits a linear regression model and R² values are shown for these cases (P < 0.05).
