A survey of anthocyanin pigments in seedling legumes

Abstract
Light-grown seedlings of 88 species of legumes were examined for anthocyanins. No red pigmentation developed in 22 species. In nearly all the 66 pigmented species, the red color was subepidermally located. Pigment determination of 40 species showed cyanidin glycosides to be the most common. In five of seven species of Phaseolus and the closely related Glycine max, however, malvidin glucoside was predominant. In four of five species of Vicia as well as in two species of Phaseolus, delphinidin glycosides were the major pigments.
