Dry Matter Contribution by Cotyledons of Lima Beans and Other Epigeal Legumes¹

Lima beans (Phaseolus lunatus L.) were compared with four other species of epigeal legumes for the effectiveness of their cotyledons in carbon assimilation. Measurements of growth of seedling organs following shading of the cotyledons permitted the species to be divided into three groups: 1) species in which the cotyledons have negligible photosynthetic activity — lima beans, mung beans (P. aureus Roxb.), and kidney beans (P. vulgaris L.); 2) a species in which the cotyledons have a slight significance as photosynthetic organs — soybean (Glycine max (L.) Merrill); and 3) a species in which the cotyledons are important as photosynthetic organs — subclover (Trifolium subterraneum L.)

Key Words: Seedling growth • Photosynthesis • Reserve depletion • Kidney bean • Soybean • Mung bean • Subterranean clover
