Legumes; Porphyrins; Root-tubercles
The root nodules of a series of legumes were investigated with and without inoculum in sterilized growing material as well as in open soil to find plants that synthesize extractable amounts of porphyrins. These experiments were a preliminary study toward the investigation of the influence of heavy metal salts on the increased production of porphyrins.
