G arrick , L. S., and H. M. H abermann . (Goucher Coll., Baltimore, Md.) Distribution of allagochrome in vascular plants. Amer. Jour. Bot. 49(10): 1078–1088. Illus. 1962.—Allagochrome is a blue‐green, water‐soluble pigment which can be reduced with a change in color to yellow and is autoxidizable in the presence of molecular oxygen. The development of quantitative procedures for assay has made possible an intensive study of its distribution in a wide variety of plant materials. The survey of 124 species representing 112 genera summarized in this paper indicates its presence in 55 of the species assayed. Quantitative estimates have been made of its concentrations in species showing positive tests. The widespread occurrence of allagochrome in vascular plants suggests a common function or accumulation as a metabolic product. The significance of variation in the position of absorption peaks, correlation of occurrence with known cases of cyanide‐resistant respiration, and species specificity of the chemistry of allagochrome are discussed.
