Abstract
The particular part of this rather broad subject to which I want to call your attention this afternoon, concerns the synthesis of vitamins in plants, and some factors which influence their production. I shall illustrate from a number of experiments, including those which we have carried out at Iowa State College on the formation of vitamins A, B1 and C. Although some vitamins, for example A and D, may be manufactured in the animal body, the ultimate source of most of the vitamins is the plant kingdom. Animals get their vitamins either directly from plants, or indirectly by varying routes, through other forms of life. It should be recalled that green plants are not by any means the only source of vitamins, but that many of the lower forms such as yeast, molds, and bacteria also produce vitamins.
