CERTAIN plants exhibit marked differences in leaf dimorphism and other characters at different stages of growth from the early seedling to the adult plant capable of flowering and fruiting. Few investigations have been made on the chemical differences which accompany these changes. Hess1, working with English ivy, Hedera helix Linn., found larger amounts of certain growth promoting or root forming materials, as identified by the mung bean test, in the juvenile shoots than in adult flowering and fruiting stems. He has been able to identify several of these substances as phenolic compounds.
