Comparative Effects of 6‐Furfurylaminopurine and 6‐( γ, γ‐ Dimethylallylamino) purine on Growth, Peroxidase, Chlorophyll and Carotenoid Content. — 6‐Furfurylaminopurine (FAP) and 6‐(γ, γ‐dimethylallylamino) purine (IPA) both inhibit root growth and cause an increase in peroxidase activity. When used at 10 −8 and 10 −8 M , IPA stimulates elongation of the coleoptile test, at 10 −4 M both FAP and IPA provoke an inhibition. FAP and IPA maintain a high level in chlorophylls and carotenoids in floating leaves discs. In all these experiments, IPA has thus a higher effect than FAP.
