Action comparée de la 6-furfurylaminopurine et de la 6-(γ, γ-dimethylallylainino)purine sur la croissance, l'activité peroxydasique, la teneur en chlorophylles et en caroténoïdes

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^?8M, IPA stimulates elongation of the coleoptile test, at 10^?4M 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.
