Abstract

IT is well known that kinetin, the most important cytokinin, exerts its action by stimulating nucleic acid and protein synthesis in plants1–4. N6-benzyladenine, another potent cytokinin, exhibits some physiological effects in common with that of kinetin, that is, promotion of leaf growth5,6, inhibition of leaf senescence and preservation of chlorophyll7,8. It is not, however, known as yet whether or not nucleic acid and protein metabolism is also influenced by this cytokinin. We have investigated the incorporation of precursors into nucleic acid and protein fractions and determined the concentrations of these constituents in bean leaves after treatment with benzyladenine.
