Abstract
Benzyladenine (BA) applied to primary leaves of intact bean plants delayed the senescence of both the leaves and the entire shoot. The retardation of senescence was manifested in higher levels of chlorophyll, protein, RNA and ribonuclease activity at all stages of development. Also, the levels of incorporation of labelled precursors into protein and RNA were enhanced. The effect of BA was largely independent of light intensity and the compound did not act merely as a nitrogen source.Keywords
