Abstract
Cytokinin levels in both attached and detached mature leaves of poplar (Populus x robusta) increase transiently after short periods of exposure to red light. The degree and rapidity of response seems dependent on the physiological condition of the leaves. The cytokinin, 6-(2-hydroxybenzyl)amino purine riboside, specifically increases after red light treatment. Diurnal changes of leaf cytokinins occur, with a pronounced peak of activity being present at daybreak.Keywords
