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