Abstract
The influence of light, particularly blue and red light, on the cytokinin content of seedlings ofAmaranthus caudatus was studied. Cytokinin content was determined by two different bio-assays (amaranthin accumulation byAmaranthus seedlings and mtrate-reductase activity ofAgrostemma embryos). In both bio-assays similar results were obtained. Oytokinin content is increased, especially by blue light. It is suggested that especially blue light promotes amaranthin accumulation inAmaranthus seedlingsvia the increase of cytokinin content of tissues. The results support our hypothesis on cytokinin action.Keywords
