Abstract
The rapid increase in acidic gibberellin-like (GA-like) activity occurring in etiolated wheat (Triticum aestivum L.); leaf tissue in response to red light is phytochrome controlled. The production of some of the GA-like activity appears to possess a similar escapetime from far-red reversibility to leaf unrolling and is sensitive to Amo 1618. Application of these GA-like substances to leaf sections maintained in the dark causes unrolling. Increased GA-like activity can also be detected in non-irradiated portions of partly irradiated leaves.Keywords
