Abstract
Radioactive gibberellic acid has been used to obtain direct evidence that, during germination of barley, transport occurs along vascular strands of the scutellum towards the dorsal (non-furrowed) surface of the grain. Preferential stimulation of the dorsally-placed aleurone cells therefore accounts for the normal asymmetric pattern of enzymic modification that occurs during malting. In the scutellum, gibberellic acid is transported at a rate of about 2.5 mm per hour. It is suggested that rapid development of the vascular system in the scutellum may be an important feature of barleys that malt rapidly.Keywords
