On the relative role of the scutellum and aleurone in the production of hydrolases during germination of barley

Abstract

The relative roles of the scutellum and the aleurone layer in the production and mediation of both germination-specific α-amylase and cell wall breakdown hydrolases has been examined in vivo following treatment of barley seeds with the plant hormones gibberellic acid and abscisic acid. To facilitate entry of these exogenous hormones, a technique is presented where multiple incisions (>nicks
