Gibberellin from Barley Embryos


IN recent years, considerable interest has been shown in the potentialities of the aleurone layer of barley as a site for synthesis of α-amylase in response to added gibberellins1,2. It now seems probable3 that, when barley germinates without additives, an endogenous gibberellin is concerned in the formation of many of the hydrolytic enzymes which degrade the reserves of the endosperm. It was therefore of interest to study the embryo with a view to determining which tissues may be involved in the production of the postulated enzyme-inducing hormone.
