WebAt the end of this time, the embryos and ambient solutions were separately extracted. Gibberellin-like activity in the extracts was determined with the barley endosperm bioassay using seed from the same variety, harvest and treatment schedule as was employed for the embryo diffusion experiments. WebGibberellic acid (GA3) and other gibberellins enhance the release of reducing substances from barley endosperm (PAL~G, 1960; Yo~o, 1960). The quantity of reducing substances released is proportional to the logarithm of gibberellin concentration applied (PAL~G et al., 1964; NIC~OLLS and P ~ n G , 1964).
