摘要：

The induction of alpha-amylase in aleurone cells and protoplasts of Avena fatua by a number of gibberellins (GAs) and GA-derivatives has been determined. GA1, GA4 and GA3 are of similar high activity in aleurone protoplasts, as are the more lipophilic synthetic GA4 derivatives, 2,2-dimethylGA4 and 2,2-diethylGA4. 3-epiGA4 and GA4 methyl ester have moderate activity. 3-epiGA4 methyl ester has low activity. The 2beta-hydroxylated GA8 and GA51 have very low activity in both aleurone cells and protoplasts. GA51 does not inhibit GA4-induction of alpha-amylase in aleurone protoplasts.
