Abstract
Dormant, intact Avena fatua L. (wild oat) seeds germinate poorly at 20 °C. Removing the hulls slightly increased germination. Treatment with smoke solutions increased the germination of both intact seeds and caryopses. Exogenous GA3, alone or in the presence of smoke solution, increased the germination of caryopses, while ACC shows a tendency to increase germination of caryopses only when applied in combination with smoke solution. Results suggest that GA3 and ethylene, but not smoke solutions, are involved in the regulation of α-amylase activity during germination. However, the participation of smoke solutions in the control of ACC oxidase activity cannot be excluded.
