A researcher observes that a batch of dormant seeds fails to germinate even after scarification and exposure to favorable conditions. Suspecting the presence of a volatile inhibitor, which experimental setup is MOST appropriate to confirm this hypothesis?
Grind the dormant seeds and apply the extract to non-dormant seeds.
Place the dormant seeds in a closed container with non-dormant seeds of a different species and observe germination rates.
Expose the dormant seeds to high concentrations of ethylene gas.
Soak the dormant seeds in a solution of gibberellic acid.
