An effective system to produce smoke solutions from dried plant tissue for seed germination studies.

Premise Of The Study: An efficient and inexpensive system was developed to produce smoke solutions from plant material to research the influence of water-soluble compounds from smoke on seed germination. •

Methods And Results: Smoke solutions (300 mL per batch) were produced by burning small quantities (100-200 g) of dried plant material from a range of species in a bee smoker attached by a heater hose to a side-arm flask. The flask was attached to a vacuum water aspirator, to pull the smoke through the water.
