Abstract

Smoke exposure is known to influence germination of a wide variety of species. However, the influence of smoke on germination of grasses is poorly studied. In order to investigate the influence of smoke on plants native to North America, we tested five species for germination response to smoke exposure. Species tested were: sideoats grama (Bouteloua curtipendula), blue grama (Bouteloua gracilis), big bluestem (Andropogon gerardii), buffalo grass (Bouteloua dactyloides), American basket flower (Centaurea americana), and different varieties of big sagebrush (Artemisia tridentate). Seeds were treated with one of four dilutions of smoke-water and distilled water: 0:1 (no smoke), 1:10 (high smoke), 1:100 (medium smoke), and 1:1000 (low smoke). Seeds were soaked in the smoke treatment for 20 hours, then placed in a germination chamber. Multiple germination chambers will be needed because some of the seeds required different growing conditions to mimic their time of germination. We monitored the seeds daily for germination and logged growth for each. We hope to find that germination is inhibited in some species and promoted in others at different levels of smoke exposure. We perceive this happening because of past test performed on similar species to the ones that we are studying. It is our hope that we exhibit that different levels of smoke exposure could have a significant effect on germination of many plant species in North America.
