Resumen:
Smoke water is well known for its role in seed germination. Many pyrolysis by-products from industry may provide the same ecological function as smoke water, including stimulation of seed germination. Germination responses were assessed for 17 grass species (native to western Canada and commonly used in land reclamation)and 6 pyrolysis by-product solutions (karrikinolide, smoke water, coke, bottom ash, fly ash, biochar) in a laboratory experiment. For 10 of the 17 species studied, germination percentage was significantly increased by at least one pyrolysis by-product, and 3 species were stimulated by all pyrolysis by-products; 3 species had germination reduced by pyrolysis by-products; and almost a quarter of the species were unaffected by pyrolysis byproducts.
