The fire ephemeral Tersonia cyathiflora (Gyrostemonaceae) germinates in response to smoke but not the butenolide 3-methyl-2H-furo[2,3-c]pyran-2-one

Abstract

Although many smoke-responsive seeds germinate in the presence of KAR(1), this does not apply universally. This suggests that other chemical(s) in smoke-water may play an important role in stimulating the germination of certain species.
