Advances in research on smoke-promoted seed germination
摘要
Abstract
Fire is an important driver of plant regeneration in global terrestrial ecosystems.Post-fire seed germina-tion is a critical adaptive feature of plants in fire-prone environments.Smoke produced by pyrolysis of plant materi-als in wildfire contains various active chemical compounds,which can activate soil seed bank via initiating post-fire seed germination.Karrikins produced by cellulose pyrolysis are usually considered as the primary smoke cue that promotes seed germination.Recently,it has been found that lignin-promoted syringaldehyde can also trigger seed germination of post-fire plants.Here,we review the history of research on smoke cues and their ecological relevance to post-fire plant regeneration,and discuss the evolutionary aspects of smoke adaptation of plants.On basis of these discussions,we propose some important scientific questions about smoke-promoted seed germination to get some perspective on future research.关键词
