Is the positive response of seed germination to plant-derived smoke associated with plant traits?

摘要: Abstract Relationships between seed germination response to plant-derived smoke and various plant traits (habitat requirements, life form, morphology, bank type) were analysed for 97 species of the Hungarian flora using published data. It was hypothesized that smoke-responsive – those displaying enhanced in differ from non-responsive having an indifferent or inhibitory effect on habitat requirements and/or certain history traits. To our knowledge, no such comparison has previously been reported a European flora. We found indicating disturbance preferring soils rich moderately nitrogen more frequent group (80% 41%, respectively) than group, while contained high percentage natural (i.e. dominant characteristic communities; 47%) indicative nutrient poor (38%) (sub)mesotrophic soils. Annuals biennials (67%) dominated whereas these short-lived perennial herbs equally abundant (43% each). There tendency higher frequency long-term persistent among (78%) (54%). These findings suggest smoke-stimulated is associated with only few specific semiarid temperate region Europe, but highlight occurrence smoke-enhanced short-lived, nitrophilous tolerant species. results can contribute better understanding post-fire regeneration communities, could also be considered during vegetation restoration weed management.
