Abstract Background and Aims Fire-released seed dormancy (SD) is a key trait for successful germination plant persistence in many fire-prone ecosystems. Many local studies have shown that fire-released SD depends on heat exposure time, dose of smoke-derived compounds, class, lineage the fire regime. However, global quantitative analysis lacking. We hypothesized more prevalent than non-fire-prone ecosystems, crown-fire compared to surface-fire Additionally, uncovering patterns relationship between cues classes at scale mirror those identified or regional was expected. Methods Totally, 246 published during 1970-2022, encompassing 1782 species from 128 families used our meta-analysis. Meta-analysis moderators included different cues, smoke application methods, duration concentration, fire-proneness, regimes, ecosystem types. Key Results Heat released physical, physiological morphophysiological dormancies.
