In every agricultural system, weed seeds can be found in every cubic centimeter of soil. Weed seeds, as a valuable trait underlying the fate of weed populations, exhibit differing levels of seed dormancy, ensuring their survival under uncertain conditions. Seed dormancy is considered as an innate mechanism that constrains germination under suitable conditions that would otherwise stimulate germination of nondormant seeds. This work provides new insight into changes in germination patterns along the dormant to nondormancy continuum in seeds with physiological dormancy. Notable findings are: (1) germination synchrony can act as a new parameter that quantitatively describes dormancy patterns and, subsequently, weed population dynamics, (2) germination synchrony is dynamic, suggesting that the more dormancy decreases, the more synchrony is obtainable, (3) after-ripening and stratification can function as a synchronizing agent that regulates germination behavior. Freshly harvested seeds of Brassica napus with type 3 of non-deep physiological dormancy showed the most synchronous germination, with a value of 3.14, while a lower level of germination asynchrony was found for newly harvested seeds of Sinapis arvensis with type 1 of non-deep physiological dormancy, with an asynchrony value of 2.25. After-ripening and stratification can act as a synchronizing factor through decreasing the asynchrony level and increasing synchrony. There is a firm relationship between seed dormancy cycling and germination synchrony patterns, ensuring their survival and reproductive strategies. By germinating in synchrony, which is accompanied by cycling mechanisms, weeds have more opportunities to persist. The synchrony model used in the present study predicts germination behavior and synchrony along the dormant to nondormancy continuum in weed seeds with physiological dormancy, suggesting a useful method for the quantification of germination strategies and weed population dynamics.

The relationship between seed mass and germination traits remains unresolved, with conflicting theoretical predictions. Some studies suggest larger seeds exhibit superior germination and post‐germination performance, while others indicate the opposite, possibly due to environmental factors and additional seed traits. To clarify this relationship, we conducted a phylogenetically informed meta‐analysis of 1889 plant species worldwide. Our findings show that seed dormancy is strongly associated with seed mass, but the direction and magnitude of this relationship vary by dormancy type, with lower seed mass in physiologically dormant seeds (−0.026) and higher seed mass in morphophysiologically (0.066) and physically dormant seeds (0.598). Trade‐offs and correlated evolution have influenced seed mass, which exhibits notable phylogenetic conservation. Contrary to predictions, larger seeds did not consistently germinate faster or to a higher percentage (−0.648 and 0.890), likely due to interactions with growth form, dormancy class, and phylogenetic history. These findings highlight the importance of considering seed traits, growth form, and evolutionary relationships when examining plant adaptation and germination strategies.

During stressful climatic periods, plant populations face significant challenges, especially during germination and seedling establishment. Theoretical studies present conflicting findings regarding the relationship between seed size and germination rate. Some analyses suggest that species with larger seeds should exhibit rapid germination, while others point to faster germination in smaller seeds. This discrepancy can, for example, be attributed to the higher vulnerability of larger seeds to post-dispersal seed predation. To assess the correlation between seed mass and seed germination characteristics at a global scale, we performed a rigorous meta-analysis of published data sources, covering a wide range of germination traits across 1877 species with diverse dormancy types and global distribution. Additionally, we investigated the potential relationship between seed mass and dormancy level. Our findings revealed contrasting responses of germination traits to seed mass, suggesting complex eco-evolutionary correlations among these traits. Trade-offs and corelated evolution likely played an important role in the evolutionary history of seed mass, with seed mass displaying notable trait conservation across the phylogeny. Interestingly, our study demonstrated that seed dormancy exhibited trade-offs with post-germination traits and seed mass. The meta-analysis demonstrated that any changes in the relationship between seed mass and dormancy is dependent on dormancy types with physiological dormancy showing lower seed mass while other dormancy types were has a higher seed mass. These results underscore the critical role of seed mass in shaping plant performance and provide valuable insights into plant trait evolution. Our findings clearly indicate that the hypothesis of larger seeds conferring advantages in both pre- and post-germination traits might not be empirically true in all cases as theoretical studies suggest and that this relationship is complex and varies among species and growth forms. We interpret these results within the context of germination strategies and correlated evolution between seed dormancy and seed mass. Considering these traits in future analyses of plant germination strategies and species distributions is crucial. Factors such as lifespan, seed mass, and germination-related traits should be carefully considered to gain a comprehensive understanding of plant adaptation to challenging environmental conditions.

Seed plants dominate terrestrial ecosystems in part because regeneration is not a single event, but a coordinated sequence of traits acting across time and space. Here, we synthesize regeneration strategies in seed plants as a continuous, integrated framework spanning pre‐germination regulation, germination timing, seedling emergence, soil seed banking, seed production, and dispersal. Drawing on examples from deserts, forests, fire‐prone shrublands, wetlands, and alpine systems worldwide, we show how these stages are evolutionarily coupled into coherent regeneration syndromes that maximize fitness under distinct environmental regimes. Dormancy, serotiny, germination cue sensitivity, and bet‐hedging strategies regulate the timing of recruitment; seed size, reserve allocation, and emergence traits mediate early survival; soil seed banks and mast seeding buffer populations against temporal variability; and dispersal mechanisms determine spatial escape, colonization, and coexistence. Rather than acting independently, these traits interact to resolve fundamental trade‐offs between risk avoidance and opportunity capture, producing predictable patterns across life histories, biomes, and phylogenetic lineages. Viewing regeneration as a continuum clarifies why contrasting strategies, such as rapid germination versus prolonged dormancy, prolific seed output versus large‐seed investment, or local retention versus long‐distance dispersal, can each be adaptive depending on ecological context. We argue that this integrative perspective provides a unifying framework for understanding plant persistence, community assembly, and evolutionary diversification, and is essential for predicting seed regeneration outcomes under accelerating climate change and altered disturbance regimes.
