Data from: Seed germination strategies reveal naturalization potential: Global insights from European herbaceous species
This dataset contains primary seed germination records for 1,146 herbaceous plant species native to temperate Europe, compiled from 18,596 laboratory germination tests. For each seed lot, the dataset reports the number of seeds tested, the number of germinated seeds, and the environmental conditions...

| Sumario: | This dataset contains primary seed germination records for 1,146 herbaceous plant species native to temperate Europe, compiled from 18,596 laboratory germination tests. For each seed lot, the dataset reports the number of seeds tested, the number of germinated seeds, and the environmental conditions applied during each test, including mean temperature, alternating vs. constant temperature regimes, light vs. darkness, and the application of cold stratification, warm stratification, or seed scarification. Seed germination data are combined with global naturalization data (naturalization occurrence and geographic extent) with the aim of evaluating whether the naturalization success of native European herbaceous species is related to their germination responses to key environmental cues, in different macroclimatic zones. Using this dataset, we found that species that have become naturalized globally exhibit higher germinability, germinate at lower temperatures, and respond more strongly to seed scarification than species that have not naturalized. These traits are also positively related to the geographic extent of naturalization in temperate, tropical dry, and tropical humid regions worldwide. |
