Seed germination strategies reveal naturalization potential: Global insights from European herbaceous species

This dataset includes primary seed germination records for 1,146 herbaceous species native to temperate Europe, derived from 18,596 laboratory tests. For each seed lot, the dataset reports the number of seeds tested, the number of germinated seeds, and the conditions under which each test was conducted: temperature, alternating temperature, cold and warm stratification, light, and seed scarification. For each species, the dataset also provides biogeographic information on global naturalization occurrence and extent, and on the number of regions where naturalization has been reported in each of three macroclimatic zones: temperate, tropical dry, and tropical humid regions. Information on seed origin, seed lot identifier, contributor, and country of collection, and the country where each test was carried out, is also provided. The dataset allowed us to test whether seed germination traits, in terms of their responses to different germination cues, are related to the naturalization success..., , # Seed Germination and Global Naturalization Dataset

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, ...,
