Germination was tested at the University of Granada following international protocols with 8985 acorns from 93 batches and 16 countries across Europe. Data on germination probability, acorn origin, mass, and moisture content measured on another 4544 acorns are available at https://doi.org/10.30827/Digibug.87318. Associated metadata are available at https://metadata-afs.nancy.inra.fr/geonetwork/srv/fre/catalog.search#/metadata/a742c6d8-bc37-4ca2-8b81-2447c5a8858d.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article1297-966Xhttps://doi.org/10.1186/s13595-024-01267-2https://annforsci.biomedcentral.com/articles/10.1186/s13595-024-01267-2#citeasopen access581.5581.142630*2AcornGermination testSeedlot germination potentialSeed massSeed moistureSeed viabilityFisiología vegetal (Biología)Ecología (Biología)2417.19 Fisiología Vegetal2417.13 Ecología Vegetal3106.08 Silvicultura
