Germination of European acorns: Data from 93 batches of 12 Quercus species

Abstract

We present a dataset of 93 acorn batches from 12 European Quercus species on which 8-week germination tests have been carried out. In addtion, seed mass and moisture content were measured. Information on collection locations, methods and dates is provided in order to correctly analyze the data. This database can be used to: (1) analysing the differences between species or populations at acorn/germination level, (2) assess the effect of acorn weight and moisture content on germination probability, (3) contrast the results of seeding in the field with the intrinsic germination capacity of acorns and, therefore, assess the limitation on germination imposed by environmental factors in the field, (4) help estimate the amount of acorns required to obtain a certain number of seedlings for both, direct-seeding operations in the field and sowing in the nursery.
