Data from: Microgeographic variation in early fitness traits of Pinus sylvestris from contrasting soils

Seedling phenotypic data from two Iberian Pinus sylvestris provenances from contrasting soils (calcareous vs. siliceous) grown in a 3-year greenhouse experiment on both types of natural local substrate. Each line in the file corresponds to a different seedling. Phenotypic variables as described in the original paper published in American Journal of Botany, doi 10.1002/ajb2.16159
