Summary of population genetic characteristics of Pinus strobus populations at which fine scale genetic study was performed.

Number of individuals of Pinus strobus collected and analysed (No.) at different localities in the Czech Republic, average number of alleles per locus (A), allelic richness (RS), observed heterozygosity (HO), gene diversity (HS) and inbreeding coefficient f(FIS) according to [77] for 10 microsatellite loci of four recognized age classes – “old trees” (50 years old and older), “mature trees” (between 21 and 49 years old), “saplings” (between 6 and 20 years old) and “seedlings” (trees not older than 5 years) computed by Arlequin and Fstat. All populations significantly deviated from the Hardy-Weinberg equilibrium calculated using 50,000 permutations in Fstat.
