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 (R _S), observed heterozygosity (H _O), gene diversity (H _S) and inbreeding coefficient f(F _IS) 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.
