Overall allele frequencies of soil seeds and mature plants showed significant differences between life history stages in both years, but not within years in soil seeds as well as mature plants stages. While mature plants showed a significantly greater amount of single and multilocus heterozygosity in both consecutive years, comparison between years did not yield any significant differences. In the same way, despite a relatively large seed bank the species population genetic parameters, i.e. allelic richness (A), observed heterozygosity (Ho), gene diversity (Hs), inbreeding coefficient (FIS) and fixation index (FST), did not change over years between as well as within life history stages. The soil seeds and mature plants significantly differed in Ho, Hs and FIS, while the A and FST were not significantly different between life history stages.
