Reproduction strategies of the silver birch (Betula pendula Roth) at post-industrial sites

Abstract The study aimed to evaluate the parameters of reproductive traits, specimens’ fertility and reproductive efficiency observed in Betula pendula populations growing at different types of sites (zinc-lead heaps, coal mine heaps and unpolluted site). The leaf biomass and the biometric character...
