Clonal Variation in Susceptibility of White Birches ( Betula Spp.) to Mammalian and Insect Herbivores
Abstract Resistance of small micropropagated plantlets and seedlings of white birch (Betula pendula Roth and B. pubescens Ehrh.) to hares (Lepus timidus L.), voles (Microtus agrestis L.) and weevils (Phyllobius and Polydrosus spp.) was determined. Field and cafeteria experiments were conducted over...
