To identify factors affecting the natural regeneration of A. koreana, we examined role seed pathogens overwintering survival seeds seedbeds on Mount Halla, In September 2003, were placed following three types sites: Sasa dominated, shaded by rocks, or forest floor; then recovered from beneath snow cover April 2004 and analyzed for occurrence harmful microfungi. Racodium therryanum Thuem. was fungus most often isolated retrieved also detrimental eight fungal tested a pathogenicity trial. vitro, R. caused total loss germination ability at 0 °C after 100 days. The infection rate negatively correlated with rate. highest fl...
