Iniciální výzkum náchylnosti smrku ztepilého k napadení lýkožroutem smrkovým z hlediska dlouhodobého působení stresových faktorů / Initial study of predisposition of Norway spruce to bark beetle attack in relation to long term effects of multiple stress

KOTRC, Miroslav January 2014 (has links)
This thesis is a contribution to understanding of predisposition of solitary Norway spruce (Picea abies [L.] Karst.) to bark beetle (Ips typographus (L.)) attack. The predisposition is estimated from long term effects of multiple stress, which are determined by tree crown transformation. By virtue of created model, it was documented that some environmental variables could have considerable effect on tree crown transformation. Tree crown transformation is generally considered a mirror of spruce health status.
