    Frost cracks and their effect on the stability of birch stands in the Kru?né hory Mts.

  • Original language description

    Frost cracks which originated in birch due to bending during long- term icing in winter 1995/1996 became the place of entrance for the attack of birch stems by Piptoporus betulinus (Bull. ex Fr.) Karst and subsequently for one of the causes of birch stand disintegration in the Kru?né hory Mts. The hypothesis is substantiated on the basis of regularities of the frost crack dispersion in the stem profile, frequency of occurrence related to the stand age, altitude and cardinal points. The number of frost cracks increased with the transect profile altitude 700--850 m. One crack on the birch stem predominated (73%) while the higher number of frost cracks occurred at altitudes 800 m. In stands younger than 20 years, frost crack damage was higher (34--47%) than in older stands (14%). Frost cracks occurred in the lower part of stems with the highest bending stress.

  • Czech description

    Hypotéza. ?e mrazové trhliny, které vnikly na bříze v důsledku ohnutí při dlouhodobé námraze v zimě 1995/1996 se staly vstupním místem pro napadení kmene březovníkem obecným (Piptoporus betulinus (Bull. ex Fr.) Karst a následně jednou z příčin rozpadu porostů břízy ve vy??ích polohách Kru?ných hor je zdůvodněna na základě stanovené zákonitosti disperze mrazových trhlin v profilu kmene, četnosti výskytu v závislosti na věku porostu, nadmořské vý?ce, světových stranách.
