%0 Journal Article %T Root system development of European beech (Fagus sylvatica L.) after different site preparation in the air-polluted area of the Kru n¨¦ hory Mts. %A Old£¿ich Mauer %A Eva Pal¨¢tov¨¢ %J £¿asopis Beskydy %D 2011 %I Mendel University, Brno %X The paper analyzes the development and health condition of root system in European beech aged 8--10 years, planted in the Kru n¨¦ hory Mts. within the framework of reconstructions on plots prepared by various technologies before the establishment of substitute tree species stands. Root systems from natural regeneration in the Kru n¨¦ hory Mts. and beech trees planted in the Bohemian-Moravian Upland served as controls. Only a third of trees from the natural regeneration developed a taproot. Planted between non-spread mounds, all beech trees developed a superficial root system. In other stands, a half of the trees had a root system with substitute taproots and a half of the trees had a superficial root system. No material differences were found in the development of the root system between beech trees in the Kru n¨¦ hory Mts. and those in the Bohemian-Moravian Upland. Even in the Kru n¨¦ hory Mts., the beech can be regenerated on screened localities sized up to 0.50ha. %K European beech %K root system %K Ore Mts. %K reconstruction of substitute tree species stands %K natural regeneration %U http://www.mendelu.cz/dok_server/slozka.pl?id=57763;download=88744
