"Based on an analysis of 114 root systems and stems of European mountain ash at the age of 15-50 years in the air-polluted region of the Kru\u0161n\u00E9 hory Mts. it was found out that in Forest Altitudinal Zone 7 the mountain ash forms only a superficial root system with its roots penetrating only to the humus and humus-influenced soil horizons. In all lower forest altitudinal vegetation zones the mountain ash forms an anchoring root system with anchors penetrating as deep as to about 120 cm. Although it appears that the reason for the formation of the superficial root systems in Forest Altitudinal Zone 7 is a periodically high reaching groundwater table, an adverse effect of detected changes in the chemism of some surface soil horizons cannot be excluded. No variance was found out in the vitality and biomass of fine roots between the trees growing in FAZ 7 and the trees growing in lower altitudinal vegetation zones."@en . . .
