The sample trees from two stands managed by different management systems - shelterwood and selection systems, and two generations within each stand, were compared. The evaluation of the potential acidity and conductivity of dry-mass extracts (KSE) proved an adverse effect of environment on the maternal stand in the shelterwood forest. The KSE-values are systematically higher in samples taken from the young as well as mature sample trees in the selection forest. Despite the limited duration and extent of the investigations, a better ecological stability of the selection forest as compared with the shelterwood one was observed.
Afficher plus [+] Moins [-]Air pollutants of SO2 and total potential deposition of sulphur of the forest territory Moravian-Silesian Beskids Mts. [Czech Republic] in 1996
1998
Hadas, P. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
According to the geostatistical methods annual sums of precipitation, mean annual concentrations of SO2, total potential deposition of sulphur as inputs to the mountain forest ecosystem of Moravian-Silesian Beskids on the spatial level in 1996 were derived. For this purpose, all possible meteorological and monitoring stations in the surroundings of the cesearch teiritory were used.
Afficher plus [+] Moins [-]Use of epicuticular waxes changes for detection of latent forest decline
1998
Bednarova, E. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic). Ustav Ekologie Lesa)
The aim of this study was to obtain data for elaboration of methods that would be suitable for detection of assimilative apparatus damage, if the damage is still in its latent phase. The needles are covered with epicuticular waxes, which have a protective function, but are also damaged by air pollution first.
