Determination of soil hydrolimits in spruce stand soil profile in the Beskids Mts. [Czech Republic]
1998
Novak, F. | Kalcik, J. (Akademie Ved, Ceske Budejovice (Czech Republic). Ustav Pudni Biologie) | Rauch, O.
The soil water retention potentials and other hydrolimits of individual soil horizons of podzolized soil were determined in the stand of Picea abies (Mecuvka, the Beskids, Czech Republic) on godulic sandstone. Different hydropedologic characteristics for the individual soil horizons were found. Extreme values were detected for the albic E horizon, which importance for water and nutrient status of forest stand on podzolic soil is discussed.

Natural regeneration of beech under ecologically difficult conditions
1998
Penaz, J. | Martinek, J. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic). Fakulta Lesnicka a Drevarska)
In the region of Knehyne-Velka Stolova in the Moravian-Silesian Beskids, where there are ecologically difficult conditions for functioning forest ecosystems, possibilities were studied for the naturat regeneration of beech. The study of problems was particularly related to generative propagation, however, cases of vegetative propagation were also found. Potential possibilities of regeneration are related to the seed year 1995. Rooting ability of layered branches or lying beech trees wes studied. Analysis is given of a rooting beech branch.
Afficher plus [+] Moins [-]Long-term influence of enhanced UV-B irradiation on photosynthetic characteristic of Norway spruce (Picea abies) in the conditions of the Beskids Mts. [Czech Republic]
1998
Sprtova, M. | Marek, M.V. (Akademie Ved, Brno (Czech Republic). Ustav Ekologie Krajiny)
The cloned saplings of Norway spruce (7 years old) were exposed to ambient UV-B irradiation or enhanced BV-B irradiation (+25 %) continuously over three growing seasons. Comprehensive analysis of CO2 assimilation and chlorophyll a fluorescence was performed at the end of the third growing season to evaluate the influence of enhanced UV-B irradiation. The analysis resulted in observations of decreased photosynthetic activity, mainly of RUBISCO activity, as a result of long-term influence of enhanced UV-B irradiation. Morever, the deep impact of enhanced UV-B irradiance on the level of electron transport and thus enhanced sensitivity to photo-inhibition was demonstrated.

Norway spruce increment as related to the type of branching in the Moravian-Silesian Beskids Mts. [Czech Republic]
1998
Hauck, O. | Palat, M. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
Data necessary for the determination of the proportion of various types of branching in stands under study, their variability within a tree, accuracy of classification of the type of branching, damage to particular types of branching due to breakage and initial age for their reliable recognition were obtained according to method from 1,336 trees situated in 11 trial plots in the region of the Beskids. Statistically significant differences were determined in the diameter and height increments for particular types of branching.

Vavricek, D. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
Surface liming even in higher doses did not affected soil Ph and improving the content of Mg and Ca was only temporary. Spot fertilization by fine-ground amphibolite is significant particularly from the aspect of long-term affects. Short-term affects manifested themselves slightly but in the whole system of particular parameters. Application of higher amounts (3 kg.ha-1) of amphibolite has its substantiation in the future.
