The given index ranks among the indices of fourth-generation evaluation emerging from the value-based management theory. When calculating the index, we took the financial statements of a chosen forest enterprise for our starting point. On the basis of the calculated results we can state that the index development in the enterprise had an increasing tendency during the period 2011-2013. Recognised values of the index were positive, i.e. the enterprise reached a positive market value for the enterprise owners.

The best conditions for shoot induction and growth were with 6-benzyladenine at 1.0 mg.l-1. For axillary shoot proliferation, the excellent result was obtained using 2.0 mg.l-1 meta-topoline. Well-developed shoots (more than 2 cm in length) were successfully rooted ex vitro at 82% by treatment with commercial rooting powder (2% indole-3-butyric acid; Rhizopon®). Rooted plantlets were acclimatized in the greenhouse and the survival rate of transplantation reached 80%.

L.) on the Polná demonstration plot (Czech Republic) up to the age of 15 years Abstract: Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristics of cherry trees were determined each year during the period 2000-2010. At the age of 15 years, the progenies reach mean heights of 4-9 m and diameter at breast height (DBH) of 5-10.5 cm. The determined differences in height and DBH between progenies are statistically significant. Cherry trees of generative origin and progeny of clone No. 14 grow markedly slower in comparison with clones Nos 24, 26 and 28. The values of growth characteristics for verified clones are comparable with similar findings from abroad. The in vitro plantlets of wild cherry achieve similar growth characteristics as generative seedlings.

Representative research plots were selected in forest ecosystems with natural species composition and spatial structure (small-scale strictly protected areas) as well as in forest ecosystems with altered tree species composition and spatial structure. Research was conducted in three altitudinal vegetation zones (AVZ): in 2nd communities of Fagi-querceta s. lat. (beech-oak forests), 3rd Querci-fageta s. lat. (oak-beech forests) and 4th Fageta abietis (beech forests with fir). Research plots are situated at altitudes ranging between 275 and 540 m a.s.l. In the 2013 growing season, totally 3,474 imagoes and 2,532 nymphs of 32 psocid species were collected. Of those, 748 imagoes of 25 psocid species were collected in Fagi-querceta. The occurrence of Caecilius burmeisteri, Caecilius flavidus and Graphopsocus cruciatus was eudominant. 2,194 imagoes of 23 psocid species were found in Querci-fageta, eudominant were there Caecilius flavidus and Caecilius burmeisteri. 532 imagoes of 18 psocid species were found in Fageta abietis, eudominant were there: Caecilius flavidus, Peripsocus subfasciatus and Caecilius burmeisteri. In respect to the species composition, 3rd AVZ and 4th AVZ are similar to each other while 2nd AVZ is less similar.

In July, mycorrhizal inoculation had no significant effect on stem growth and volume production of black and white poplar plants grown on polluted and non-polluted soils. In October, mycorrhizal inoculation improved only parameters of white poplar plants (survival on polluted soil; growth and volume production on polluted and non-polluted soils). Mycorrhizal inoculation increased the root colonization percentage of black and white poplar plants on both soils. Generally, black poplar plants had significantly better survival, root mycorrhizal colonization, stem growth and volume production than white poplar plants. Although mycorrhizal and non-mycorrhizal plants of black poplar on polluted soil had higher survival, growth and volume production than white poplar, however in white poplar mycorrhizal inoculation improved the efficiency of plants on polluted soil.

Effects of thinning on (i) diameter and height increment of the remaining sprouts in polycormons, and (ii) soil moisture were studied one year after thinning. The experiment was carried out in the southeastern part of the Czech Republic. Thinning reduced 50% of the total stump basal area per polycormon. One to five dominant sprouts were left. Results showed that thinning significantly increased diameter increment of sessile oak (59%) and European hornbeam (61%). However, thinning did not increase height increment of sessile oak and European hornbeam. Diameter increments of sessile oak and European hornbeam were not different. Height increment of European hornbeam was 30% higher than that of sessile oak in thinned plots and 53% higher in unthinned plots. Soil moisture increased significantly in thinned plots.

Among other things, monitoring and analyses of work conditions and workload help reduce possible risks, injuries and long-term illnesses caused by occupational stress. The interim results of the presented ergonomic study describe and analyse the course of physical load upon performing selected work operations at the stage of timber harvesting in laboratory conditions at the harvester simulator. The authors study particularly the relations between independent variables (work operations) and dependent variables (pulse, respiration and muscle tension). The diagnostic system Biofeedback 2000x-pert is used for measuring and recording changes in dependent variables. Results presented in this study analyse the obtained differences in measurements of physical and mental load in operators in individual work operations. The null hypothesis about the non-existence of a difference between the working operations from the viewpoint of the monitored variables can be refused. Therefore we can accept the hypothesis stating that there is a significant difference between individual working operations.
