The paper addresses the quantification of local expenditures required for the calculation of the local multiplier score. The analysed economic indicators were the local expenditures of Training Forest Enterprise Masaryk Forest Křtiny (TFE MF Křtiny) for suppliers and employees in the individual forest districts for 2014. A part of the results is the calculation of a score for local multipliers 2 and 3 for the forest districts of TFE MF Křtiny for 2014. The local multiplier is a specific microeconomic indicator allowing the quantification and evaluation of socioeconomic benefits of the chosen entity especially for local residents and entrepreneurs. The results will allow assessing the effect of special-purpose forest enterprises and forestry on the economic and social development, and determining potential cash flows associated with the fulfilment of the socioeconomic functions of forest ecosystems in the area of interest of TFE MF Křtiny.

The Delphi screening method was used to select the most relevant criteria and sub-criteria to the forest park problem. Using the FAHP weighting approach, the weight of each criterion and sub-criterion was calculated. Then, the suitability map of forest park location was mapped by the weighted linear combination (WLC) method. The results revealed that 7 criteria (climate, water resources, physiography, landscape, vegetation cover, wildlife and economic criteria) and 16 sub-criteria received the required values and can be involved into the decision-making process of the forest park site selection problem. Using the derived weights of sub-criteria by FAHP and the WLC method, the final results showed that most of the study area is moderately suitable for the forest park location problem. The results of this study can be valuable in the planning of local forest park and future land use planning.

In this study Dijkstra's algorithm that consisted of nodes and links was used to optimize the road path in a broadleaved forest. The lower the cost, the greater the chance that the link will get routed. The road construction cost depends on the length of links, longitudinal gradient of links, side slope of the terrain and unit cost of the link construction. In general, the construction cost of each link increased with increasing length of the link, side slope gradient and longitudinal gradient. The total length and mean construction cost of optimal path were 530 m and 18.18 USD.m-1, respectively. Based on the analysis, we found that Dijkstra's algorithm is feasible in selecting an optimal path according to the construction cost of forest road.

Mey. seeds using a nano priming technique with multi-walled carbon nanotubes Abstract: To evaluate the effects of nano priming on seed germination of Alnus subcordata (Caucasian alder) C.A. von Meyer under drought stress, the present research was conducted using multi-walled carbon nanotubes (MWCNTs; 0, 10, 30, 50, and 100 mg.l-1) at 6 levels of drought stress (0, -2, -4, -6, -8, and -10 bar) through a factorial experiment (5 priming levels with 4 replications). After priming, the seeds were placed into a germinator at 21°C. Results revealed that nano priming at the concentration of 100 mg.l-1 led to the highest germination rate and percentage at all levels of drought stress. Also, the highest values of seed vigour index and root and stem lengths and dry weights were observed at nano carbon treatment with 30 mg.l-1. Considering the obtained results, it was concluded that nano priming could result in boosted resistance of Caucasian alder seeds against drought stress, so that the seed tolerance increased from -4 bar (without nano priming treatment, i.e. reference sample) to -8 bar upon applying 100 mg.l-1 nanotubes. Based on the results of the present research, it is suggested that the seed nano priming technique with MWCNTs can be applied in order to increase the seed and seedling tolerance of other members of the genus Alnus Miller.

Steyaert and Truncatella hartigii (Tubeuf) Steyaert isolated from some species of the genus Pinus L. in morphological characteristics of conidia and appendages Abstract: The similarity of and differences between the fungi Pestalotiopsis funerea (Desmazières) Steyaert and Truncatella hartigii (Tubeuf) Steyaert that damage the needles of the host plants Pinus ponderosa Peter & Charles Lawson, Pinus coulteri D. Don and Pinus nigra Arnold planted in Mlyňany Arborétum, were evaluated with emphasis on comparison of the morphology of their conidia and appendages. Conidia of P. funerea were fusiform to ellipsoid, straight to slightly curved, 4-septate with 3 (4-6) apical sometimes branched appendages. The basal cell was short, hyaline, obtuse and thin-walled with basal, hyaline, filiform, straight, unbranched and single appendage. Conidia of T. hartigii were fusiform, 3-septate, without basal appendages. 2-3 apical appendages arising from the apical cell were attenuated, flexuous, sometimes dichotomously branched. The highest occurrence of the fungi P. funerea and T. hartigii indicates the influence of biotic stresses on properties of these pine trees.

Karsten) seedlings. The seedlings were planted in a forest nursery in 5 different treatments: 4 treatments with the Bio-Algeen® product in different regimes (soaking, granulate, soaking + granulate, irrigation) and control. Compared to the control, mycorrhizal characteristics of the treated seedlings differed significantly for soaking treatment only, but they were less favourable for all treatments with this product. Among the growth characteristics, the height of aboveground parts was significantly taller compared to the control for soaking and granulate treatments, while the shoot dry weight was significantly higher for granulate treatment only. Both of these characteristics showed higher values across all treatments compared to the control. Although treated seedlings showed worse mycorrhizal characteristics, their growth was not affected by these characteristics. Thus, Bio-Algeen® can be used for an improvement of seedling growth in forest nurseries.
