The aim of this paper is to present the results of research aimed at identifying the benefits of the forest enterprise for the local economy through calculation of the local multiplier score. 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...

The aim of this study is to solve the forest park site selection problem using a Fuzzy analytic hierarchy process (FAHP) framework in the Galegol Basin, Lorestan province, Iran. 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...

From an economic point of view a well-designed road path with the minimum construction cost is an optimal path that can be found using Dijkstra's algorithm. 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....

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...
Comparison of the fungi Pestalotiopsis funerea (Desm.) Steyaert and Truncatella hartigii (Tubeuf) Steyaert isolated from some species of the genus Pinus L. in morphological characteristics of conidia and appendagesOriginal Paper

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...

In this paper, the effect of the Bio-Algeen® product (bio-alginate from the seaweed Ascophyllum nodosum (Linnaeus) Le Jolis) was evaluated in relation to basic mycorrhizal and growth characteristics of Norway spruce (Picea abies (Linnaeus) H. 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...
