In Serbia, V. album most commonly occurs as a sub-species (Viscum album subsp. abietis (Wiesb.) Abrom), which grows on branches and stems of European silver fir trees (Abies alba Mill.). In spring 2011, chlorotic mistletoe shrubs with numerous fruiting bodies on the leaves and stems were observed on A. alba trees in mixed fir and beech stands on Mt. Goč in Central Serbia. Symptomatic shrubs were collected, fruiting bodies were removed with a sterile needle and plated on MEA (malt extract agar). Two weeks later white, moderately slow-growing fungal colonies with undulated margins and a rosette-like appearance were obtained and the aim of this study was to identify these isolates. Based on morphology of the asexual morph and phylogeny of DNA sequence data for the internal transcribed spacer (ITS), tran...

Because of its attractive narrow crown and drooping branches, P. omorika is a highly valuable ornamental tree used for screening in green areas and homes in Serbian, northern European and North American cities. In recent years, natural populations of P. omorika trees at Mt. Tara in the Western Serbia and trees planted in the urban areas have exhibited resinous branch cankers followed by die-back of stems and branches and a needle fall. Samples of symptomatic tissue were collected across Serbia from 2009-2014. The most prevalent fungal colonies obtained from diseased parts resembled those of the Botryosphaeriaceae spp. (Ascomycota: Botryosphaeriales) and the aim of this study was to identify them.

About 30% of surveyed trees showed different stages of decline. Different proportions of C. parasitica morphotypes (normal/orange, intermediate, white) were detected when isolates were grown on agar media in the laboratory. About 57% of isolates showed normal pigmentation suggesting virulence, while 42% showed intermediate morphology. Less than 1% (or five isolates) was identified as hypovirulent based on detection of dsRNA of virus. Five European vegetative compatibility (vc) groups, EU-1, EU-2, EU-3, EU-10 and EU-12 were identified in four districts (Pogradec, Tropoje, Tirana and Elbasan) with dominant chestnut forests. EU-12 was the dominant vc type making up 39% of isolates studied. Transmission of dsRNA between virulent and hypovirulent isolates was successful in laboratory conditions. Biological control using hypovirulent strains to inoculate virulent cankers on chestnut trees in the field yielded between 46 and 84% of heavily calloused cankers, while around 30% of healthy trees that had not been inoculated produced heavily calloused cankers, suggesting natural spread of hypovirulence.

Vegetative propagation makes them suitable for establishing highly productive plantations along big rivers and in flooded plains. The production of large quantities of biomass provides a good substrate for various organisms. The aim of this study was to identify fungal species occurring in the poplar plantations in Serbia and to determine their frequency and role in decomposition of tree parts. Fifty species belonging to the divisions Ascomycota, Basidimycota and Deuteromycota as well as two species from Oomycota (the genus Phytophthora) were reported. Bark was the substrate for 27 species, 14 species were found on leaves and 9 species were wood-decaying fungi.

In Serbia, Phytophthora species were iso-lated from rhizosphere soil in declining, as well as apparently healthy stands. After detailed morphological and molecular identification, several Phytophthora species were confirmed. The most common pathogen of fine roots in Serbian European beech stands was Phytophthora plurivora Jung and Burgess. This species was characterized as homothallic, semipapillate, produces sporangia of various shapes, and has an optimum temperature for growth at around 25ºC.P. plurivora occurred on 58% of positive samples, followed by P. cambivora (Petri) Buisman at 17%, P. gonapodyides (Petersen) Buisman at 8%, with other unidentified species accounting for the remaining 17%. A pathogenicity test performed with P. plurivora and young beech germinants from ten Polish beech provenance...

The material was collected from ca. 250 permanent plots, established for monitoring forest health, and from forests and orchards attacked by Armillaria. A. mellea s.s. occurred on several coniferous and broadleaved trees in most areas examined, although it was absent above 1100-1200m in northern Albania. This species damaged Abies and Quercus spp. and, to a lesser extent, other forest trees. A. mellea was also commonly recorded causing damage in orchards and vineyards. A. gallica was a common saprophyte or weak pathogen in coniferous and deciduous forests at altitudes from 600 to 1600m, and less commonly on oaks at lower altitudes. A. ostoyae was rare in central and southern Albania, but common in northern Albania, causing significant damage to pine and other conifers, mostly at altitudes from 600 to 1800m. A. cepistipes was recorded at altitudes from 800 to 1800m as a saprophyte or weak pathogen on conifers and deciduous trees, mostly in beech and silver fir forests. A. tabescens was found in oak forests at altitudes from sea level to 900m. In orchards, A. tabescens occasionally attacked almond and pear trees. A. borealis was found in a few locations in northern Albania, at altitudes from 800 to 1800m.

Since the Western Balkan countries have a very rich biodiversity, collection and use of NWFPs have a long tradition in this region. Although in the last few years in the region a number of modern laws and regulations in the field of forestry, which in some articles regulate NWFPs have been adopted, it is important to emphasize that these products are issues of laws in other areas, particularly the laws on nature and environmental protection. The research is based on a review and comparative analysis of laws and regulations in the field of forestry, nature conservation and environmental protection in the selected countries of WB. Goal of this paper is to determine legislative points governing the area NWFPs through examination and analysis of laws and other legal documents in WB.

The objective of this article is to profile the plantation poplar industry in Serbia through the supply chain from the forest to manufacturing and to end-use markets. Each step in the supply chain will be examined to identify current and potential poplar wood products, origin and quality of logs, mill processing capabilities, and market drivers. In addition, supply chain dynamics will be examined for the 2008-2012 period. By examining the recent past and the present, this study offers a perspective on improving market development for plantation poplar in Serbia. There have been surveyed 27 companies purchased a total of approximately 282,000 m3 of poplar annually, which is about 90%. All processors companies for poplar wood processing are privately owned. The capacities of all are on average about 17,300 m3•yr-1 and the utilization of the installed capacities is app. 66%. Ser...

Various Chamaecyparis cultivars (e.g. „Columnaris”, „Ellwodii”, „Alumii”) are also important conifers propagated in Serbian ornamental nurseries. In recent years, false cypress trees have exhibited top die-back and branch flagging accompanied by resin bleeding on the main stems or at the bases of dead shoots or branches. Diseased trees of all ages and seedlings were sampled from 2009-2014 and the most common fungi isolated from symptomatic samples were species of the family Botryosphaeriaceae. The aim of this study was to identify these fungi as part of a larger project to isolate and identify the Botryosphaeriaceae as potential pathogens of landscape trees in the Western Balkans. Isolates obtained were identified using anamorph morphology and comparisons of DNA sequence data for the internal transcribed spacer (ITS), translation elongation...
