Full textKosovo’s forest products industry is a very important part of Kosovo’s economy and within the present work data was collected through a survey of all sawmills in Kosovo and information gathering from the Ministry of Agriculture, Forestry and Rural Development of Kosovo. The forest resources and sawmill structure of Kosovo were analyzed and the availability of different species of wood in different regions of the country established. In parallel, the study of one home grown wood species, Quercus cerris, was conducted in order to improve its use in sawmilling to produce value added wood components. For this purpose, ten Quercus cerris trees, grown in two sites in Kosovo, were felled and discs taken at different stem height levels. Relevant data for this species was obtained on stem quality, including heartwood, sapwood and bark development as well as ring analysis. Chemical and durability characterization was also conducted together with the evaluation of density and Brinell hardness. Quercus cerris from Kosovo showed good potential as a timber species for the supply of stem wood to the saw-milling industry allowing good yields of heartwood-only sawn wood components. Taking into account the good technological properties measured together with the apparent low level of extracts and the low durability class against subterranean termites, interior or protected uses are highly recommended. The bark should also be considered for complementary valorization. Furthermore, based on the worked developed, a curricular programme combining scientific and technological knowledge for industrial management, communication knowledge and creative work was developed in close cooperation with wood processing enterprises in Kosovo, and with the Kosovo Wood Processing Association. Recommendations were also provided for further development of the forest and sawmill industry

Full textEste trabalho teve como objetivo caracterizar a madeira de Quercus cerris e para tal realizaram-se os seguintes estudos: quantificação do cerne, borne e casca, caracterização da composição química da madeira de cerne e durabilidade natural do cerne. Os estudos incidiram em amostras de madeira de árvores de Q. cerris abatidas em duas regiões do Kosovo com classes de idade de 70 a 80 anos. Todas as árvores de Q. cerris apresentaram formação de cerne, com um contorno regular e cor castanha avermelhada distinta do borne de cor castanha mais clara. A área de cerne diminuiu da base para o topo e ao nível do DAP foi em média 57,2% e 43,2% nos dois locais. A espessura de borne variou entre 3,2-4,2 cm e 3,6- 4,6 cm para as árvores dos dois locais. O cerne do Q. cerris apresentou uma correlação positiva com o diâmetro do tronco enquanto a largura de borne foi independente do diâmetro das árvores. O teor médio de casca foi de 14,2% e 16,3 % em % da área total com casca. A composição química média da madeira de cerne Q. cerris foi: cinzas 0,93%, extrativos totais 6,7% e lenhina total 26,4%. Quanto aos polissacáridos eles são constituídos principalmente por glucose e xilose (respetivamente em média 60,7% e 32,2% dos monómeros). Os ensaios de durabilidade natural face ao ataque de térmitas subterrâneas, permitiram classificar a madeira de cerne de Q. cerris como não durável. Face a estes resultados, conclui-se que para a utilização da madeira de cerne de Q. cerris deve considerar-se a sua baixa resistência biológica

Full textThe impact of water deficit and recovery on physiological features of the black poplar clones, as well as of the oaks populations were analyzed. The aim of this research was to indicate the potential of the studied genotypes for survival under changing environmental conditions, in accordance with current climate changes, which include the reduction in amount of rainfall and limited water availability. Obtained results have shown a specific variation of studied morpho-anatomical, physiological and biochemical parameters which depended on soil humidity on the applied treatment (control, drought followed by recovery and permanent drought), as well as on plant genotype.Water deficit on permanent drought treatment had little negative effect on plant growth of poplar clone X/32, as well as oak populations L1 and C1. Plant height stress tolerance index also confirmed good morphological adaptation to drought of these genotypes. Stomatal index was not negatively affected by water deficit in oak plants. In both experiments, a permanent drought treatment led to the largest reduction in the values of gas exchange parameters in almost all genotypes.On the other hand, concentration of photosynthetic pigments was not considerably decreased in plants exposed to water deficit, as well as the parameter Fv/Fm, in most examined plants. Compared to the control, the impact of permanent drought treatment on biochemical parameters was expected, in the most cases. Compared to the control, proline content in leaves of most examined genotypes was significantly increased on permanent drought treatment, while nitrate reductase activity was significantly decreased.Examined genotypes exhibiting slight or no reduction in values of the most examined parameters during severe drought stress, could be used for afforestation in arid sites. Arid habitats appeared to be more numerous due to the effects of global climate changes.

Full textNo presente trabalho estudou-se a madeira de Quercus cerris (carvalho-da-Turquia) com origem em dois locais (Blinaja e Duboçak) do Kosovo, área caracterizada por possuir um clima continental. O estudo assentou em várias análises, tendo-se feito uma análise anatómica de vários parâmetros dimensionais dos vasos; um estudo dendroclimático, identificando sinais climáticos relevantes com recurso a técnicas dendrocronológicas e uma análise da dureza através da determinação da dureza de Brinell. Os resultados mostraram que ao nível da anatomia dos vasos o Q. cerris possui características semelhantes a outras espécies do mesmo género, como por exemplo o Q. faginea, verificando-se que com o aumento da idade o número de vasos tende a diminuir, enquanto que a frequência se mantém relativamente constante e a proporção apresenta um ligeiro aumento. Obtiveram-se relações significativas (p<0,01 e p<0,05) entre os vários parâmetros analisados. A análise dendroclimatológica efetuada demonstrou que, tal como acontece para o crescimento desta espécie em climas mediterrânicos, a precipitação do início da primavera do ano corrente e no mês de outubro do ano anterior tem influência no crescimento radial desta espécie, apesar da fraca qualidade das cronologias analisadas neste trabalho que não permitiram uma conclusão sólida quanto a estes fatores. Obteve-se um valor de dureza médio superior para a madeira da parcela de Blinaja (38,48 N.mm2) quando comparado com a parcela de Duboçak (33,90 N.mm2). Os valores obtidos permitiram classificar a madeira dos dois locais como apta para a utilização em todos os tipos de pavimento doméstico e em áreas comerciais com uso moderado

Full textThe present work studied the production and characterization of extracts rich in bioactive compounds (namely friedelin) from Quercus cerris cork. Soxhlet and batch solid-liquid extraction (SLE) with methanol, ethanol, dichloromethane and petroleum ether were carried out, as well as supercritical fluid extraction (SFE) using modified carbon dioxide (by addition of ethanol). The produced extracts were characterized by FTIR-ATR and GC-MS, and multidimensional scaling (MDS) was applied to compare them. The optimization of SFE was performed using Box-Behnken design of experiments and response surface methodology. The maximum total extraction yield (𝜂Total) was attained for the Soxhlet extraction with methanol (𝜂Total = 13.8 wt.%) and the minimum was attained in batch SLE with petroleum ether (𝜂Total = 0.35 wt.%). A significant variability of 𝜂Total values was evident, marked by the higher yields obtained with polar solvents, namely methanol and ethanol. For the supercritical fluid extractions, 𝜂Total ranged from 1.2 wt.% for run SFE3 (50 ℃, 2.5 wt.% EtOH, 5 g min−1) to 1.7 wt.% for run SFE4 (60 ℃, 2.5 wt.% EtOH, 8 g min−1). For friedelin concentration (𝐶Friedelin), the results ranged from 41.3 wt.% (Soxhlet with dichloromethane) to 5.4 wt.% (batch SLE with methanol). The best performing assays on 𝐶Friedelin were those involving weakly polar/non-polar solvents. The SFE assays provided 𝐶Friedelin results better than most Soxhlet and batch SLE experiments, which confirms the interesting selectivity to friedelin (𝛼F,nF). MDS analysis highlighted the chemical proximity between the alcoholic extracts and the biomass, and between the weakly or non-polar solvent extracts and pure friedelin. For the experimental optimization of SFE of Q. cerris cork, the conditions that maximize 𝜂Total (2.2 wt.%) and 𝛼F,nF (3.3 at t = 8.0 h) were the maximum values of 𝑇 (60 ℃), ethanol content (5 wt.%) and CO2 flow rate (11 g min−1). In fact, the selectivity values were higher than 1.0 anywhere within the studied experimental space, which shows that friedelin can be removed selectively over all the other compounds by SFE. For friedelin concentration, the maximum (𝐶Friedelin= 38.2 wt.%) was attained for the combination of a lower temperature (40 ℃), no cosolvent (0 wt.% EtOH) and lower CO2 flow rate (5 g min−1). The optimal conditions depend on what is the main goal of extraction: an extract enriched in a higher diversity of compounds (higher 𝜂Total) or in a target compound like friedelin (higher 𝐶Friedelin). On the whole, this work provides strong arguments towards the production of friedelin enriched extracts from Quercus cerris cork through SFE technology, under the biorefinery concept
