Five plots were established % three in Pinus nigra (Arnold) stands and two in Pinus sylvestris (L.) stands. On each plot, the 19-20 most vigorous dominant or codominant trees with a minimum diameter at breast height (DBH) of 20 cm were selected and their resin yield analysed in 2012. Resin yield in P. nigra was considerably higher than that in P. sylvestris. The average resin yield per tree during the study period of 102 days was 1.144 kg for P. nigra and 0.612 for P. sylvestris. There were substantial differences in resin yield among individual trees in the study period: 0.336-2.487 kg for P. nigra and 0.249-1.270 kg for P. sylvestris. The resin yield in P. nigra was considerably higher for the trees with larger DBH, while this was not the case in P. sylvestris. Tree species was the most important factor in resin yield. Increased precipitation resulted in higher resin yields on most plots, whereas better site productivity positively affected resin yield on all P. nigra plots but not on P. sylvestris plots</dc:description><dc:description xml:lang="sl">Namen naše raziskave je bil proučiti vpliv različnih dejavnikov na proizvodnjo borove smole na Krasu v Sloveniji. Za ta namen smo določili 5 raziskovalnih ploskev, in sicer tri ploskve v sestojih črnega bora (Pinus nigra Arnold) in dve v sestojih rdečega bora (Pinus sylvestris L.). Proizvodnjo smole smo spremljali v letu 2012, ko smo na vsaki ploskvi izbrali 19 % 20 dominantnih ali kodominantnih dreves z minimalnim prsnim premerom 20 cm. Analiza je pokazala, da je proizvodnja smole pri črnem boru značilno večja kot pri rdečem boru. Povprečna količina smole na drevo v času periodičnega spremljanja 102 dni je pri črnem boru dosegala 1,144 kg in pri rdečem boru 0,612 kg. Variabilnost v proizvodnji smole je bila znotraj vrste velika, pri črnem boru med 0,336 % 2,487 kg in pri rdečem med 0,249 % 1,270 kg. Pri črnem boru je bila količina proizvedene smole v pozitivni povezavi z debelino drevesa, medtem ko pri rdečem boru te odvisnosti nismo potrditi. Na količino smole pri črnem boru pozitivno vpliva produktivnost rastišča. Ugotovili smo, da na smoljenje črnega bora pozitivno vpliva količina padavin, medtem ko višje dnevne temperature dnevni donos smole zmanjšujejo</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-LKTD6Q5B"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-LKTD6Q5B" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-LKTD6Q5B/fb99aa18-a58b-48f5-a44a-318540669e54/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Gozdarski inštitut Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-LKTD6Q5B/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-LKTD6Q5B" /></ore:Aggregation></rdf:RDF>
