20.500.12556/DiRROS-7756 Multiple tree-ring parameters from Pinus nigra (Arnold) and their climate signal Parametri branik dreves Pinus nigra (Arnold) in njihov klimatski signal The first exploration of climate signal in tree-rings of Black pine (P. nigra Arnold), using minimum blue intensity method, is presented. Sampled trees were growing on site Kojnik (Slovenia). For resin extraction and scanning, 5 mm thick cores were prepared. Whole tree-ring widths were measured, as well as the width and density of early- and latewood. To remove age trend and influence of non-climatic factors, raw measurements were standardized using spline function. In density measurements, highly significant correlation values were calculated between May-June summed precipitation and earlywood density (r = 0.64, p<0.001), while maximum latewood density correlates the best with mean June-August temperature (r = 0.42, p<0.01). In width measurements, the highest correlation was calculated between tree-ring width and mean June-August temperature (r = -0.62, p<0.001). Predstavljamo prvo analizo klimatskega signala v branikah črnega bora (P. nigra Arnold) s pomočjo metode odboja modrega spektra. Izbrana drevesa so rastla na Kojniku. Iz vzorcev debeline 5 mm smo ekstrahirali smolo in jih optično skenirali. Izmerili smo širino celotne branike ter širino in gostoto ranega ter kasnega lesa. Za odstranitev starostnega trenda in drugih ne-klimatskih faktorjev smo merjene časovne serije standardizirali s kubičnim zlepkom. Pri meritvah gostot smo značilne korelacije izračunali med padavinamiobdobja maj-junij ter gostoto ranega lesa (r = 0.64, p<0.001), medtem ko je gostota kasnega lesa v najboljši korelaciji s povprečno temperaturo obdobja junij-avgust (r = 0.42, p<0.01). Pri merjenju širin je bila najvišja korelacija med širino celotne branike in povprečno temperaturo obdobja junij-avgust (r = -0.62, p<0.001). branike klimatski signal metoda odboja modrega spektra črni bor Pinus nigra Kojnik suša true false true Angleški jezik Angleški jezik Znanstveno delo 2017-07-12 09:19:20 2017-07-12 09:19:20 2022-08-16 09:26:09 0000-00-00 00:00:00 2012 0 0 str. 15-25 Vol. 98 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*811:630*55:630*56:630*111:630*17(045)=111 0351-3114 URN:NBN:SI:doc-GKMKD3EN 3580838 6206978 RAZ_Poljansek_Simon_i2012.pdf RAZ_Poljansek_Simon_i2012.pdf 1 3BB6C4FF83DAA2950F47FFD9AEF947DB d6dc9822d1eacc6117a423c223a7ee5a9c7162a5b1c9f0e08df821f5225f2e37 27dde6ed-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/9ec135d1-c249-469b-8bd1-36200d134e96 https://dirros.openscience.si/Dokument.php?lang=slv&id=9621 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
