Abstract: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).

Title:Parametri branik dreves Pinus nigra (Arnold) in njihov klimatski signal
Abstract: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).
