Abstract:Preučevanje razvojnih faz gozdnega drevja v dolgem časovnem nizu je vse pomembnejše orodje za ugotavljanje medsebojne odvisnosti vremenskih spremenljivk in z njimi povezanih bioloških odzivov. V naši raziskavi smo analizirali nastop fenofaz prvih listov in iglic ter splošnega rumenenja listja za listavce na 11 ploskvah intenzivnega monitoringa gozdnih ekosistemov v Sloveniji v letih od 2004 do 2011. Obravnavali smo fenofaze za dob (Quercus robur L.) na ploskvah Krakovski gozd in Murska šuma; bukev (Fagus sylvatica L.) na ploskvah Lontovž pod Kumom, Temenjak na Vinski gori, Borovec v Kočevski Reki, Fondek v Trnovskem gozdu, Gorica v Loškem Potoku; smreko (Picea abies (L.) Karst.) na ploskvah Kladje na Pohorju in Krucmanove Konte na Pokljuki; rdeči bor (Pinus sylvestris L.) na ploskvi Brdo pri Kranju; črni bor (Pinus nigra Arnold) na ploskvi Gropajski Bori pri Sežani. V povprečju je fenofaza prvih iglic (BGS) smreke nastopila na 166 julijanski dan. Za rdeči bor je BGS nastopila na 128 julijanski dan, za črni bor pa 149. julijanski dan. Fenofaza prvih listov (BGS) je za bukev v povprečju nastopila na 128, za dob pa 117. julijanski dan. Splošno rumenenje listov (EGS) za bukevje v povprečju nastopilo na 297, za dob pa 308. julijanski dan. Dolžina vegetacijskega obdobja (LGS) doba je bila v povprečju 75 dni daljša kot za bukev. Ugotavljamo, da se je v obdobju od leta 2004 do 2011 nakazoval zgodnejši nastop fenofaze prvih iglic (BGS) smreke, rdečega bora ter črnega bora na vseh obravnavanih ploskvah. Zgodnejši nastop prvih listov (BGS) bukve in doba smo zaznali le na posameznih ploskvah, ne pa vseh. Kasnejši nastop splošnega rumenenja listov (EGS) za bukev smo zaznali le na dveh ploskvah (Borovec in Gorica), za dob pa smo ugotovili kasnejše pojavljanje EGS le na ploskvi Murska Šuma. Značilna je velika variabilnost dolžine vegetacijskega obdobja (LGS) za bukev in dob po letih. Daljšanje LGS za bukev je statistično značilno za tri ploskve (Fondek, Borovec in Gorica), za dob pa spremembe LGS v opazovanem obdobju niso bile statistično značilne.

Title:Phenological phases of trees on the intensive forest monitoring plots in Slovenia
Abstract:Study of developmental stages of forest trees in a long time series is of increasing importance for determination of interdependence between meteorological variables and the associated biological responses. In our study we analyzed the needle appearance and leaf unfolding of conifers and deciduous trees and the autumn colouring for broad-leaved tree species. We considered the phenological phases for oak (Quercus robur L.) in research plots Krakovski gozd and Murska šuma, beech (Fagus sylvatica L.) in research plots Lontovž, Temenjak, Borovec, Fondek, Gorica; spruce (Picea abies (L.) Karst.) in research plots Kladje and Krucmanove Konte; Scotch pine (Pinus sylvestris L.) in the research plot Brdo, black pine (Pinus nigra Arnold) in the research plot Gropajski bori. On average, the needle appearance (BGS) of spruce started on the 166th Julian day. BGS of Scotch pine started on the 128th Julian Day, BGS of black pine on the 149th Julian day, respectively. The leaf unfolding (BGS) for beech started, on average, on the 128th Julian day and BGS for oak on the 117th Julian day, respectively. The autumn colouring(EGS) for beech, on average, started on the 297th Julian day, for oak on the 308th Julian day. It was assessed that BGS possibly commenced earlier for spruce, Scotch pine and black pine in all research plots during the 2004 to 2011 period. However, earlier BGS for beech and oak was noticed only in limited number of pots. Later EGS for beech could be confirmed in only two plots (Borovec in Gorica), whereas changes in EGS for oak were later only in plot Murska Šuma. There was a large variability of LGS for beech and oak over the years. Prolonged growing season (LGS) of beech was statistically significant for 3 plots (Fondek, Borovec in Gorica) during the 2004 to 2011 period. For oak prolonged LGS was not statistically significant during the observation period.
