20.500.12556/DiRROS-7788 Influence of meteorological conditions and crown defoliation on tree phenology in intensive forest monitoring plots in Slovenia Vpliv vremenskih spremenljivk in osutosti krošenj na fenološke faze dreves na ploskvah intenzivnega monitoringa gozdnih ekosistemov v Sloveniji Data from the forest monitoring programme in Slovenia were used to assess the relationship between tree phenology, crown defoliation and meteorological conditions in Fagus sylvatica, Quercus robur and Picea abies forests in the 2004-2013 period. We hypothesized a species-specific response of first leaf unfolding, general leaf colouring, the length of the growing season to crown defoliation, air temperature, precipitation and soil water. In accordance with the hypothesis, we found a high sensitivity of first leaf unfolding to air temperature and precipitation for all species, exhibiting contrasting responses. We observed strong sensitivity of beech defoliation to precipitation and soil water conditions. Oak crown defoliation and next-year phenology were correlated, with higher crown defoliation contributing to earlier leaf unfolding, later autumn leaf colouring and longer growing season of oak in next year. Correlation between crown defoliation and phenology was found neither for beech nor spruce. V naši raziskavi smo na podlagi podatkov spremljanja stanja gozdnih ekosistemov v Sloveniji ugotavljali povezanost fenofaz dreves, osutosti krošenj dreves in vremenskih razmer v gozdovih bukve, doba in smreke v letih 2004-2013. Predpostavili smo, da je odziv fenofaz prvih listov in iglic, splošnega rumenenja listja in dolžine vegetacijskega obdobja na osutost krošenj, temperaturo zraka, padavine in vsebnost vode v tleh vrstno specifičen. Ugotovili smo veliko odzivnost nastopa fenofaze prvih listov in iglic na temperaturo zraka in padavine za vse obravnavane drevesne vrste, vendar so se odzivi razlikovali. Ugotovili smo tudi veliko odzivnost osutosti krošnje bukve na količino padavin in vsebnost vode v tleh. Osutost krošenj in fenofaze doba v sledečem letu so bile korelirane, pri čemer je večja osutost krošenj prispevala k zgodnejšemu nastopu fenofaze prvih listov, splošnega rumenenja listja in dolžine vegetacijskega obdobja za dob v sledečem letu. Nismo pa ugotovili povezanosti med osutostjo krošenj in fenofazami bukve ali smreke. monitoring gozni ekosistemi fenologija dreves osutost krošenj temperatura zraka padavine tla vsebnov vode v tleh Slovenija true false true Angleški jezik Angleški jezik Znanstveno delo 2017-07-12 09:19:30 2017-07-12 09:19:30 2022-08-16 09:28:54 0000-00-00 00:00:00 2014 0 0 Besedilo v angl.; str. 1-15 Vol. 105 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*18:630*53(497.4)(045)=111 2335-3112 URN:NBN:SI:doc-7UXGMVVO 10.20315/ASetL.105.1 4107942 266761216 RAZ_Vilhar_Ursa_i2014.pdf RAZ_Vilhar_Ursa_i2014.pdf 1 44A7C8554D5B8D543F890FB83825381B c87461cee3fb7b7d9811ae08e31476470ff16c4c148bbc25b686f4d16a199cf1 2a285945-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/536ba08d-dc07-490b-8d26-5ab3a9021309 https://dirros.openscience.si/Dokument.php?lang=slv&id=9653 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
