20.500.12556/DiRROS-7733 Osmotic component of water potential and stress adaption of adult Pedunculate oaks (Quercus robur L.) in stands with different tree density Osmotska komponenta vodnega potenciala in prilagoditev odraslih dobovih sestojev (Quercus robur L.) na sušni stres z različno sestojno gostoto Pressure volume curves were applied to define differences in stress adaptation between two managed forest complexes and virgin forest remnant; in Murska šuma, Krakovo forest and Krakovo old growth forest. Species response between adult stands after stronger thinning and comparable stand without any silvicultural measures within same forest complex was compared in two consecutive years, 2003 and 2004. Significant differences in osmotic potential (full turgor) component for plots in Murska šuma in 2003 as well as in Krakovo forest between managed forest and old growth-forest were confirmed. In all cases, values became more negative, indicating slight capability of oaks to adapt with increasing drought stress. Reaction/stress adaptation of forests after thinning indicated well adapted mechanism to address drought stress in spite of the age. We may connect such improved drought response with increased individual space for growth and lower stand density. Za primerjavo in opredelitev razlik stresnega prilagajanja na sušo odraslih dobovih sestojev smo uporabili P/V-krivulje; primerjali smo odzive gospodarskega gozda v Murski šumi, v Krakovskem gozdu in pragozdnega rezervata Krakovo kot tudi gospodarska sestoja z različno drevesno gostoto (redčen sestoj, neredčen) v poletnih mesecih 2003 in 2004. Potrdili smo značilne razlike v osmotski komponenti vodnega potenciala pri polnem turgorju med ploskvama Murske šume in Krakovskega gozda. Na vseh ploskvah je bilo opaziti povečevanje osmotske komponente z naraščanjem sušnega stresa. Sestoj po redčenju / uvajanju v obnovo je pokazal dobro oblikovan mehanizem in prilagajanje kljub starosti, najverjetneje zaradi sproščene konkurence in povečanega rastnega prostora. osmotska komponenta vodni potencial P/V krivulje dob Quercus robur L. sušni stres prilagoditve nižinski gozdovi true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-12 09:19:14 2017-07-12 09:19:14 2022-08-16 09:24:16 0000-00-00 00:00:00 2010 0 0 str. 33-38 Vol. 92 2010 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*1 0351-3114 URN:NBN:SI:doc-TWSNZPJU 3026854 6206978 RAZ_Cater_Matjaz_i2010.pdf RAZ_Cater_Matjaz_i2010.pdf 1 F08F56F362DB2160D1B8C59E7A9B4451 1b910498ec73fcdcefe32c9b0e6d5c108414be907d12062a5acd982f315730ad 262e55df-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/0511f18e-0f5b-4c47-ab36-879a9ce9f540 https://dirros.openscience.si/Dokument.php?lang=slv&id=9598 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
