20.500.12556/DiRROS-14285 Climatic regulation of leaf and cambial phenology in Quercus pubescens : their interlinkage and impact on xylem and phloem conduits Increased frequency and severity of stressful events affects the growth patterns and functioning of trees which adjust their phenology to given conditions. Here, we analysed environmental effects (temperature, precipitation, VPD and SWC) on the timing of leaf phenology, seasonal stem radial growth patterns, and xylem and phloem anatomy of Quercus pubescens in the sub-Mediterranean in the period 2014%2019, when various adverse weather events occurred, i.e. spring drought in 2015, summer fire in 2016 and summer drought in 2017. Results showed that the timings of leaf and cambium phenology do not occur simultaneously in Q. pubescens, reflecting different environmental and internal constraints. Although year-to-year variability in the timings of leaf and cambial phenology exists, their chronological sequence is fairly fixed. Different effects of weather conditions on different stages of leaf development in spring were observed. Common climatic drivers (i.e., negative effect of hot and dry summers and a positive effect of increasing moisture availability in winter and summer) were found to affect the widths of xylem and phloem increments with more pronounced effect on late formed parts. A legacy effect of the timing of leaf and cambial phenology of the previous growing season on the timing of phenology of the following spring was confirmed. Rarely available phloem data permitted a comprehensive insight into the interlinkage of the timing of cambium and leaf phenology and adjustment strategies of vascular tissues in Mediterranean pubescent oak to various environmental constraints, including frequent extreme events (drought, fire). Our results suggest that predicted changes in autumn/winter and spring climatic conditions for this area could affect the timings of leaf and stem cambial phenology of Q. pubescens in the coming years, which would affect stem xylem and phloem structure and hydraulic properties, and ultimately its performance. pubescent oak leaf development radial growth initial earlywood vessel sieve tube anatomy cambial cell production extreme weather events puhasti hrast razvoj listov debelinska rast začetne traheje ranega lesa sitaste cevi anatomija kambijska proizvodnja celic ekstremni vremenski pojavi true false true Angleški jezik Ni določen Neznano 2021-09-06 13:35:11 2021-09-06 13:35:13 2022-08-20 03:34:42 0000-00-00 00:00:00 2022 0 0 Soavtorji: Jernej Jevšenak, Polona Hafner, Peter Prislan, Mitja Ferlan, Martina Lavrič, Dominik Vodnik, Klemen Eler; str. 1-13 Vol. 802 2022 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2023-09-03 630*81 0048-9697 10.1016/j.scitotenv.2021.149968 75293699 RAZ_Gricar_Jozica_i2022.pdf RAZ_Gricar_Jozica_i2022.pdf 1 D55C1C125D949F14FE8BF9A654350BA8 e9d9cd5862e08657a4d63d9f201f732c1a32185466fa9113a9118f9830f8d237 ab63fc3e-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=17980 https://www.sciencedirect.com/science/article/pii/S0048969721050439?via%3Dihub 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=17979 Gozdarski inštitut Slovenije 0 0 0
