20.500.12556/RUL-122429 Inter-tree variability of autumn leaf phenology of European beech (Fagus sylvatica) on a site in Ljubljana, Slovenia Variabilnost jesenske listne fenologije med drevesi navadne bukve (Fagus sylvatica) na rastišču v Ljubljani Temporal variability of leaf senescence (autumn phenology) was observed in 2020 in 11 European beech (Fagus sylvatica) trees in Tivoli, Rožnik and Šišenski hrib Landscape Park in Ljubljana, Slovenia, previously this year observed also for spring phenology. General leaf colouring (LC) BBCH94 occurred, between 19 and 24 October 2020, with lower inter-individual variability than that of leaf unfolding (LU), BBCH11. The trees had active leaves (LC-LU) between 177 and 199 days. In only 3 trees total leaf fall (LF), BBCH97, occurred before 19 November 2020. LC of the tree included in the long-term monitoring program of the Slovenian Environment Agency ARSO occurred on 24 October 2020. This is 7 days later than 65-year average of the same tree/location and is ascribed to weather conditions. Investigation of tree tissues showed that the width of the last formed tree-ring in the wood varied between 0.39 and 9.61 mm and in phloem between 0.09 and 0.26 mm and that the tissues reflect health condition of the trees. V letu 2020 smo spremljali jesensko fenologijo listov 11 dreves evropske bukve (Fagus sylvatica) v Krajinskem parku Tivoli, Rožnik in Šišenski hrib v Ljubljani, Slovenija. Pri istih drevesih smo spomladi spremljali proces olistanja. Splošno obarvanje listov (LC), BBCH94, je nastopilo med 19. in 24. oktobrom 2020, v ožjem časovnem intervalu kot spomladansko olistanje (LU), BBCH11. Drevesa so imela aktivne liste (LC-LU) od 177 do 199 dni. Samo s 3 dreves je do 19. novembra 2020 odpadlo vse listje (LF), BBCH97. Pri drevesu, ki je vključeno v dolgoletni program spremljanja fenologije listov Agencije Republike Slovenije za okolje ARSO, je obarvanje listov nastopilo 24. oktobra 2020, kar je za 7 dni kasneje od 65-letnega povprečja za isto drevo / lokacijo. Raziskave drevesnih tkiv so pokazale, da je znašala širina zadnje branike v lesu med 0,39 in 9,61 mm in v floemu med 0,09 in 0,26 mm in da tkiva nakazujejo zdravstveno stanje dreves. leaf phenology autumn leaf colouring leaf fall wood formation wood formation inter-individual variability European beech (Fagus sylvatica) Slovenia fenologija jesen obarvanje listov odpad listov nastajanje lesa variabilnost med osebki bukev (Fagus sylvatica) Slovenija true false false Repozitorij Univerze v Ljubljani Angleški jezik Slovenski jezik Neznano 2020-12-10 13:13:51 2020-12-10 13:26:21 2026-02-20 13:32:07 0000-00-00 00:00:00 2020 0 Ljubljana 0 The supplement contains detailed photos of leaf senescence in European beech (Fagus sylvatica) (tree 30 in this study) which is as a plant number 221 included in the long-term monitoring of the Slovenian National Phenological Network of the Environmental Agency of the Republic of Slovenia (ARSO) within the Ministry of the Environment and Spatial Planning as a part of the International Phenological Gardens of Europe. 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*181.8:630*176.1 269171971 RAZ_Skrk_Nina_0.docx RAZ_Skrk_Nina_0.docx README 1 4F85734A3790DAC92DE2EB44D8DE5CCA 72dce37c98458eabc3204edb55736d82f70e4aebfdbe721e086af8ee16836cbc 1ac0dd24-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=137615 RAZ_Skrk_Nina_0.pdf RAZ_Skrk_Nina_0.pdf 1 9CEB3AF608BE95D3CABB36DE013A1B05 ba5254829ed20093b65690305b9fd46eaa95fcd8683ea3160cb0538a00ce187c 1aaddd9f-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=137614 Biotehniška fakulteta 0 0 0
