20.500.12556/DiRROS-20417 Morfološka variabilnost črnike (Quercus ilex L.) v Sloveniji Morphological variability of holm oak (Quercus ilex L.) in Slovenia V članku je predstavljena črnika (Quercus ilex L.), ena glavnih drevesnih vrst evmediteranske flore na območju Slovenije, kjer raste na razpršenih nahajališčih na severni meji svojega naravnega areala. Glavni namen raziskave je bil preučiti morfološko variabilnost njenih listov. V raziskavo je bilo vključenih sedem naravnih populacij črnike v Sloveniji. Morfometrijska analiza je pokazala veliko variabilnost listov in značilne razlike med populacijami, ki smo jih potrdili pri skoraj vseh preučevanih morfoloških znakih. Na podlagi ugotovljenih morfoloških razlik lahko slovenske populacije razdelimo v tri geografskomorfološke skupine: i) populacije na Goriškem (Sabotin, Sv. Gora in Lijak), ii) Nanos - Osp in iii) populaciji v dolini reke Dragonje. Morfološka variabilnost kot odsev genetske variabilnosti je posledica prilagoditve na lokalne okoljske razmere. Črnika v Sloveniji za zdaj ni ogrožena vrsta, vendar bi bilo pri morebitnih aktivnih varstvenih ukrepih za njeno ohranjanje smiselno čimbolj upoštevati ugotovljene tri geografsko-morfološke skupine. This article introduces the holm oak (Quercus ilex L.), one of the most important tree species of the Mediterranean flora in Slovenia. In Slovenia, it grows in scattered locations at the northern limit of its natural range. The main aim of the study was to investigate the morphological variability of its leaves. Seven natural populations of holm oak in Slovenia were included in the study. The morphometric analysis showed high leaf variability and significant differences between populations, which were confirmed for almost all morphological traits analysed. Based on the observed morphological differences, the Slovenian populations can be divided into three geographical-morphological groups: i) the populations in the Goriška region (Sabotin, Sv. Gora and Lijak), ii) those in the Nanos – Osp region and iii) those in the Dragonja river valley. Morphological variability, as an expression of genetic variability, is the result of adaptation to specific local environmental conditions. The holm oak is currently not a threatened species in Slovenia, but it would be advisable to consider the three identified geographical-morphological groups as much as possible in any active conservation measures. črnika Quercus ilex morfološka variabilnost Slovenija drevesni listi holm oak Quercus ilex morphological variability Slovenia true false true Slovenski jezik Angleški jezik Neznano 2024-09-12 11:32:53 2024-09-12 11:32:54 2024-09-13 03:35:55 0000-00-00 00:00:00 2024 0 0 str. 1-10 Vol. 134 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 630*16+630*17(497.4)(045)=163.6 2335-3112 10.20315/ASetL.134.1 207275779 RAZ_Jez_Martin_2024.pdf RAZ_Jez_Martin_2024.pdf 1 A0846B072E5D0E8DE45A1469B4A89F1C c219372963f70ee38100e786eb43c81627d3ceaed6542c24d8e6b4675c482a8c a89159d1-70d9-11ef-9d3a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28733 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
