o:6800 WHITE WILLOW (Salix alba L.) VARIABILITY IN THE LANDSCAPES OF OUTSTANDING FEATURES “GREAT WAR ISLAND” BASED ON MORPHOLOGICAL TRAITS OF THE LEAVES: A BASIS FOR ASSESSMENT OF GENE POOL VARIJABILNOST BELE VRBE (Salix alba L.) NA PODRUČJU PIO „VELIKO RATNO OSTRVO” PREMA MORFOLOŠKIM SVOJSTVIMA LISTOVA: OSNOVA ZA PROCENU STANJA GENOFONDA en sr The gene pool assessment of woody species has multiple significance in biotechnology. This research paper studied the morphological traits of white willow leaves in the Landscapes of Outstanding Features (LOF) “Great War Island”. The variability of leaf length, width, area, and circumference, as well as the petiole length of the white willow tested trees were determined. Different parameters show varying degrees of variability. The trees were grouped into multiple clusters based on the average distance of the tested parameters. The results provide a realistic basis for evaluating the gene pool and show great potential for the conservation and production of white willow reproductive material adapted to the changed habitat conditions in Serbia. In this way, the condition of this specific area, as well as other coastal forests in Serbia, is improved. It is possible to improve protection measures against harmful organisms, primarily pathogens of white willow leaves, by applying these findings and reducing the occurrence of certain types of harmful bacteria and fungi, which are associated with decreased vitality and poor physiological condition of trees. The results obtained in the research will facilitate the management and preservation of the white willow gene pool in these unique Landscapes of Outstanding Features. Potreba za procenom stanja genofonda drvenastih vrsta ima višestruki značaj u biotehnologiji. Cilj ovog rada je istraživanje morfoloških karakteristika listova bele vrbe na području PIO Veliko ratno ostrvo. Utvrđena je varijabilnost u dužini, širini, površini i obimu listova, kao i dužini peteljke bele vrbe. Takođe, različiti parametri pokazuju nejednaku varijabilnost. Stabla su grupisana u više klastera na osnovu prosečne udaljenosti testiranih parametara. Dobijeni rezultati daju realnu osnovu za procenu genofonda i pokazuju da postoji veliki potencijal za konzervaciju i proizvodnju reproduktivnog materijala bele vrbe prilagođenog izmenjenim stanišnim uslovima u Srbiji. Na taj način, postiže se unapređenje stanja konkretnog ispitivanog područja ali i drugih priobalnih šuma u Srbiju. Primenom ovih rezultata, moguće je unaprediti mere zaštite protiv štetnih organizama, prvenstveno patogena listova bele vrbe. Takođe, smanjuje se pojava određenih vrsta štetnih bakterija i gljiva koje su povezane sa umanjenom vitalnosti i lošim fiziološkim stanjem stabala. Rezultati dobijeni u istraživanju će olakšati upravljaču gazdovanje i očuvanje genofonda bele vrbe u ovom jedinstvenom predelu izuzetnih odlika. white willow, variability assessment, gene pool, conservation. bela vrba, procena varijabilnosti, genofond, konzervacija 1552099 10.5937/SustFor2490017P 1552101 1821-1046 2025-01-08T14:46:59.954Z 44 yes 46 Vladan Popović 0000-0003-4326-3364 46 Aleksandar Lučić 0000-0002-4473-1791 46 Aleksandar Vemić 0000-0001-9195-8967 46 Sanja Jovanović 0000-0001-9468-2628 46 Ivona Kerkez-Janković 46 Mirjana Šijačić-Nikolić application/pdf 944434 https://unilib.phaidrabg.rs/o:6800 no yes 16 70 92000001 2024 71A07 Sustainable Forestry: Collection 89-90 17 30 Институт за шумарство, Београд, Србија 2024
