Abstract
Cilj diplomske naloge je bil ugotoviti prisotnost javorovega raka (Eutypella parasitica) na območju Bohorja. V raziskavo so bili vključeni gorski javor (Acer pseudoplatanus), ostrolistni javor (Acer platanoides) in maklen (Acer campestre). Raziskava je potekala na šestih ploskvah, tj. dve ploskvi na vrsto javorja. Najprej smo določili lokacije ploskev glede na lesno zalogo posamezne vrste javorja v sestoju. Na vsaki ploskvi smo pregledali 100 dreves. Vsakemu javorju smo izmerili prsni premer. Javorje, ki so kazali znake okužbe z glivo E. parasitica, smo še dodatno pregledali. Zabeležili smo višino središča rakave rane na deblu, vertikalno dolžino raka, ter s pomočjo GPS aparata določili koordinate in te točke izrisali na karti. Z drevesa z znaki okužbe E. parasitica smo odvzeli vzorec skorje iz rakave tvorbe. Vzorce smo mikroskopirali in s tem še dodatno preverili ali gre za javorov rak. Pozitivne vzorce smo shranili v Mikoteko in herbarij Gozdarskega inštituta Slovenije. Našli smo 5 primerkov javorovega raka na maklenu. Intenziteta pojava javorovega raka je bila na vseh treh vrstah javorjev 0,83 %, na eni ploskvi z maklenom pa je bila 3%.

Title:Eutypella canker of maple (Eutypella parasitica) in selected forest stands in the Bohor area
Abstract:
The objective of this diploma thesis was to determine the presence of Eutypella canker of maple (Eutypella parasitica) on maples in the area of Bohor. The research covered sycamore maple (Acer pseudoplatanus), Norway maple (Acer platanoides) and field maple (Acer campestre). The research was conducted on six plots, i.e. two plots per maple species. First, the location of plots by growing stock of individual maple species in the stand was determined. On each plot 100 trees were examined for the disease. The diameter at breast height of all maples was measured. Maples showing signs of E. parasitica infection were further examined. We recorded the height of the canker centre on the trunk and the vertical length of the canker, determined the coordinates with the help of GPS and marked them on the map. Samples of the bark from the canker were taken from the trees with signs of E. parasitica infection. These samples were examined under microscope and thus further checked for the presence of Eutypella canker of maple. Positive samples were stored in Mycotheca and Herbarium of Slovenian Forestry Institute. Five instances of Eutypella canker of maple were found on field maple. The intensity of the occurrence of Eutypella canker on all three species of maple was 0.83 %, and on the plot with field maple, it was 3%.
