Glavni cilj diplomske naloge je bil preveriti razširjenost javorovega raka (Eutypella parasitica) v gozdovih v okolici gradu Jable (KE Domžale). Razširjenost bolezni smo ugotavljali z dvema različnima metodama, in sicer z metodo popisa na stojiščih sistematične vzorčne mreže 50 × 50 m in z metodo popisa ob poteh in prometnicah. Pri popisu dreves smo bili posebej pozorni na znake okužbe z javorovim rakom: rakave rane na deblih, črne peritecije na okuženi skorji in bele do krem micelijske pahljačice pod okuženo skorjo. Z omenjenima metodama smo odkrili 3 različne javore, okužene z glivo E. parasitica, slučajno pa smo pri našem delu odkrili še dva druga javorova raka. Metoda popisa javorov ob gozdnih poteh in prometnicah je bila lažje izvedljiva in manj zamudna. Z omenjeno metodo smo našli tri javore, okužene z glivo E. parasitica, z metodo popisa na točkah sistematične mreže pa le enega. Ti rezultati sicer nakazujejo, da bi lahko bila metoda popisa ob poteh in prometnicah iz vidika iskanja javorovih rakov tudi bolj učinkovita, vendar je potrebno dodati, da je vzorec popisanih dreves oziroma vzorec okuženih dreves premajhen, da bi lahko delali zanesljive zaključke. Delež javorov okuženih z javorovim rakom je bil v naši raziskavi manjši od 3 %, predvidevamo pa, da je zaradi asimptomatičnih okužb v resnici ta delež večji.

Naslov:Incidence of Eutypella cranker (Eutypella parasitica) in the vicinity of Jable castle
Izvleček:
The main goal of the diploma thesis was to examine the prevalence of maple cancer (Eutypella parasitica) in the forests in the vicinity of Jable castle (Domžale regional unit). The prevalence of the disease was examined by two different methods, namely the inventory method at points of systematic grid of 50 × 50 m and the inventory method along forest paths and roads. During the inventory, special attention was paid to the signs of maple cancer infection: cancer wounds on the trunks, black perithecia on the infected bark, and white to cream mycelial fans under the infected bark. With the mentioned methods, 3 different maples infected with the fungus E. parasitica were discovered. Two additional maple cancers were discovered during our field work by chance. The inventory method along forest paths and roads was easier to implement and less time consuming. With this method, three maples infected with the fungus E. parasitica were found, and with the inventory method on a systematic grid, only one. Although these results suggest that the inventory method along paths and roads could be more efficient as a maple cancer monitoring method, it should be added that the sample of surveyed trees or the sample of infected trees is much too small to draw reliable conclusions. The proportion of maples infected with E. parasitica was less than 3% in our study, but we assume that due to asymptomatic infections, this proportion is actually higher.
