20.500.12556/DiRROS-13729 Spremljanje koncentracije askospor glive Eutypella parasitica Monitoring the concentration of Eutypella parasitica ascospores Gliva Eutypella parasitica izvira iz Severne Amerike in povzroča bolezen, imenovano javorov rak. V Sloveniji so jo prvič našli leta 2005, zdaj je razširjena po vsej državi, izkoreninjenje bolezni ni več mogoče. Da bi preprečili nadaljnje širjenje bolezni in zmanjšali število novih okužb, je treba okužena drevesa posekati. Pri tem velja navodilo, da okuženi del debla izrežemo vsaj 50 cm nad rano in pod njo, izrezani del pa nato na mestu sežgemo ali pa položimo na gozdna tla tako, da je rakava rana usmerjena proti tlom. Učinkovitost slednjega ukrepa smo želeli preverjati s spremljanjem koncentracij askospor glive E. parasitica v zraku, pred izvedenim ukrepom in po njem. Spremljanje ni bilo uspešno, tako da učinkovitosti ukrepa ne moremo potrditi. V prispevku predstavljamo metode spremljanja in razpravo o morebitnih razlogih za neuspešno lovljenje askospor glive E. parasitica. Fungus Eutypella parasitica originates in North America and causes a disease called Eutypella canker of maple. In Slovenia, it was found for the first time in the year 2005; now it is spread in the whole country and the disease cannot be rooted out anymore. To prevent further spread of the disease and reduce the number of new infections, the infected trees must be cut down. Thereby, the valid instruction requires the infected part of the trunk should be cut out at least 50 cm above and under the wound and that the cut-out part should be burned on the spot or laid on the forest soil in such a way that the canker wound is facing the soil. We wanted to test the effectiveness of the latter measure by monitoring the ascospores of the E. parasitica fungus concentration in the air before the performed measure and after it. Monitoring was not successful; thus, we cannot confirm the effectiveness of this measure. In the article, we present our monitoring methods and discussion about possible reasons for unsuccessful catching of the E. parasitica fungus ascospores. javorov rak Eutypella parasitica monitoring volumetrični vzorčevalnik Slovenija Eutypella canker of maple Eutypella parasitica monitoring volumetric sampler Slovenia true false true Slovenski jezik Ni določen Delo ni kategorizirano 2021-03-08 10:48:00 2021-03-08 10:57:40 2022-08-19 03:36:20 0000-00-00 00:00:00 2021 0 2021 str. 21-27 št. 1 Letn. 79 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*17 0017-2723 54049283 3736834 GV_1_2021_HauptmanT.pdf GV_1_2021_HauptmanT.pdf 1 35AC64AB95BCF47810FDE8345575DEA4 e7e136be7b80936de3675f0840e87d5bd8dafa01ef5df2c2f84616676f53c883 738c6be9-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=16780 Zveza gozdarskih društev Slovenije Gozdarski vestnik 0 0 0
