20.500.12556/DiRROS-13792 Drought stress can induce the pathogenicity of Cryptostroma corticale, the causal agent of sooty bark disease of sycamore maple Reports of sooty bark disease of maples caused by the fungus Cryptostroma corticale have recently been emerging from across Europe. The aims of our study were to describe the first report of sooty bark disease in Slovenia, to determine the pathogenicity of C. corticale, to confirm the optimum temperature for the growth of the fungus, and to determine the mass loss of Acer pseudoplatanus wood inoculated by C. corticale. We confirmed the presence of C. corticale on A. pseudoplatanus via morphological and molecular analysis. The optimal growth of C. corticale was measured in vitro on potato dextrose agar and was determined to occur at 25 °C. Pathogenicity tests were performed on 30 saplings of A. pseudoplatanus under two treatments, humid and drought stress, and the fungus was pathogenic in both treatments. The mean length of bark lesions and wood discoloration of the drought-stressed saplings was significantly greater than that in the humid treatment. Re-isolations of C. corticale were successful from all inoculated saplings, and thus Koch%s postulates were confirmed. The mass loss of A. pseudoplatanus wood was determined by mini-block test in a period of 10 weeks and was observed as minimal. Based on the results, we conclude that C. corticale is a weak and opportunistic pathogen that most likely expresses itself intensively under hot and dry conditions. pathogenicity drought stress optimal growth climate change mass loss mini-block test wood rot opportunistic pathogen saprophyte endophyte patogenost stres zaradi suše optimalna rast sprememba podnebja izguba mase mini-blok test gniloba lesa oportunistični patogen saprofit endofit true false true Angleški jezik Ni določen Neznano 2021-03-23 08:27:13 2021-03-23 08:27:16 2022-08-19 03:36:45 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Opis vira z dne 22. 3. 2021; Abstract; 12 str. iss. 3 article 377 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*4 1999-4907 10.3390/f12030377 56641539 RAZ_Ogris_Nikica_i2021.pdf RAZ_Ogris_Nikica_i2021.pdf 1 1D057AACD554538B8E055DAB7A05D72B 42588136c406b110f5c1d2d78421354b0a908352ec0a30b33377ff6a441bc45c 77ecebcc-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=16886 https://www.mdpi.com/1999-4907/12/3/377 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=16885 Gozdarski inštitut Slovenije 0 0 0
