Glive povzročiteljice odmiranje in nekroz skorje zelenega bora v nasadih iglavcev Mlake v Beli krajini : diplomsko delo - visokošolski strokovni študij - 1. stopnja

V diplomski nalogi smo raziskovali zdravstveno stanje in bolezni zelenega bora (Pinus strobus) v nasadih iglavcev v Mlakah v Beli krajini. Namen naloge je bil določiti povzročitelje odmiranja borov in nekroz skorje na odmirajočih drevesih zelenega bora. V nasadih smo zato v letu 2015 večkrat nabrali vzorce obolelih rastlinskih delov, na Gozdarskem inštitutu Slovenije pa smo določevali povzročitelje bolezni. Vzorce smo shranili v zbirko živih kultur Laboratorija za varstvo gozdov na Gozdarskem inštitutu Slovenije. Ugotovili smo, da se na zelenem boru, ki odmira predvsem zaradi močne okuženosti korenin z glivo Phaeolus schweinitzii, pojavljata tudi dve vrsti gliv iz rodu Pezicula in sicer vrsta Pezicula eucrita ter Pezicula sp. Ena ali obe vrsti sta verjetno vpleteni v nastanek nekroz skorje odmirajočih zelenih borov v Mlakah v Beli krajini.

Izvleček

Health status and diseases found on Pinus strobus trees in conifer plantation Mlake in Bela Krajina were surveyed during this research. The purpose of the thesis was to determine fungi, causing necroses and drying of the bark on. P. strobus dying trees. In 2015 we collected samples of the diseased trees. Disease agents were determined in the Laboratory of Forest Protection at the Slovenian Forestry Institute. All fungal isolates, obtained during our research, were deposited in the Culture Collection of the Laboratory of Forest Protection at the Slovenian Forestry Institute. Based on our results and surveys, we conclude, that diebacks of P. strobus trees in Mlake are most likely a consequence of frequently present fungus Phaeolus schweinitzii. In addition, two fungal species from the genus Pezicula (P. eucrita and Pezicula sp.) were isolated from the diseased P. strobus trees. We believe that one or both species are also involved in the development of bark necroses of P. strobus in Mlake, Bela Krajina.
