OCCURRENCE OF WHITE POCKET HEARTWOOD ROT SYMPTOMS HEARTWOOD OF SCOTS PINE TREES IN THE OBORNIKI FOREST DISTRICT
Abstract
This study assessed the threat posed by the fungus Porodaedalea pini in selected residual Scots pine (Pinus sylvestris) stands in the Oborniki Forest District. Sixteen research plots were surveyed, with a total of 535 trees inventoried. A total of 22 fruiting bodies and 11 cavities were observed, while disease symptoms were found in only 14 trees (2.6%). The low number of infected trees indicates good phytosanitary condition of the surveyed stands; however, the affected trees exhibited high levels of defoliation.
Keywords: Phellinus pini, Scots pine, residual trees, white pocket rot, defoliation, red ring rot
