tatra mts. - Opis:
- Swedish whitebeam (Sorbus intermedia (Ehrh.) Pers.) is a species with a very limited range. It occurs only in southern Scandinavia and along the Baltic coast, without the Gulf of Finland. Its southernmost natural localities are situated in northern Poland. They are few in number, grouped in two regions: near Kołobrzeg and the Gulf of Gdańsk. Currently, only three of them survive: vicinity of Sarbinowo as well as Kępa Redłowska and Przylądek Rożewski. In the Podtatrze region, S. intermedia has long been planted along roads, on green areas, in gardens and parks, among others in Zakopane. In the Tatras it did not appear, so it is a foreign species for this region. Currently, in the Tatra National Park there are several hundred fruiting specimens of this species growing. Most of them are part of a forty−year−old stand planted on the back of the Grzybowiec ridge. The aim of this research was to recognise the health status of S. intermedia. Phytopathological research was conducted in 2018 in the Tatra National Park. Leaves that were subject to analysis were decontaminated in 1% surfactant solution of sodium hypochlorite. Their fragments of about 0.5 cm were placed on Petri plates with PDA (Potato Dextrose Agar). The growing fungal colonies were consequently re−planted onto PDA slants for further culturing and taxonomic identification. The pathogens were identified basing on morphological features and with molecular tools. All S. intermedia in the Tatra National Park showed disease symptoms. Infected S. intermedia leaves were colonized by A. alternata, which fraction amounted to over 40%. The following dominant was B. exigua with over 30% share. F. avenaceum (close to 10%) and E. nigrum and D. macrostoma were also found. The S. intermedia population growing in the Tatra National Park is characterized by a poor condition, which may in the future affect the population of this plant in the Tatra Mts.
