Studies on phytopathogenic and saprotrophic fungi in rush associations of Lake Glinno (NW Poland)

Abstract

During the vegetation seasons in years 2004-2005 the health state of rush plant species from Phragmition and Magnocaricion alliances around the Lake Glinno was investigated. From 13 plant species with disease symptoms 94 species of fungi and FLO were isolated. The highest mycological biodiversity was stated in Phragmitetum australis (24 species) and Thelypteridi-Phragmitetum (27 species) plant associations. The host species in which the biggest number of fungi and FLO species was observed were: Phragmites australis (37 species) and Carex acutiformis (25 species). The highest mycological similarity based on the Jaccard-Sörensen coefficient occurred between Caricetum acutiformis and Glycerietum maximae plant associations (50%) whereas the lowest value of the coefficient represented Glycerietum maximae and Phalaridetum arundinaceae associations (7%).
