FUNGI ASSOCIATED WITH PLANTS OF CALAMUS (ACORUS CALAMUS)

摘要

The health status of calamus (Acorus calamus) in four growing seasons (2006 and 2008-2010) in 20 garden ponds was defined. Fungi inhabiting calamus phyllosphere, causing various spots and necrosis, which resulted in reduction of aesthetic values weredetermined. Out of 28 species of parasitic fungi, isolated from calamus leaves and stems, those constantly associated with plants were: Alternaria alternata, Epicoccum purpurascens and Penicillium yerrucosum var. cyclopium. From the infected tissues mostfrequently isolated were: A. alternata, Paecilomyces farinosus, E. purpurascens, Botrytis cinerea and Aspergillus niger. Ascochyta acori, a monofagous species rarely quoted in Poland, was found in spots on calamus leaves.
