Choroby grzybowe występujące na arcydzięglu litworze (Archangelica officinalis Hoffm.) na terenie Małopolski [Occurrence of fungal diseases on angelica (Archangelica officinalis Hoffm.) in the region of Małopolska]

Abstract

The field experiment on angelica (Archangelica officinalis Hoffm.) was carried out in the years 2001-2002 at the plantations situated in Małopolska (Mydlniki near Kraków and Królówka near Bochnia). The results of two years' investigations pointed out, that angelica plants during vegetation were infested by many pathogens. The most often noticed on the plants were angelica rust (Puccinia anglicae), powdery mildew (Erysiphe umbelliferarum) and Cercospora leaf spot (Cercospora sp.). Moreover, many various types of disease symptoms, which were described and made a diagnosis. There were mainly spots on leaves and steams, from which there were isolated most often fungi from Alternaria genus. The investigations on the salubrity of the seed material (angelica fruits) coming from different sources showed that fungi from genus Alternaria were likely to transfer by seeds and caused disease symptoms on plants during vegetation. Fungi from genus Alternaria were most often isolated from angelica fruits. Saprotrophic fungi (Epicoccum purpurascens, Penicillium spp., Mucor hiemalis) were also often isolated from angelica fruits. Disinfection on fruits reduced number of isolated fungi and bacteria.
