This work is a continuation of research on Diaporthe genus isolates obtained in 2010−2012 from fruit trees in Poland, which on the basis of previously conducted molecular tests, have been identified as one species belonging to the Diaporthe eres species complex. The aim of this study was to determine the morphology and pathogenic abilities of tested Diaporthe eres isolates. The experiment included...
The objective of undertaken studies was evaluation in vitro conditions efficiency of eight fungicides from different chemical groups and three preparations of natural origin i.e. Biosept Active, Beta-chikol and Bioczos towards isolate M 365 Boeremia strasseri, obtained from peppermint rhizomes showing symptoms of black rot. Test were performed by poisoning the culture media. The percentage of inhibition...
The purpose of the study was to determine which fungal species colonize the shoots of apple, pear, cherry, plum, apricot and peach in south-eastern Poland and whether Diaporthe (Phomopsis) isolates there are among them. The study was conducted in 2010–2012 and the plant material was collected from five orchards. In three of these chemical controls were carried out, while there was no protection applied...
The paper concerns the fungus Phoma complanata, isolated for the first time in Poland, from the roots and umbels of angelica (Archangelica officinalis) in 2009. The morphology of fungal isolates was tested on standard culture media. Moreover, the sequence analysis of ITS regions was conducted. Morphological similarity of P. complanata Polish isolates to the reference isolate obtained from CBS culture...
Asphondylia spp. (Diptera: Cecidomyiidae) are known for inducing gall formation on many diverse plants in both wild and agricultural contexts. The species Asphondylia serpylli is herewith reported for the first time on thyme (Thymus vulgaris) cropped in Poland. The associated fungus has been identified as Botryosphaeria dothidea, representing its first record from cecidomyiid galls on a species of...
During 2012–2014 in southeastern Poland the species Colletotrichum fuscum was isolated from the leaves of oregano (Origanum vulgare L.) showing the symptoms of necrotic, concentrically zoned spots with a lighter center and a slightly raised edge. Morphology of nine randomly chosen isolates from the fungus population and reference isolate CBS obtained from CBS-KNAW Fungal Biodiversity Centre were studied...
Studies on diversity of fungi colonizing and damaging different plant parts of oregano (Origanum vulgare L.) were carried out in 2012–2014 on production plantations grouped in south-eastern Poland. Fungi were isolated from superficially disinfected roots, stems and leaves using mineral medium. Fungi from Fusarium spp., Boeremia exigua var. exigua and Rhizoctonia solani were obtained from the roots...
Pectinases have multiple nature and various forms which are necessary for hydrolysis of pectin in natural processes. The pectinolytic activity of three isolates of the pathogenic fungus Boeremia strasseri was demonstrated. The pectinases production was studied using a liquid Mandels-Weber medium, containing 1.0% citric pectin as a carbon source. Optimum pH and temperature for pectinases activity were...
The seeds of forest trees usually transfer numerous fungi species, including pathogens, facultative parasites and saprotrophs. The aim of the present work was to determine qualitative and quantitative composition of fungi inhabiting the seeds of 10 trees species i.e.: birch (Betula pendula Roth.), beech (Fagus sylvatica L.), red oak (Quercus rubra L.), common oak (Quercus robur L.), sycamore maple...
The plants of angelica Archangelica officinalis may be colonized by various species of fungi including Phoma species. The paper concerns the fungus Phoma complanata, isolated from above-ground and underground parts of angelica in 2009–2011. Pathogenicity tests according to Koch’s postulates were carried out on angelica plants using various methods of inoculation. Observations of the infection process...
Pathogenicity and ultrastructural investigation of the ribwort leaves inoculated with Phyllosticta plantaginis conidia was undertaken using scanning electron microscopy to examine the host-parasite relationship. Pathogenicity experiments demonstrated that all tested P. plantaginis isolates had infected leaves of ribwort. Of all inoculation methods, direct placement of colonized agar plugs on damaged...
Studies on diversity of fungi colonizing and damaging selected plant parts of ribwort (Plantago lanceolata L.) were carried out in 2009–2011 on plantations grouped in south-eastern Poland. Fungi were isolated from superficially disinfected roots, collar roots and leaves by means of a mineral medium. Fungi from Fusarium spp., Boeremia exigua var. exigua comb. nov. and Rhizoctonia solani were obtained...
Celem przedstawionych badań było porównanie zwilżalności oraz swobodnej energii powierzchniowej tkanki kostnej i chrzęstnej pochodzenia zwierzęcego oraz wybranych biomateriałów, wykorzystując model Owens’a-Wendt’a. W badaniach przeprowadzonych w Zakładzie Mechaniki Doświadczalnej i Biomechaniki Politechniki Krakowskiej wyznaczono również kąt zwilżania tych materiałów.
Pathogenicity and ultrastructural investigation of the inoculation of peppermint stems and rhizomes with Phoma strasseri conidia was undertaken using scanning and transmission electron microscopy to examine the host-parasite relationship. Pathogenicity experiments demonstrated that all tested P. strasseri isolates had infected the stems and rhizomes of peppermint. Of all inoculation methods, direct...
