Opis:
Colletotrichum coccodes (Wallr.) Hughes has been recognized as one of casual agents of anthracnose roots pepper in south-eastern Poland. During 2007–2012 the species was isolated from roots of sweet pepper (Capsicum annuum L.) cultivated in the field. The purpose of the study was morphological characterization and biotic activity of C. coccodes isolates. Five randomly chosen isolates from fungus population and one reference isolate obtained from Bank of Plant Pathogens and Investigation of their Biodiversity of IPP-NRI in Poznan in Poland were studied. The character of culture like growth rate, the colour of averse and reverse and the formation of morphological structures of the fungus such as acervuli, conidia, sclerotia were studied. Ultrastructural observations of morphological structures were made using light and scanning electron microscopy. Biotic activity of C. coccodes was conducted using the method of biotic series on PDA. Seven species of test fungi were used in the study: Alternaria alternata, Aureobasidium pullulans, Gibberella avenacea, G. intricans, Fusarium oxysporum, Penicillium aurantiogriseum, Trichoderma harzianum. The biotic activity test showed that C. coccodes is a weak competitor, and its development in the rhizosphere of sweet pepper may be limited by numerous antagonists.

Opis:
The aim of study was to investigate the effect of two mycorrhizal fungus species Claroideoglomus etunicatum and Rhizophagus intraradices on the uptake of macronutrients and on the growth and yield of tomato hybrid plants cultivated in an ecological system. The experiment was carried out at an ecological farm in Grądy in the Lublin province of Poland, for three years (2015-2017). The experimental treatments included plants inoculated with Claroideoglomus etunicatum, Rhizophagus intraradices and plants without mycorrhizal inoculation used as a control. The mycorrhization of tomato roots with Claroideoglomus etunicatum and Rhizophagus intraradices resulted in an improved uptake of Ca and K through the plants. The length of the tomato roots, especially for the cultivars treated with Claroideoglomus etunicatum, were statistically longer than those of the control. Tomato roots inoculation with both of the studied mycorrhizal fungus strains significantly influenced the number of tomato leaves and improved the health status of the plant. The yield of tomato was not significantly affected by mycorrhization but Claroideoglomus etunicatum, to a greater extent than Rhizophagus intraradices reduced the yield of diseased fruit compared to the control. Among the studied mycorrhizal fungus species, better results were obtained with the application of Claroideoglomus etunicatum as compared with Rhizophagus intraradices for all examined features. Mycorrhizal inoculation contributed to the better growth of the plants, it improved their health and may be beneficially applied in the ecological production of tomatoes.

Opis:
Three-year studies (2014–2016) were conducted in Lublin in the south-east Poland. The objects of research were the plants of ten canna cultivars: ‘Aida’, ‘America’, ‘Botanica’, ‘Cherry Red’, ‘La Boheme’, ‘Lucifer’, ‘Picasso’, ‘Robert Kemp’, ‘President’ and ‘Wyoming’. Observations were carried out each year in October. Plants with symptoms of stem and root rot, leaves yellowing and wilt were noticed on the investigated plantations. The plants were studied with regard to photosynthetic activity and also by disease index for all cultivars and statistical analysis was carried out upon them. The effect of disease index on photosynthetic intensity and transpiration was determined after the calculation of Pearson’s correlation coefficient. Infected plants were collected for mycological analysis. The results of mycological analysis showed that canna plants were colonized by Fusarium spp., Sclerotinia spp. and Alternaria spp. Alternaria alternata, Fusarium oxysporum, Fusarium avenaceum and Sclerotinia sclerotiorum predominated among pathogenic species. The best health status and the lowest number of colonies were noticed for plants of cv. ‘Botanica’. The infection of canna leaves by pathogenic fungi has negatively affected the intensity of photosynthesis, transpiration, stomatal conductance and sub-stomatal CO2 concentration and it was largely related to the degree of infestation of specified varieties of canna. The photosynthesis process was limited especially in ‘La Boheme’, ‘Picasso’, ‘Cherry Red’ and ‘President’ cultivars, which were infected most frequently by pathogenic fungi. It was confirmed by negative Pearson’s coefficient.
