Heavily urbanised areas are not a favourable habitat for plant growth and development. On the other hand, urbanised areas can be a favourable habitat for harmful fauna. Tin our study, those trees growing along the roadside were more heavily infested by pests than trees growing in parks. Three orders of insects, mites and lugs were identified on the Norway maple. The dominant insect species was Periphyllus...
Green moulds caused by Trichoderma result in considerable losses in the growing of several species of cultivated and medicinal mushrooms. Pholiota nameko is a mushroom species well-known in many Asian countries. The aim of the studies was to determine the effect of substrate infestation with Trichoderma isolates on yielding of P. nameko. The experiment was conducted on four strains of P. nameko, i...
The influence of substrate infestation with Trichoderma pleurotum and T. pleuroticola isolates on yielding of two commercial strains of Pleurotus ostreatus was investigated. The examined P. ostreatus strains growing on substrates infested with Trichoderma isolates showed a considerable yield decline. T. pleuroticola isolates were found to exert a greater unfavorable impact on P. ostreatus yields than...
The occurrence of fungi from the genus Trichoderma constitutes a serious problem in the culture of Agaricus bisporus leading to considerable losses. The aim of the investigations was to compare mutual interaction between some isolates of Trichoderma sp. and single-spore heterokaryotic cultures of A. bisporus on agar media and in cultivation conditions. The first stage of the study comprised assessment...
Functional food market develops dynamically all over the world although in Poland consumers knowledge in this area is insufficient. An importance of functional food mainly arises from contained bioactive substances. Funcional food includes also mushrooms which contain polisaccharides, especially E-glucans. These compounds differ in structure, water solubility, molecule size and molecular mass which...
The impact of different isolates of three species of the Trichoderma genus on the development of wild strains of Coprinus comatus mycelium was investigated. Nine strains of C. comatus obtained from natural sites and one cultivated strain were used in the trail. The following Trichoderma isolates were used: T. aggressivum f. europaeum, T. longibrachiatum and T. atroviride. It was found that isolates...
The impact of infestation with Trichoderma aggressivum f. europeanum and Trichoderma longibrachiatum isolates on the yielding of three wild strains and one cultivated strain of Coprinus comatus was investigated. A significant yield reduction of C. comatus on substrates infested with the examined Trichoderma isolates was determined. The recorded percentage yield reduction was significantly higher in...
W latach 2007-2010 w Katedrze Fitopatologii Uniwersytetu Przyrodniczego w Poznaniu przeprowadzono badania dotyczące kumulacji kadmu i ołowiu w wybranych gatunkach ozdobnych roślin iglastych (Chamaecyparis lawsoniana, Juni- perus X pfiizeriana, Thuja occidentalis). Kadm i ołów wprowadzono w następujących dawkach: Cd - 5 i 25 mg·dm³; Pb - 50 i 150 mg·dm³. W trakcie trwania doświadczeń dokonywano pomiarów...
The effect of infections with Trichoderma aggressivum f. europaeum on the yielding of seven wild and one commercial strain of Agaricus bisporus (Lange) Imbach. was investigated. Wild strains of the mushroom were derived from natural habitats of Poland. The cultivation substrate was inoculated with two different isolates of T. aggressivum f. europaeum Th2. It was found that infections of the substrate...
Investigations were conducted in the years 2007–2008 at the Department of Phytopathology, Poznań University of Life Sciences. The study presents the evaluation of efficacy of three selected preparations: Biochikol 020 PC (chitosan), Mirage 450 EC (prochloraz) and Topsin M 500 SC (thiophanate-methyl) recommended for protection of coniferous ornamental plants against fungal pathogens. In the experiments...
