Opis:: Mycorrhizal fungi influence the development and activity of communities of soil microorganisms. The purpose of this study was to estimate the effect of arbuscular mycorrhizal fungus Claroideoglomus etunicatum (W. N. Becker & Gerd.) C. Walker & Schüβler on the population structure of fungal colonies in the rhizosphere of tomatoes grown in a plastic tunnel. The field experiment was conducted from 2015 to 2017 at an ecological farm in Grądy, central eastern Poland. The object of study were the three tomato cultivars: ‘Antalya F 1 ’, ‘Esmira F 1 ’, and ‘Pelikan F 1 ’. Tomato seedlings were inoculated with C. etunicatum; spores were introduced about 5 cm deep in the rhizosphere of the studied plants (25–30 spores of C. etunicatum for each plant). Each year, mycological analysis of the tomato rhizosphere was conducted using Warcup’s method; structure of fungal communities of the tomato rhizosphere varied depending on the AMF applied. Saprotrophic fungi such as Trichoderma ssp., Mucor spp., and Penicillium spp. were often more isolated from the rhizosphere of plants inoculated with C. etunicatum than that of the control samples. It can be concluded that AMF directly impacted the development of fungal biodiversity in the tomato rhizosphere, particularly regarding the number of saprotrophs in the soil.

Opis:: Density and diversity of Fusarium species and other fungi associated with rhizosphere and rhizoplane of lentil and sesame plants at three different growth stages were investigated. Sixteen species of Fusarium were isolated from rhizosphere (13 species) and rhizoplane (11) of both plants studied. In lentil, 11 species were recorded from its rhizosphere (9 species) and rhizoplane (8). Fusarium species associated with lentil rhizoplane gave highest number of propagules at the first stage of plant growth while the ones of Fusarium associated with the rhizosphere produced the highest number at the second stage of growth. F. solani was the most common in the three growth stages. In addition, of two growth stages, F. culmorum and F. tricinctum were isolated from the rhizosphere while F. nygamai and F. verticillioides from the rhizoplane. The other species were recorded from only one growth stage of lentil plant. In sesame plants, rhizosphere yielded nine Fusarium species while rhizoplane gave only six from the three stages investigated. Stage I of sesame rhizosphere possessed the highest colony forming units of Fusarium. As the case for lentil, F. solani was the most common species in sesame rhizospere and rhizoplane. F. verticillioides and F. nygamai (in three different growth stages) followed by F. oxysporum and F. tricinctum (in two growth stages) were recorded using the dilution-plate and/or soil-plate methods from sesame rhizosphere soils. Rhizoplane Fusarium species of sesame plants were isolated at the three different growth stages with almost equal number of colony forming units. F. poae came after F. solani in its frequency since it was recovered from two growth stages. Several of the isolated species are well-known as pathogens to many cultivated plants. To the best of our knowledge, three species are recorded here for the first time in Egypt from the rhizosphere (F. acutatum), rhizoplane of sesame plants (F. longipes) and from rhizosphere of both lentil and sesame and rhizoplane of lentil (F. nygamai).

Opis:: A field experiment was performed during the years 2003-2005. An influence of EM (Effective Microorganisms) on the composition and number of fungi isolated from soil was found in the experiment. A total of 18111 fungal cultures were isolated from the roots of pea at flowering stage. The highest amount and the lowest diversity of fungi were obtained from rhizosphere of pea treated with pesticides (3257 colonies). The greatest diversity of fungi was found in the case of rhizosphere and rhizoplane, where EM was used in soil with the supplement of pesticides. The greatest amount and diversity of fungi were found from the plant roots of the control object. During the flowering stage, the fungi most frequently isolated from soil belonged to the genus Penicillium (40.78% of all isolates) and Fusarium (33.37% of all isolates).
Badania polowe prowadzono w latach 2003-2005. W badaniach stwierdzono wpływ szczepionki mikrobiologicznej EM 1 na zróżnicowanie składu gatunkowego i liczebność poznanych zbiorowisk grzybów. Ze środowiska glebowego w fazie kwitnienia grochu wyizolowano ogółem 18111 kolonii grzybów strzępkowych. Najliczniejsze zbiorowisko grzybów uzyskano z ryzosfery grochu kombinacji chronionej chemicznie (3257 kolonii), przy czym zbiorowiska te charakteryzowały się najmniejszą różnorodnością. Największą różnorodność gatunkową badanych zbiorowisk stwierdzono w przypadku ryzosfery i ryzoplany kombinacji, gdzie EM stosowano doglebowo w połączeniu z ochroną chemiczną. Największą różnorodność, a także liczebność grzybów wyizolowanych z korzeni roślin zanotowano w kombinacji kontrolnej. Ze środowiska glebowego grochu w fazie kwitnienia izolowano najczęściej grzyby z rodzaju Penicillium, które stanowiły 40,78% izolatów grzybowych oraz z rodzaju Fusarium (32,37%).
