The fungal population colonizing the seeds of fodder galega cultivated in pure stand was greater than that cultivated in mixed stand. No significant differences were observed in the species composition of the obtained fungal colonies. In all analyzed combinations, Alternaria alternata was predominantly isolated from the seeds. Other saprophytic fungi were represented by the following species: Epicoccum purpurascens, Cladosporium cladosporioides as well as fungi representing genera Mucorales: Mucor hiemalis and Rhizopus nigricans. Among the pathogens, Botrytis cinerea was most often isolated. The mineral and SNA medium as well as the process of superficial disinfecting of seeds reduced the number of isolated fungi.

AbstractThe effect of 15 fungi species most frequently inhabiting grapevine shoots on the growth of Phoma negriana was examined. Particular species-components of the fungal community were tested in vitro against the pathogen, using the biotic series method. The majority of fungi species inhibited P. negriana growth and the growth of only 3 species from the community, i.e. Alternaria alternata Keiss., Botrytis cinerea Pers. and Phomopsis viticola, was limited by the pathogen. Fungi Trichoderma were found the most effective against P. negriana. They completely degraded the hyphae and conidia of P. negriana after 20–22 days of growth in two-organism cultures. The summary biotic effects of fungal communities from grapevine were generally favourable to the P. negriana growth and only in one year of study they suppressed the pathogen development.

Economic losses incurred during raspberry storage are primarily a result of fungal spoilage. This study aimed to characterise the micromycete phytopathogenic complex in stored raspberries. The fungal microbiome was assessed in six Russian raspberry cultivars (Cleopatra, Novost’ Kuzmina, Sulamiph, Fregat, Shakhrazada, Yarkaya) as well as three foreign varieties (Glen Lyon, Cascade Delight, Limonnaya). The economic and biological traits of the cultivars were studied within the “Programme and Protocol for Fruit, Berry and Nut Crops Varietal Testing”. Internal and surfacelevel contamination in infected fruit tissues was detected via the stimulation of microbial growth in a wet chamber. The micromycete species composition was assessed via commonly used methods. The following raspberry spoilage organisms were identified as being predominant. Rots: black (Alternaria alternata (Fr) Keissler), dry (Fusarium Link.), leather (Phytophthora cactorum (Leb. et Cohn) Schroet), grey (Botrytis cinerea Pers.); moulds: black (Cladosporium Link.), green-blue (Penicillium Link.), green-yellow (Aspergillus P. Micheliex Haller), grey capitate (Rhizopus nigricans Ehrenb.), capitate (Mucor spp.); drupe rot (Phragmidium rubi Wint.); bacterioses. Microbiotic profiles varied between cultivars in storage. The fungal genera Fusarium and Alternaria prevailed, with the former dominating in almost all samples. The phytopathogenic complex primarily consisted of the fungal genera Fusarium, Alternaria and Penicillium. Raspberry cultivars which had a weak (Sulamiph, Shakhrazada, Novost’ Kuzmina) or strong (Cleopatra) resistance to micromycetes in storage were identified.

SUMMARYAll four seed diffusates used for treatment of sunflower seeds, Azadirachtaindica, Capsicum annuum, Coriandrum sativum and Eugenia jambulana, reduced the populations of seed-borne fungi: Alternaria alternata, Drechslera tetramera, Emericellopsis terricola, Fusarium moniliforme, F.semitectum, Macrophomina phaseolina and Phoma oleracea. Of four seed diffusates, those from A.indica and C.sativum controlled the fungal populations almost 100%. Seed germination was increased in seed samples of both sunflower cultivars under study, HO-1 and NK-212. The obtained results indicate that seed diffusates could substitute costly chemicals for safe control of seed-borne diseases, protecting at the same time the environment from chemical pollution.

Waste exogenous organic matter, including spent mushroom substrate (SMS) and chicken manure (CM), can be used as the basis of a soil-improving cropping system in sustainable agriculture. However, there is—as yet—a lack of information about important quality indicators such as the fungal community relative abundance, structure and biodiversity in soils treated with these additives. In this study, the responses of the soil fungal community composition and mycobiome diversity to SMS and CM application compared to the control soil were evaluated using a combination of the following molecular approaches: quantitative polymerase chain reactions, denaturing gradient gel electrophoresis, terminal restriction fragment length polymorphism, and next-generation sequencing. The most abundant phylum for both treatments was Ascomycota, followed by Basidiomycota. The application of SMS and CM increased the abundance of fungi, including Tremellomycetes and Pezizomycetes for the SMS additive, while the Mortierellomycetes, Pezizomycetes, and Leotiomycetes levels increased after CM addition. SMS and CM beneficially reduced the relative abundance of several operational taxonomic units (OTUs) which are potential crop pathogens. The results provide a novel insight into the fungal community associated with organic additives, which should be beneficial in the task of managing the soil mycobiome as well as crop protection and productivity.

Visits of honeybees (Apis mellifera L.) and bumblebees (Bombas spp.) to flowers of field bean (Vida faba L.), goat’s rue (Galega orientalis Lam.) and spring turnip rape (Brassica rapa ssp. oleifera DC.) were studied to get some basic knowledge about the species composition, abundance and daily rhythm of bees visiting these plants. The studies were made under field conditions. Only pollinating specimens were counted. Both on field bean and goat’s rue 44% of the visitors were honeybees, on turnip rape the proportion of honeybees was 96%. Field bean was visited by Bombas subterraneus (L.)/B, hortorum (L.) as well as by B. lucorum (L.). These species were also present on goat’s rue; the most numerous bumblebee species on this plant, however, was B. lapidarius (L.) which was also the only bumblebee species visiting turnip rape. The total number of bees was highest on goat’s rue. The visits of honeybees began on field bean at noon and were most numerous in the afternoon. On goat’s rue, the numbers were smaller in the mornings, whereas turnip rape was visited at a rather constant rate throughout the day. On field bean, the numbers of B. subterraneus/B. hortorum increased and those of B. lucorum decreased towards the afternoon. On goat’s rue, these species were present in the morning and in the afternoon. B. lapidarius was present on goat’s rue during the whole day, but on turnip rape only in the mornings. On the basis of these results and earlier investigations it is concluded that the numbers of natural pollinators are rather low to assure adequate pollination in turnip rape and large field bean areas under the conditions in southern Finland. If the growing of goat’s rue becomes more prevalent, its pollination requirements need further studies.

Seeds of 11 Austrian winter pea genotypes, harvested at Radzików (CEP) in 1993 and 1994, were evaluated for fungi occurrence on Coon's agar medium in Petri plates. Number of species isolated depended on the genotype and year of collection. <i>Alternaria alternata, Stemphylium botryosum</i> were found on all the tested samples and <i>Phoma pinodella</i> and <i>Fusarium poae</i> were also common while <i>Botrytis cinerea, Sclerotinia sclerotiorum</i> and <i>Mycosphaerella pinodes</i> appeared to be common only in 1993. Three species occurred only once. The mycoflora was richer in 1993. The common seed inhabitants usually transmitted higher percentage of fungi than species occuring more seldom.

The purpose of this study, conducted in the years 2000 - 2002, was to identify fungi species colonizing apparently healthy canes and to investigate whether canes storage modify the quantitative and qualitative composition of these fungi. The plant material was collected from 5 commercial plantations growing in various regions of Poland, taking into consideration 8 cultivars which were the most frequently cultivated. From each plantation and cultivar 20 apparently healthy canes were randomly sampled in two terms: before storage - November/December (term I) and 3-4 months after storage - February/March (term II). The results showed that from asymptomatic canes 2746 isolates of fungi belonging to 23 species were obtained, but the majority of them origined from canes analysed after storage. It was found that <i>P. viticola</i> is able to live latently within grapevine tissue in Polish conditions because isolates of this fungus from visually healty canes the all studied plantations and terms were obtained. Among the other fungi species inhabiting grapevine canes <i>Alternaria alternata</i> and <i>Fusarium</i> spp. dominated. Moreover, both in term I and term II <i>Botrytis cinerea</i>, <i>Phoma</i> spp., <i>Epicoccum purpurascens</i> and <i>Cladosporium cladosporioides</i> were frequently isolated, whereas fungi from the genus <i>Acremonium</i> only in the term I. Each time isolates of <i>Trichoderma</i> spp. and <i>Gliocladium</i> spp. were also obtained. Inhabitation of grapevine canes by various fungi species shown in the present experiment indicate the danger of pathogens spread with propagation material on the new plantations.
