The object of the experiment were seeds of two traditional cultivars of yellow lupin (Juno and Amulet) cultivated in 1999 in two crop-rotation with 20% and 33% yellow lupine contribution. The quantitative and qualitative composition of the fungal community colonizing the seeds were determined in the laboratory conditions after 0.5-, 1.5- and 2.5-year of storage time. In total 1077 fungal colonies were isolated from the lupin seeds. Fungi representing the species of Penicillium - 29.3%, Alternaria alternata - 26.7% and Rhizopus nigricans - 12.7% were isolated most widely. Among the fungi pathogenic to lupin, the species of Colletotrichum gloeosporioides (16.3% isolates) was dominant. The crop rotation with 20% lupin reduced the number of fungal colonies colonizing the seeds including the pathogens from the species of C. gloeosporioides. Seed disinfection decreased the total number of fungal colonies isolated from both cultivars. Higher number of C. gloeosporioides isolates was found in the combination with disinfected seeds. More fungal colonies were obtained from seeds of cv. Amulet than from those of cv. Juno. The storage duration had an effect on the population and the composition of species of fungi isolated from seeds of yellow lupine. With longer storage population of Penicillium spp. and Rhizopus spp. increased, whereas the population of C. gloeosporioides decreased.

The aim of studies was to determine typical composition of fungi occurring on seeds of Stewartia pseudocamellia.The studies conducted on 100 disinfected and 100 nondisinfected seeds of these plants. Isolates of Alternaria alternata, Fusarium oxysporum, Cylindrocarpon radicicola and Rhizoctonia solani were characterized by pathogenicity towards the investigated Stewartia pseudocamellia. In the laboratory experiment, 204 isolations of microorganisms were obtained that belonged to 20 species and form of fungi and bacteria. Among fungi there were both of parasite (Alternaria alternata, Botrytis cinerea, Fusarium spp., Rhizoctonia solani) and typical saprophytic (Cladosporium spp., Penicillium spp., Aspergillus spp., Epicoccum spp., Mucor spp.). The dominant fungus on seeds was Alternaria alternata. Among the investigated isolates only one isolate (R₄) Rhizoctonia solani, was strongly pathogenic, isolates (A₁) Alternaria alternata were weakly pathogenic to seedlings of Stewartia pseudocamellia.

Seeds of Abutilon theophrasti grown in Poland were colonized at least by 11 species of fungi. Alternaria alternata was the most common species. Its frequency in the fungal community amounted to 62%. Epicoccum nigrum and Aspergillus spp. were also common fungi on/in seeds, occurring usually with local or temporal peaks. Other fungi, including Fusarium, Botrytis cinerea, Sclerotinia sclerotiorium and Trichothecium roseum occurred sporadically.

The research was conduced in the years 1999-2000. The aim of the research was to determine the health condition of overground parts and seeds of the following spring oilseed crops: crambe (Crambe abbysinica Hoechsl.) cv. B o r o w s k i, false flax (Camelina sativa L.) cv. B o r o w s k a, spring rape (Brassica napus ssp. oleifera L.) cv. M a r g o and oleiferous radish (Raphanus •tivus var. oleiferus L.) cv. P e g 1 e t t a. In all the years of the research alternaria, light was found on the leaves and siliques of spring rape and oleiferous radish and on the leaves and stems of crambe. False flax proved to be weakly infected by •pathogens. On its leaves gray mould (Botrytis cinerea) was found in all the years, of the research. The disease was found on the siliques only in 1999. In 2000, powdery mildew was found on spring rape and false flax (respectively, Erysiphe cifearum and E. cichoracearum). The weather conditions affected the intensity the diseases on the studied spring oilseed crops. Alernaria genus, especially A. alternata was most commonly isolated from the of examined p!ants. It constituted from 37% (in crambe) to 63.3% (in spring) of all the isolates. Of the remaining pathogenic species, numerous fungi of Fusarium genus (F. avenaceum, F. culmorum, F. equiseti and F. oxysporum) isolated. They constituted from 1.0% (false flax) to 17.3% (crambe) of the isolates.
