    Opis:
    The analysis of seed health and germination capacity of 7 varieties of Lolium perenne, originated from two breeding station and two seed company localized in different places of Poland, harvested in 2006, 2007 and 2008 were performed. Results of mentioned analysis indicated that seeds were contaminated by numerous species of fungi. The most numerous group of fungi were saprophytes or weak parasites such as: Alternaria alternata, Epicoccum nigrum, Septonema chaetospira and Penicillium spp. Pathogenic species were represented by species of Drechslera, Fusarium, Phoma, Curvularia lunata and Bipolaris sorokiniana. Seed germination capacity was influenced by contamination of fungi. It was found that seed more often contaminated by fungi germinated much poorer then seed with lower infection.

    Opis:
    The spectrum of fungal diversity associated with rape seeds belonging to 33 cultivars (Alaska, Astrada, Astrid, Atlantic, Betty, Champlein, Chayenne, Dexter, Digger, Elvis, Eurowest, Finesse, Herkules, Hydromel, Hydromel-MA, Ladoga, Manitoba, Masa Rom, Milena, Mohican, Montego, Nectar, Ontario, Orkan, Perla (4 lots), Remy, Robust, Rodeo, Saphir, Tiger, Tiger CBC Lot ROM06-121-110, Triangle, Valesca, Vectra) and 2 hybrids (H-90-20-83, H-90-21-83) has been established by samples’ macroscopical and microscopical analizying, during 2006-2008, for the first time in Romania. The Ulster method on malt-agar and PDA culture media has been used, evaluating the percentage of fungal taxons present on/in rape seeds. The most important pathogenic fungi identified were: Sclerotinia sclerotiorum (Lib.) de Bary, Botrytis cinerea Pers., Rhizoctonia solani Kühn, Alternaria brassicae (Berk.) Sacc., A. brassicicola (Schwein.) Wiltshire and Fusarium spp. Also, a large quantities of some saprophytic fungi, as Alternaria, Cladosporium, Aspergillus, Penicillium, Rhizopus have been recorded. These ones have been affected the health condition of rape seeds, suppressing their germination and other vital phenomena. Among potential antagonistic fungi the followiung genera have been isolated: Chaetomium (0-4%), Trichoderma (0-10%), Aspergillus (0-14%), Penicillium (0-100%). Some correlations and comparisons have been established between fungal diversity, their provenience, cultivars, culture media (Malt-Agar/MA, Potato-Dextrose-Agar/PDA) used. It has been evaluated the behaviour of rape cultivars and hybrids towards the main rape seed pathogens.

    Opis:
    Seeds of 5 cultivars of spring barley, originated from field experiments conducted in 2000 at Radzików, were tested immediately after harvest and after three, four and five years of storage in uncontrolled conditions, for incidence of seed-borne fungi with special regard to “field fungi” (Bipolaris sorokiniana and Fusarium spp.) and "storage fungi" (species of Penicillium and Aspergillus). The studies showed that barley seeds were infected before storage by numerous fungi as well as the saprophytes: Alternaria alternata, Acremonium spp., Acremoniella atra and the pathogens: Bipolaris sorokiniana and ten Fusarium species. The analysis after storage showed that the frequency of fungal infection had changed. The occurrence of some fungi was significantly affected by the period of storage...

    Opis:
    Mycelial growth of the pathogenic fungus Ciboria batschiana (Zopf) Buchwald was examined at nine temperature levels between -3°C and +35°C using pure cultures of the fungus from eleven different provenances located in Germany, Poland, the Czech Republic and Slovenia. The fungus was isolated mainly from cotyledons of acorns of the oak species Quercus robur L. and Quercus petraea (Matt.) Liebl. Even at -3°C the mycelium of the fungus grew well. There were significant differences between the provenances in respect to growth rate and temperature tolerance, especially at low temperatures.

    Opis:
    Seeds of the Andean lupine are characterised by high nutritional value, and the plant could become an important crop in the production of food and forage. This legume continues to attract growing interest around the world. A field experiment was carried out in in Lower Silesia, Poland, in 2011-2012. Two Andean lupine morphotypes (indeterminate and determinate) were analysed. Andean lupine was grown in treatments characterised by different sowing dates and plant density per m2. Seed yield, macronutrient content, protein content and health were evaluated at harvest. Seed yield was determined by the interaction of all experimental factors. The indeterminate form produced a significantly higher yield than the determinate form, regardless of the sowing date. The factors had little influence on the mineral content of seeds and total protein content. Andean lupine seeds were colonised mostly by saprotrophic fungi of the genera Alternaria, Cladosporium, Epicoccum and Rhizopus and pathogenic fungi of the genera Botrytis, Colletotrichum and Fusarium. Delayed sowing contributed to seed colonisation by fungi of the genus Colletotrichum. The determinate form was more susceptible to infection than the indeterminate form. Molecular analysis showed that the Colletotrichum isolates found in the study belong to the Colletotrichum acutatum species complex. The pathogen causing lupine anthracnose, isolated from the seeds of Andean lupine in the present study, was identified as Colletotrichum lupini (within C. acutatum complex) in a molecular analysis, and its DNA sequence was compared with those of the isolates deposited in the GenBank.

    Opis:
    Anthracnose disease caused by Colletotrichum lindemuthianum (Sacc. and Magnus) Lams- -Scrib is one of the most devastating seed-borne diseases of common bean (Phaseolus vulgaris L.). In the present study, we evaluated the antifungal activity of Bunium persicum essential oil (EO) and its main constituents on mycelial growth, sporulation and spore germination inhibition of C. lindemuthianum. The main objective of this study was to investigate the effect of EO and its main constituents on decreasing the activity of cell wall degrading enzymes (CWDEs) produced by C. lindemuthianum, which are associated with disease progress. Also, the effects of seed treatment and foliar application of EO and its main constituent, cuminaldehyde, on anthracnose disease severity was investigated. The essential oil of B. persicum, was obtained by using a clevenger apparatus and its major constituents were identified by gas chromatography-mass spectrometry (GC-MS). The EO was characterized by the presence of major compounds such as cuminaldehyde (37.7%), γ-terpinene (17.1%) and β-pinene (15.4%), which indicated antifungal effects against C. lindemuthianum. This pathogen did not grow in the presence of EO, cuminaldehyde and γ-terpinene, β-pinene at 1,500; 1,010 and 1,835 ppm concentrations, respectively. Also, sporulation and spore germination of C. lindemuthianum was completely inhibited by EO and cuminaldehyde. Synergistic effects of the main constituents showed that combing γ-terpinene with cuminaldehyde induced a synergistic activity against C. lindemuthianum and in combination with β-pinene caused an additive effect. Activities of pectinase, cellulase and xylanase, as main CWDEs, were decreased by EO and its main constituents at low concentration without affecting mycelial growth. Seed treatment and foliar application of peppermint EO and/or cuminaldehyde significantly reduced the development of bean anthracnose. We introduced B. persicum EO and constituents, cuminaldehyde and γ-terpinene, as possible control agents for bean anthracnose.

    Opis:
    The objective of the paper was to determine the effectiveness of post-culture liquids of Bacillus sp. Bsch 19 and Pseudomonas sp. Psch 16 in the protection of soybean from soil-borne fungi. The use of post-culture liquids of those bacteria in seed dressing positively affected the number, healthiness and yielding of soybean plants. The plants were mainly infected by Fusarium spp., Phoma exigua var. exigita, Rhizoctonia solani and Sclerotinia sclerotiorum. Those fungi were isolated much more rarely from the plants in combinations with the use of post-culture liquids of antagonistic bacteria as compared with the plants from the control combination, i.e. without seed dressing. A reverse relation was found for the occurrence of saprophytic fungi from the genera of Gliocladium, Penicillium and Trichoderma.
    Celem pracy było określenie skuteczności płynów pohodowlanych Bacillus sp. Bsch 19 oraz Pseudomonas sp. Psch 16 w ochronie soi przed grzybami odglebowymi. Zastosowanie płynów pohodowlanych tych bakterii do zaprawiania nasion wpłynęło korzystnie na liczebność, zdrowotność i plonowanie roślin soi. Rośliny porażone były głównie przez Fusarium spp., Phoma exigua var. exigua, Rhizoctonia solani i Sclerotinia sclerotiorum. Grzyby te wyosabniano znacznie rzadziej z roślin w kombinacjach z zastosowaniem płynów pohodowlanych bakterii antagonistycznych, aniżeli z roślin w kombinacji kontrolnej, tj. bez zaprawiania nasion. Odwrotną zależność stwierdzono w przypadku występowania grzybów saprotroficznych z rodzajów Gliocladium, Penicillium i Trichoderma.
