Opis:: W pracy przedstawiono charakterystykę kilku rodzajów biomasy, przydatnej do przetwarzania na biopaliwa stałe, ciekłe i gazowe I, II i III generacji. Zaprezentowano korzyści i zagrożenia, wynikające z niezbędnego zwiększania udziału rolnictwa w energetycznym wykorzystaniu biomasy jako odnawialnego źródła energii (OZE).
Presented are several types of biomass suitable for conversion to solid, liquid and gaseous biofuels of I, II and III generation. Considered are advantages and threats connected with indispensable increase of the share of agriculture in the use of biomass as the Renewable Energy Source (RES).

Opis:: Response of 136 somaclonal lines obtained from 15 winter triticale genotypes (Bolero, Dagro, Grado, Lasko, Moniko, Presto, Ugo, GRH 32-1, KS-24, MAH 15668-1, MAH 15833-1/1, T/8, T/9, T/28, T/47), to Fusarium seedling blight was evaluated. Mixture of five Fusarium species was used for inoculation. Somaclonal lines varied widely in their resistance to Fusarium spp. scored by coleoptile and root infection, and reduction of length of shoot and roots, and seedling weight. Most of the somaclonal lines differed significantly from parental genotypes in at least one of the above parameters. It was found that resistant parental genotypes (e.g. Grado, KS-24) produced mainly more susceptible somaclonal lines and susceptible ones (e.g. Ugo, MAH 15833-1/1) gave rise mainly to more resistant lines. However, some resistant lines originated from resistant genotypes (e.g Presto) were found.

Opis:: The genetic similarity of three species: Septoria tritici, Stagonospora nodorum and Stagonospora avenae f. sp. triticea - important pathogens in many cereal production areas worldwide was assessed by random amplified polymorphic DNA (RAPD) assay. In preliminary research DNA of 14, 9, and 7 monopyenidios- pore isolates of S. nodorum, S. tritici, and S. a. tritícea, respectively, were amplified by PCR with four primers. Afterwards the research was focused on three mono- pyenidiospore isolates from each species studied. The isolates of each species selected for the study varied in pathogenicity and were diverse geographically. PCR with the set of 14 selected primers resulted in 99 different bands, ranged from 180 to 2500 base pairs in length. Most primers in PCR (especially RAD11, RAD31, RAD32, RAD33) revealed uniform bands for isolates of S. a. tritícea, that allow to identify this species among the others. The cluster analysis using Unweighed Pair-Group Method with Averaging (UPGMA) revealed interspecies disagreement among the isolates ranging from 32 to 53%. The intraspecies disagreement ranges were 17-20%, 38-43%, 42-44% for S. avenae f. sp. triticea, S. nodorum and S. tritici, respectively. Cluster analysis classified isolates into three homogeneous clusters. Each cluster grouped isolates of one species according to their current taxonomie ranks based on spore size, colony morphology and host ranges. In addition, two of the clusters represented by isolates of S. nodorum and S. a. tritícea were distinctly separated at a lower linkage distance from the third one comprising isolates of S. tritici. A slight inconsistency found in grouping some isolates indicates that such groupings should be done with caution. The present study indicates that the PCR- RAPD assay is of a potential use in taxonomy of Stagonospora spp. and Septoria tritici as well as in molecular identification of casual disease agents.

Opis:: Stagonospora nodorum produces cell wall degrading enzymes when grown in culture media containing cell wall components. The pathogen grew as well on minimal agar plates containing cellulose, xylan and pectin as glucose, except having sparser mycelia. Four cell wall-degrading enzymes, cellulase, xylanase, pectinase and b-1,3-glucanase were coordinately induced in culture filtrates growing on xyaln and cellulose as substrates. An aggressive isolate (sn26-1) secreted more cell wall-degrading enzymes than the others. Based on isoelectric focusing profiles, six to seven xylanase isozymes were induced by cellulose and xylan. No difference was found in the high (sn26-1) and low (9074) aggressive isolates. Addition of cell wall-degrading enzyme mixtures, not high xylanase alone, to a spore suspension of a low aggressive isolate (9074) caused a limited increase in tissue necrosis. We conclude that the cell wall degrading enzymes play a role in early penetration of the host by the fungus, but they are not important elicitors for disease development.
