The epicuticular wax is the contact point between plants and the environment and plays a crucial role in mediating biotic and abiotic interactions. The associations between the content of epicuticular waxes, on surface plants of winter triticale with their acceptance by the grain aphid Sitobion avenae and bird cherry -oat aphid Rhopalosiphum padi were studied. In general, waxy genotype DED 1137 of winter triticale was less accepted by the cereal aphids than the wax less one (RAH 366). The waxy genotype decreased density of cereal aphids, prolonged maturity and decreased fecundity. Moreover, the comparison of abundance, development and fecundity of the aphid species on the triticale genotypes proved that tested genotypes differed in susceptibility to Sitobion avenae and Rhopalosiphum padi. The importance of the epicuticular wax compounds in the acceptance of plants by the aphids is discussed. The results indicated that aphids fed on waxy plants showed longer time of the prereproductive period and much lower total fecundity. Furthermore, waxy genotype reduced value of the cumulative aphid index and percentage of infested plants.

The surface chemicals occurring within epicuticular wax layer of heavily covered with waxes and wax-less triticale were analysed. Dichloromethane extracts of flag leaves and ears were separated using gas chromatography and mass spectrometer GC-MS, Shimadzu QP 5050A, equipped with Zebron ZB-5 column (30 m x 0,25 mm). Obtained results showed the 14,16-hentriacontanedione (C₃₁H₆₀O₂) and lauric acid 2-(hexadecyloxy)-3-(octadecyloxy) propyl ester (C₄₉H₉₈O₄) only in extracts from the heavy waxy cultivar. Thus further study is needed to confirm if these compounds play an important role as triticale resistant factors towards the grain aphid.

Rabbits exposed repeatedly to aerosols of endotoxin-containing microvesicles (ECMV) of the outer membrane of the Pantoea agglomerans strain isolated from airborne grain dust showed a large increase in the concentration of circulating cytokines: total interferon (IFN), interleukin-1 alpha (IL-1 alpha), and tumor necrosis factor alpha (TNF alpha). The increase was significantly higher compared to animals exposed to control saline (p<0.001). Aerosol exposure to ECMV also induced the formation of specific precipitin antibodies and lymphocyte activation. The results indicate strong immunomodulative properties of ECMVs produced in nature by Pantoea agglomerans bacteria, and heavily contaminating organic dusts.

W pracy dokonano analizy statystycznej metodą regresji wielokrotnej wpływu czynników meteorologicznych i glebowych na wartości temperatury radiacyjnej pokrywy roślinnej. Stwierdzono, iż wprowadzenie do modelu regresji wielokrotnej potencjału wody glebowej jako zmiennej niezależnej poprawia dokładność predykcyjną modelu w przypadku, gdy zmienną zależną jest różnica temperatury pokrywy roślinnej w sytuacji stresu wodnego i przy nieograniczonej dostępności wody glebowej. Przedstawiono zależność temperatury powierzchni roślin od temperatury powietrza, prędkości wiatru, radiacji słonecznej i potencjału wody glebowej.
