| Description
| - Three Lycopersicon spp. accessions differing in the level of resistance to Oidium neolycopersici L. Kiss (tomato powdery mildew) were studied. Defence reactions occurring in tissue of Lycopersicon esculentum cv. Amateur (susceptible control), Lycopersicon hirsutum f. glabratum (LA 2128) (highly resistant) and Lycopersicon chmielewskii (LA 2663) moderately resistant) were investigated during the first 120 h post-inoculation (hpi). A hypersensitive reaction was detected after 48 hpi in both resistant tomato accessions. Changes in accumulation of hydrogen peroxide and enzymes involved in its metabolism (catalase, peroxidases, superoxide dismutase) were monitored. In resistant accessions, intensive H2O2 production correlated with increased activity of cytosolic guaiacol peroxidase, syringaldazine peroxidase and ascorbate peroxidase. Catalase activity increased especially in moderately resistant L. chmielewskii. A similar degree of lipid peroxidation occurred in all Lycopersicon accessions. An increase in

- Byly studovány tři genotypy Lycopersicon spp. lišící se úrovní rezistence k Oidium neolycopersici L. Kiss (tomato powdery mildew). Obranná reakce vyskytující se v pletivu Lycopersicon esculentum cv. Amateur (citivá kontrola), Lycopersicon hirsutum f. glabratum (LA 2128) (vysoce rezistentní) and Lycopersicon chmielewskii (LA 2663) středně rezistentní) byla sledována v průběhu 120 h po inokulaci (hpi). Hypersenzitivní reakce byla detekována po 48 hpi v obou rezistentních genotypech. Dále byly monitorovány změny v akumulaci peroxidu vodíku a enzymů podílejících se na jeho metabolismu (katalasa, peroxidasy, superoxiddismutasa). V rezistentním genotypu korelovala intenzivní produkce H2O2 se zvýšenou aktivitou cytosolické guajakolové peroxidasy, syringaldazinperoxidasy a askorbátperoxidasy. Katalasová aktivita vzrůstala zejména u středně rezistentního genotypu L. chmielewskii. U všech testovaných rostlin byl zaznamenán podobný stupeň lipidické peroxidace. Opět u všech genotypů byl sledován v průběhu 120 hp (cs)
