| Summary: | The effect of fungicides derivatives 1,2,4-triazole (propiconazole, tebuconazole and cyproconazole) on the bioelectrical characteristics of Nitella flexilis cell was investigated. It was established, that the fungicides differed jast as on the values of concentration capable to cause shifts of electrical potential and membrane resistance, so on the character electrophysiological reaction of cell. It is supposed, that observed membrane effects are result of direct action exogenous triazoies in concentration 10“°—10-" M on plasmamembrane. Probably, the N1-assistant structure in a molecule triazole is determining factor in character registered reaction of plant cell.
