Abstract
The content and homologue composition of alkylresorcinols were investigated in rye seedlings (Secale cereale L.) treated with benzimidazole fungicides and grown for 5 days under various thermal and light conditions. The fresh and dry biomasses of green and etiolated plants were greatly increased by benomyl and carbendazim at 29 °C. At 22 and 15 °C benomyl had an inhibitory action on growth of rye, whereas the effects caused in the presence of carbendazim were slightly dependent on external stimuli. On the other hand, benomyl enhanced resorcinol biosynthesis in green seedlings grown at all temperatures, while carbendazim only at 29 °C. In plants kept in the darkness, both fungicides increased content of alkylresorcinols at 29 °C and decreased its at 22 and 15 °C. The qualitative pattern of resorcinolic homologues was also significantly modified in the presence of benomyl and carbendazim and depended on other physical stimuli.
