It is shown that aqueous extracts from bird cherry tree Padus avium L., aspen Populus tremula L., and celandine Chelidonium majus L., effectivily suppress the germination of Puccinia triticina Eriks uredospores. Fungitoxic activity of the extracts is supposed to be determined by high content of phenolic compounds and high peroxidase activity in the leaves of these plants. Fungitoxic activity of the extracts from the leaves, inflorescences, roots, and stems of siberian cowparsnip Heracleum sibiricum L., was also correlated with the content of phenolic compounds in these organs. Treatment of healthy wheat Triticum aestivum L., cv. Lyubava, with the extracts from common comfrey Symphytum officinale L., cowparsnip Heracleum sibiricum L., and giant knotweed Reynoutria sashalinensis (F. Schmitt) Nakai, stimulated the photosynthetic activity in treated leaves.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
