Evaluation of the phytotoxic effect of extracts from endophytic fungi Colletotrichum dianesei and Xylaria sp. isolated from Palicourea corymbifera (Rubiaceae)
Abstract:The allelopathic action can be verified by the presence of phytotoxic substances, molecules that are directed to the agribusiness sector. The objective of this study was to evaluate the chemical composition of the methanolic extracts from Colletotrichum dianesei and Xylaria sp., and phytotoxic potential on Lactuca sativa. The fungi were grown in Sabouraud liquid medium supplemented with 0.2% yeast extract, under stirring. The mycelia were subjected to solvent extraction in order of increasing polarity, but met… Show more
