COMPARATIVE EFFECTS OF SOME EXTRACTION SOLVENTS ON THE ANTIOXIDANT, ANTIFUNGAL AND BIOHERBICIDES ACTIVITY OF IN VITRO CONDITIONS OF CRAMBE ORIENTALIS CRUDE EXTRACTS
MetadataShow full item record
There arc important benefits in finding environmentally friendly methods that can replace pesticide in some plant biotic stress factors, by integrated pest management principles. Besides, it is a necessity to improvement and adapt alternative methods or technical to chemical control to sustainable apiculture plant productions. This study was carried out to determine extracts obtained from the Crambe oriantalis naturally grown in Ktrwhir (Turkey) locations, total phenolics, total flavonoids. antioxidant, anti fungal and bioherbicidal activity. In the study, 1.1dipheny1-2-picrylhydrazyl (DPPH), Trolox Equivalent Antioxidant Capacity (TEAC). Ferric ions (Fe3+) reducing antioxidant power assay (FRAP), Copper Reduction Power Activity (CUPRAC), Total phenolic and Flavonoid analyzes of plant extracts were investigated. The antifungal activity of plant extracts was determined against Alternaria solani, Rhizoctonia solani, Verticillium dahliae and Fusarium oxysporm f. sp. radicis-lycopersici, Also, the bioherbicidal activities of the extracts in the Amaranthus retroflexus L. and Rumex en spas L seed germination and seedling development were also examined, As a result of the antioxidant study, it was determined that different chemical solvent extracts obtained from the plant had remarkable antioxidant activity. The total phenolic and flavonoid were determined to be limit in terms of C. orientalis. On the other hand, methanol extracts decreased mycelial growth of pathogens at different rates due to increasing doses, while the highest doses of sterile distilled water extracts inhibited 100% in vitro conditions. In the bioherbicidal study, it was determined that different plant extracts had significant herbicidal effects on A. retroflexus and R. crispus plants for germination and seedling development in vitro conditions.
