Variation in the phytotoxic activity of Tinospora tuberculata extracts as influenced by solvent type and chemical profile
A study was conducted to evaluate the role of secondary metabolites on the allelopathic activity of methanol and water extracts obtained from aerial parts of Tinospora tuberculata on seed germination and the radicle and hypocotyl lengths of barnyardgrass. The higher suppressive effects were observed...
