Phytotoxic activity of differents plant parts of Drimys brasiliensis miers on germination and seedling development
The aim of this study was to evaluate the phytotoxic activity of aqueous extracts from mature leaves, stem bark and roots of Drimys brasiliensis Miers on germination and initial seedling development of two target species, Triticum aestivum L. (wheat) and Raphanus sativus L. (radish). The aqueous ext...
