[Comparative study of the mutagenic activity of dicurin on five test-objects].

Mutagenic activity of dicourol belonging to coumarol derivatives has been studied on 5 test-objects (mice, cultivated lymphocytes of human blood, yeast-saccharomycetes, Tradescantia, Crepis). Results of investigations allowed attributing dicourol to highly hazardous mutagens. In this connection it is admitted unadvisable to enforce it into agricultural practice. The tested objects differ in their dicourol mutagenic sensibility as follows: cultivated lymphocytes of human blood - Tradescantia - yeast - Crepis - mice.
