Description of key information
At a concentration of 0.01 and 0.1% cinchonidine inhibits germination and growth. Thus, cinchonidine has phytotoxic effects.
Key value for chemical safety assessment
Additional information
In the publications of Wink, 1992 and 1998 the inhibition of root and hypocotyl growth of Lepidium sativum and Lactuca sativa were determined for concentrations of 0.01% and 0.1% cinchonidine. Inhibitory effects were observed at a concentration of 0.01% (100 mg/kg soil) cinchonidine for Lactuca sativa and concentration of 0.1% (1 g/kg soil) cinchonidine for Lepidium sativum. These results indicate that cinchonidine has phytotoxic effects.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
