文摘wenty-eight new N-2-thiazolyl and thiazolinyl-N'-substituted phenylureaswere synthesized by the reaction of the heterocycles and substituted phenyl iso-cyanates. Their cytokinin activity was examined by cucumber cotyledon expansionbioassay. N-thiazolyl and N-thiazolinyl-N'-(m-chlorophenyl )-ureas showed a goodPGR activity in comparison to Kinetin.
