Abstract

Three cytokinin-active ureas, N-phenyl-N′-(2-hydroxy-4-pyridyl)urea, N-2-methylphenyl- N′-(2-hydroxy-4-pyridyl)urea and N-pbenyl-N′-(6-hydroxy-4-pyridazinyl)urea, were found to have growth-stimulating activity in the rice seedling test. Their structure-activity relationships are discussed.
