Agents for regulating the growth of plants are described which correspond to the formula: <IMAGE> where R<1> represents a carboxy radical or a corresponding salt suitable in agriculture, or an alkoxycarbonyl radical, R<2> represents an optionally substituted phenyl radical, R<3> represents an alkyl radical, and R<4> represents a hydrogen atom or an alkyl or halo radical. These compounds can be used in particular for the production of hybrid cereals by induction of male sterility. |
