Compounds having an effect on modifying the physiology of plants in various ways have the formula ##STR1## wherein R is H, alkyl, halogenated alkyl, cycloalkyl, naphthyl, phenyl or halogenated phenyl, and R is preferably alkyl of 2-5 carbons, naphthyl, phenyl or chlorinated phenyl.

Plant regulating compounds

Compounds corresponding to the general formula: ##STR1## in which R represents hydrogen, an alkyl radical, a halogenated alkyl radical, a cycloalkyl radical, an optionally substituted aryl radical, an optionally substituted aralkyl radical, an acyl radical, aroyl radical or an optionally substituted heterocycle; R.sub.3 represents hydrogen, aralkyl radical containing 1 to 5 carbon atoms; R.sub.2 represents hydrogen, an alkyl radical (optionally halogenated or substituted by a hydroxyl), a formyl radical, an acyl radical, a carbamoyl radical monosubstituted or disubstituted on the nitrogen; R and R.sub.2 cannot both represent hydrogen; X represents oxygen or sulphur, and their salts, especially their sulphonium salts. Such compounds are useful for modifying the growth of plants.

Hydantoin derivatives and methods for regulating plant-growth

Compounds corresponding to the general formulae: ##EQU1## in which R represents hydrogen, an alkyl radical, a halogenated alkyl raal, a cycloalkyl radical, an optionally substituted aryl radical, an optionally substituted aralkyl radical, an acyl radical, aroyl radical or an optionally substituted heterocycle;
