Heterocyclic tertiary alcohol compounds useful as plant growth regulators have the general formula (I) :
wherein n is an integer which is 0 or 1; X is S or O; R¹ is an optionally substituted secondary or tertiary alkyl group or an optionally substituted cycloalkyl or alkylcycloalkyl group containing a total of from 3 to 7 carbon atoms; R² is a group : -(CH₂)a-C≡C-A (II) or -(CH₂)b-CH=CH-A (III) or -(CH₂)c-A (IV) or -CH₂-O-(CH₂)d-A (V) wherein A is an optionally substituted aryl group, a, b and d are integers from 0 to 2 and c is an integer from 0 to 4; or R² is an optionally halo-substituted alkyl, cycloalkyl, cycloalkylalkyl alkylcycloalkyl group or alkylcycloalkylalkyl, or is an optionally halo-substituted alkenyl, cycloalkenyl, cycloalkenylalkyl, alkylcycloalkenyl or alkylcycloalkenylalkyl group, or is an optionally halo-substituted alkynyl group each of said groups containing a total of from 4 to 8 carbon atoms; R³ is hydrogen, an alkyl group containing from 1 to 4 carbon atoms or an alkenyl or alkynyl group containing from 3 to 4 carbon atoms.
