The invention relates to 6-substituted 9-halogenalkyl purine derivatives of the general formula I wherein R6 is selected from the group comprising -NH-furfuryl, -NH-(4-hydroxy-3-methylbut-2-en-1-yl), -NH-(3-methylbut-2-en-1-yl), -NH-(4-hydroxy-3-methylbutyl), -NH-(4-hydroxy-1,3-dimethylbut-2-en-1-yl), -NH-(4-hydroxy-1,3-dimethylbutyl), -NH-benzyl, -NH-phenyl, wherein benzyl, furfuryl and phenyl can be unsubstituted or optionally substituted with 1 to 3 substituents selected from the group comprising hydroxy, halogen, methyl and methoxy, and R9 is selected from the group comprising C1-C3 alkyl or C1-C3 alkenyl wherein each of the groups is substituted with one or more halogen atoms, for use in the regulation of growth and development of plant cells, organs and/or whole plants. The invention also relates to preparations containing these derivatives and to novel to 6-substituted 9-halogenalkyl purines.˙
