Abstract
Abstract Growth retardants [ancymidol (0.1-1.0 mg·liter −1 ), chlormequat (0.5-500 mg·liter −1 ), and paclobutrazol (0.1-1.0 mg·liter −1 )] reduced shoot extension, promoted root initiation, and increased root weight in apple seedlings ( Malus domestica Borkh ‘York Imperial’). The induction of root formation and increase in root weight were accompanied by a considerable increase in polyamine levels. Daminozide (0.1-250.0 mg·liter −1 ) and dikegulac (0.25-500 mg·liter −1 ) also inhibited apple seedling growth; however, these compounds did not promote rooting. Chemical names used: α-cyclopropyl-α-(4-methoxyphenyl)-5-pyrimidinemethanol (ancymidol); 2-chloro- N,N , N -trimethylethanaminium chloride (chlormequat chloride); butanedioic acid mono(2,2-dimethylhydrazide) (daminozide); 2,3:4,6-bis- O -(l-methylethylidene)-α-L- xylo -2-hexulofuranosonic acid (dikegulac); β-(4-chlorophenyl)methyl]-α-(l,l-dimethylethyl)-l H -1,2,4-triazole-l-ethanol (paclobutrazol).
