Transplants of Impatiens walleriana ‘Cajun Lilac F1’ were
grown in a greenhouse in pots in a peat substrate with the addition of sand. Daminozide, chlormequat and
flurprimidol were used 1-3 times at 14-day intervals in foliar and soil applications. In May plants were
transplanted to the soil. The dynamics of growth and flowering were investigated in plants grown outdoors.
The strongest and longest-lasting inhibitory effect on the growth of bedding plants was found for daminozide and
chlormequat in foliar application. Soil-applied flurprimidol had a stronger dwarfing effect than daminozide and
chlormequat. Flurprimidol and chlormequat applied to the soil twice at a concentration of
690 mg l-1 had a positive residual effect on plant flowering.
