Abstract

Influence of different concentrations of daminozide (Alar 85) on the growth and flowering of Solidago x hybrida cv. Goldwedel, grown from terminal and subterminal cuttings, was investigated during two years. Plant height and the number of inflorescences per plant were the variables measured in order to assess the potentials of its cultivation as a pot plant. Different daminozide concentrations were shown to have the strongest influence on flowering. Plants grown from subterminal cuttings were by 22% shorter than plants grown from terminal cuttings. Application of Alar 85 as growth retardant had no significant effect on plant height reduction, and it even produced an adverse effect in the case of subterminal cuttings. A 0.4% concentration of Alar 85 had a positive effect on plant diameter. These results point to the possibility of growing Solidago x hybrida cv. Goldwedel as a pot plant without daminozide application.
