Startek, L. (Akademia Rolnicza, Szczecin (Poland))
The experiment was conducted on seven F1 cultivars of pansy of Delta Group from firm Novartis. It was aimed at examining the influence of retardants: B Nine 85 SP at concentration of 0.5 percent, Cycocel 460 SL - 0.5 percent, Topflor 015 SL - 0.05 percent on morphological features of pansies. Sphagnum peat (pH=6.5) was used as a medium, in four fertilization combinations. It was found that only Topflor 015 SL had strong retarding and long lasting effects. Cycocel 460 SL inhibited growth of all the cultivars for a short period of time, but improved plant conformation. B Nine 85SP had the weakest stunting properties. The pansies in combinations with Csmocote Plus, slow-release fertilizer, had the largest flowers and the most abundant flowering
