Abstract: 

In order to study the effect of CPPU growth regulator on qualitative characteristics of cut rose (Rosa hybrida cv. Avalanche), an experiment was performed as factorial, based on a completely randomized design, with four replications. In this experiment, the first factor included four concentrations of CPPU (0, 25, 50 and 100 mg/L) and the second factor was two application positions of CPPU (on the stem, and on the bud with a half cut ring 1 cm above the bud). The results showed that bud break, flowering time, length and diameter of flower shoot, flower diameter, number of internodes and fresh and dry weight of flowering stem were significantly (P<0.01) affected by CPPU treatments. The earliest bud break and flowering, longest stem, highest shoot and flower diameter and the highest stem fresh and dry weight were observed in the 50 mg/L CPPU treatment. However, application position of CPPU on the stem did not show any significant effect on the studied traits. Based on the results of this experiment, using CPPU growth regulator can increase growth of basal buds and enhance qualitative properties of the cut roses.
