An experiment was conducted to evaluate the growth and flowering performances of different colors of roses. Five different treatments, representing different rose colors, were tested: T1 (Red), T2 (Orange), T3 (Dark Pink), T4 (Yellow), and T5 (Light Pink). Each treatment was replicated five times using a Randomized Block Design. This setup allows for a systematic evaluation of how different rose colors impact plant development and flower production. The study monitored various growth parameters, including plant height, leaf number, branch number, bud number, and flower number, at different stages: 7, 14, 21, 28, 35, and 42 days after transplantation (DAT). The results indicated that plant height, leaf number, branch number, and bud number did not significantly vary among the different rose color treatments across most observation periods. Notably, the T3 (Dark Pink) treatment showed good results in plant height and leaf number at later stages. Significant difference was observed at 42DAT in bud numbers where T2(orange) was found to be highest. Significant differences were also observed in flower numbers at 14DAT and 21DAT, with T1 (Red) and T2 (Orange) treatments displaying higher flower counts compared to other treatments. These findings suggest that while certain rose colors may influence flower production and bud numbers at specific growth stages, the overall choice of rose color may not significantly affect other growth parameters like plant height, leaf number and branch number. This research provides insights for growers into selecting rose varieties based on flower color and highlights the need for further investigation into the physiological mechanisms driving these differences.
