Abstract
Ruellia simplex C. Wright is an ornamental plant with a high capacity to adapt to various environmental conditions and rapid vegetative growth characterized by elongated internodes. However, it produces relatively few flowers with small flower size and a short flowering period, thereby reducing its ornamental value. Therefore, the application of paclobutrazol in combination with different types of foliar fertilizers is expected to overcome these limitations. This study aimed to analyze the interaction between paclobutrazol application and different types of foliar fertilizers, as well as to determine the optimum paclobutrazol concentration and foliar fertilizer type for promoting the growth and flowering of Ruellia simplex. The experiment was conducted using a two-factor factorial Completely Randomized Design (CRD). The first factor consisted of four paclobutrazol concentrations (0, 50, 100, and 150 ppm), while the second factor comprised three types of foliar fertilizers (Gaviota, Growmore, and Gandasil-B). The results demonstrated a significant interaction between paclobutrazol concentration and foliar fertilizer type on internode length and the number of branches at 28 days after planting (DAP). Paclobutrazol concentration as a single factor significantly affected the growth and flowering of Ruellia simplex. The application of 50 ppm paclobutrazol was found to be the optimum concentration for enhancing the growth and flowering performance of potted Ruellia simplex.
