Foliar application effects of salicylic acid (SA) and gibberellic acid (GA₃) were investigated on growth and flowering of Ixora coccinea L. plants. Four concentrations (100, 200, 300 and 400 ppm) of both SA and GA₃ were sprayed in addition to the control (water-sprayed plants). Results indicated that all growth and flowering characteristics of Ixora plants were increased by all concentrations of SA or GA₃ compared to the untreated plants. Concerning salicylic acid, the lowest concentration (100 ppm) produced the highest plants while 200 ppm increased leaf area and shoot/root ratio. Number of leaves and plant pigments (chlorophyll a, b, a+b and carotenoids) were increased at 300ppm concentration. Spraying the plants with 400ppm increased fresh and dry weight of shoots and roots and flower number. GA₃ sprayers at 300 or 400ppm led to a significant increase in most of the characteristics studied in comparison to the untreated plants. The correlation coefficient among most of Ixora vegetative and flowering growth characteristics proved to be significant.
