Abstract—Effects of uniconazole-P and paclobutrazol foliar application on the growth and flowering of Euryops pectinatus Cass. were investigated. Uniconazole-P was more effective than paclobutrazol in inhibiting stem elongation. Uniconazole-P at 12.5 mg/l was suitable for culture in pots 9–12 cm in diameter. To increase the number of flower-bearing shoots, the timing of uniconazole-P application was also examined. The most effective treatment was duplicate application, the first 10–14 days after pinching and the second 2 weeks after the first treatmant. Uniconazole-P decreased the node number necessary for flower bud differentiation of Euryops pectinatus Cass. to 4-5.
