ABSTRACT (TIMES NEW ROMAN 10 BOLD)
Impatiens balsamina L. is well known as garden balsam that flowers are very usefull. The flowers can be arranged in coconut leaves for praying or as a decoration in pots. Garden balsam plants are tall. The flowers are easy to decay especially in rainy season. Vigorous plants with bigger flower for potted plant can be produced by using oryzalin throughseedlings treatment of garden balsam. Seedlings were treated in oryzalin at concentrations of 0, 0.01, 0.02 and 0.03% for 0, 12, 24, 36, and 48 hours, then grown in the field. As a result, for M1 generation, interaction between oryzalin concentration and incubation time was significant for plant height, number of branch and flower weight. Plants height decreased about 54% for treatmentof 0.01% oryzalin in 48 h incubation. Oryzalin application also increased the weight of flower. In the next generation (M3), mixoploid plants were obtained from treatment 0.02% oryzalin for 12 h incubation. Based on this study, oryzalin can be used for producing compact potted plants.
