To develop Korean native lilies as mini-potted plants, the effects of plant growth retardants on inhibiting stem elongation and improving flowering rate were evaluated. Bulblets of Lilium concolor var. parthneion (5-7 g) and L. dauricum (3-4 g fresh wt) derived from in vitro culture and then enlarged by field culture were applied with 0, 25, 50, or 100 ㎎ㆍL⁻¹ ancymidol, diniconazole, and uniconazole through bulb dipping, foliar spray, and drench. In L. concolor var. parthneion, uniconazole dipping most effectively reduced plant height by 60.7-78.3% depending on concentration compared with control without decreasing flowering percentage. In L. dauricum, dipping into diniconazole solution significantly retarded the plant height by 70.0-86.3% and improved flowering percentage by 8.3-18.2% compared to control of 0%. Drench of 25-50 ㎎ㆍL⁻¹ ancymidol was also effective on inhibition of stem elongation and improvement of flowering rate. Therefore, dipping into 50-100 ㎎ㆍL⁻¹ uniconazole solution in L. concolor var. parthneion and dipping into 25 ㎎ㆍL⁻¹ diniconazole solutions or drench of 25 ㎎ㆍL⁻¹ ancymidol in L. dauricum can be useful to produce the mini-potted plants.
