Tubers(4-5cm diameter) of Zantedeschia 'Black Magic' were used to study the induction of flowering in GA<sub>3</sub> soaking times and concentration. The GA<sub>3</sub> soaking were 10 seconds and 30 minutes at the GA<sub>3</sub> concentrations of 50, 100, 250, and 500 mg·L<sup>1</sup>. The time to emergence in GA<sub>3</sub> treatment were 1.1~4.0 days shorter than control Growth characteristics were good in GA<sub>3</sub> treatment but that was no significance in GA<sub>3</sub> soaking time and concentration. When GA<sub>3</sub> soaking time and concentration were increased, days to flowering was shorter, but flower stalk length, flower stalk width, flower length, flower width were no difference. The number of flower per tuber was most as 4.0~4.3 in 250~500 mg·L<sup>1</sup> GA<sub>3</sub> concentration and that was about 2 times compared to control. The normal flower ratio and bulb enlargement were similar compared with GA<sub>3</sub> soaking time and concentration. GA<sub>3</sub> 250~500 mg·L<sup>1</sup> treatment is necessary for improvement of number of flowers per bulb.
