Abstract
This experiment was conducted to improve germination rate of the seed treated durationof storage and GA3 in Celosia argentea. With the seed directly after harvest, as increasingconcentration of GA3, ranged from 50ppm to 200ppm, and dipping hour, ranged from 6 to24 hour, the rate of germination was also increased. The germination of seed dipping in200ppm GA3 for 24 hours was the highest with 52% compared to the control with 12%. Asincreasing storage duration in 22± 2℃, ranged from 2 weeks to 12 weeks, the rate ofgermination was also increased showing 84% at 12 week. However, the rate of germinationwas not increased with the storage of 5℃, 0℃, and -70℃. With the seed storage 16 weeks in22± 2℃after harvest, the rate of germination was 84%. The rate of germination wasincreased 94% to 99% by the GA3 concentration, ranged from 50ppm to 400ppm, anddipping hour, ranged from 6 to 24 hour,. The germination was finished 4 days after sowing.
