Effect of Storage Duration and GA₃ of Seed Germination of Celosia argentea

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