Abstract

In order to optimization germination condition of broccoli, we carried out germination ratio experiment under soaking time, soaking temperature, oxygen concentration. The germination ratio results 98.5% following as soaking water having 10 ppm DO(demanded oxygen) during 4 hr at $20{\sim}30^{\circ}C$. The result of provide the dissolved oxygen water, when the concentration of oxygen water were 7, 12 ppm, germination ratio were observed about 76%, 92%. Also, we showed the growth rate of 2 times in 12 ppm compared with 7 ppm. Consequently, germination ratio of broccoli increased cultivation condition at soaking water having high concentration oxygen more than supply to oxygen water of high concentration.

본 연구에서는 다양한 침지조건에서의 브로콜리 최적 발아조건을 찾기 위한 실험을 수행하였다. 그 결과 4시간동안 $20{\sim}30^{\circ}C$에서 10 ppm 이상의 용존산소를 공급하면서 침지하였을 경우 약 98.5%의 발아율을 보였다. 산소수의 영향을 관찰한 결과 7, 12 ppm에서 각각 76%, 92%의 발아율을 보였으며, 12 ppm 산소수 공급조건에서 7 ppm에 비해 2배 이상의 생장률을 확인할 수 있었다. 결과적으로 브로콜리의 발아율은 재배 시 산소수의 공급보다 침지 시 산소수를 공급할 경우 증가하는 것으로 판단된다.
