초록
지속적으로 증가하는 식량 수요를 충족시키기 위해 작물 생산량의 확대가 요구되고 있는 실정이다. 따라서 많은 연구자들이 다양한 관점에서 곡물류 식용 작물의 수확량, 품질, 파종 시기, 환경 적응력 등을 향상시키기 위한 연구를 수행하고 있다.본 연구에서는 초미세버블이 보리종자의 발아에 미치는 영향에대해 살펴보았다. 증류수 내에 생성된 초미세버블의 평균 직경과 개체수는 각각 133 ㎚, 8.59✕108 particles/㎖였으며, 초미세버블 혼합 증류수는 일반 증류수에 비해 보리종자 발아율을향상시킬 수 있음을 확인하였다.
Abstract
For the last few decades, much research has been tried to improve crop’s characteristics such as crop yield, quality, seeding period and environmental adaptability. In this paper, the effect of nanobubbles on the germination rate of barley seed is experimentally investigated. The air nanobubble was generated in water by gas-liquid mixing method. The results were shown that the mean diameter and concentration of nanobubble fabricated in DI water are 133 ㎚ and 8.59✕108 particles/㎖, respectively. Also, the seed germination rate for the nanobubble water was approximately 40 % higher than that of pure water. Key words - Nanobubble, Air gas, Barley seed, Hordeum vulgare L., Germination test
