종자 새싹에 대한 소비자의 관심이 세계적으로 증가하면서 영양학적으로 가능성 있는 새싹 잎에 대한 연구가 필요한 실정이다. 흰색(WRM), 청색(BRM) 및 적색(RRM)의 광원에 따른 홍화새싹 성분과 비타민 C 함량을 연구하였다. 대략적인 수분, 회분 및 총 지방의 함량은 BRM 또는 WRM 보다는 RRM 광원으로 재배한 홍화 새싹에서, 조단백질 함량은 BRM이나 RRM 보다는 WRM으로 재배한 홍화 새싹에서 높게 측정되었다. 클로로필 함량은 WRM이나 BRM 보다는 RRM에서 재배한 홍화새싹이 높게 측정되었으며, 비타민 C 함량은 WRM, BRM, 그리고 RRM에서 재배한 홍화새싹에서 각각 157.57, 164.64, 그리고 158.10 mg%이었다. 본 연구 결과는 다양한 광원에서 홍화 새싹을 재배하는 것이 홍화 새싹의 영양학적 품질을 향상시키는 효과적인 방법이라는 것을 보여주었다.

Background and objective: The nanobubbles remain stable in water, and it increased dissolved oxygen (DO) in the water that promotes the seed germination and the plant growth. We evaluated the seed germination and growth of sprouts (radish, wheat, and barley) and leafy vegetables (red mustard and pak choi) when irrigated with various DO of nanobubble water (NB). Methods: The oxygen NB was generated by surface friction and treated in 4 levels: NB 0% (control, DO 9.21 mg·L^-1), NB 20% (DO 15.40 mg·L^-1), NB 33% (DO 20.93 mg·L^-1), and NB 100% (DO 39.29 mg·L^-1). Results: The root length of radish and wheat increased more in NB 33% than the control plot. The fresh weight increased in NB 33% compared to the control plot in radish and wheat, and both fresh and dry weight increased more in NB 20%, NB 33%, and NB 100% than the control plot of barley. The leaf length and width of red mustard decreased more in NB 33% and NB 100% than the control plot and NB 20%, which indicated the leaf compactness. The fresh and dry weight of shoot and root increased more in NB 100% than the control plot in red mustard. In pak choi, the shoot fresh weight increased more in NB 100% than the control plot. In leafy vegetables, the germination rate of red mustard in NB 100% was higher than the control plot, however, it was not significantly different between oxygen NB plots in sprout vegetables. Conclusion: The results showed that the root growth and biomass increased after applying NB 33% in sprout vegetables. The leaf growth properties as the number of leaves and leaf size were not significantly different or decreased in NB treatments compared to control plots, but NB 100% (DO 39.29 mg·L^-1) effectively increased the root growth and plant biomass in leafy vegetables.
