Abstract

This research was carried out to investigate the effect of supplemental lighting on stable productivity of paprika (Capsicum annuum L.) during low radiation period of winter season. The supplemental lighting sources used in this research were high pressure sodium (HPS) and lighting emitting plasma (LEP). Photosynthetic photon flux density (PPFD) emitted from both lamps decreased as vertical distance from lamp increased. The PPFD of LEP lamps were twice more than that of the HPS lamp per unit distance, but the rate of decreased PPFD of t he LEP per unit distance was higher than that of HPS lamp. And different degrees of PPFD between HPS and LEP lamps by horizontal distance had a smaller degree of difference than by vertical distance at the 100 cm away point. As daily average PPFD measured at the top of the plant under the supplemental lighting during January, the supplemental lighting significantly increased radiation. Radiation of HPS and LEP lighting was 137% and 315% higher than control (without supplemental lighting = sunlight). Air temperature in the top of the plant was not significant different among treatments. HPS and LEP lighting had no effect on increase of flower settings. Leaf length and width with LEP lighting was the longest, photosynthetic was higher than those of other treatments. Supplemental lighting treatments significant increased fruit length and diameter. Especially LEP lighting treatment had a greater effect on fruit length and diameter. In conclusion, LEP lighting treatment during low radiation period greatly affected growth and production of paprika. Further research will be required for the suitable application of LEP lighting in paprika production.

본 연구는 겨울철 약광기 파프리카의 안정적 생산을 위한 보광 효과를 구명하고자 수행하였다. 보광 램프로는 고압나트륨(high pressure sodium, HPS)과 Lighting Emitting Plasma (LEP)를 이용하였다. 두 광원 램프로부터 수직으로 떨어진 거리가 증가함에 따라 광량자속밀도(PPFD)는 감소하였다. 동일 거리별 PPFD는 LEP 램프에서 HPS 램프보다 2배 정도 높았지만, 거리 증가에 따른 감소율은 HPS 램프에 비해 LEP 램프에서 상당히 높았다. 수직 거리 100cm 지점에서 횡으로의 거리에 따른 두 광원 간 PPFD 차이는 수직 거리에 따른 차이보다 적었다. 1월 동안 보광 처리에 따른 식물체 정단부의 PPFD 측정 결과, 무처리구에 비해 HPS 보광 처리구에서는 137%, LEP 보광 처리구에서는 315%로 보광에 따른 유효 광량은 뚜렷하게 증가하였다. 그러나 식물체 정단부의 온도는 큰 차이를 나타내지 않았다. 보광 처리 20주째까지 파프리카의 착화를 증가시키는 데에 효과가 나타나지 않았다. 엽장과 엽폭은 LEP 처리구에서 가장 길었고 광합성률도 가장 높았다. 수확과실의 무게는 무처리구에 비해 보광 처리구들에서 무거웠고, LEP 보광 처리는 과장과 과고를 증가시키는 데에 효과를 나타내었다. 3회에 걸쳐 수확된 과실수는 HPS 보광 처리구나 무처리구에 비해 LEP 보광 처리구에서 많았다. 따라서 겨울철 약광기 파프리카의 생육 및 생산성을 증대시키는 데에는 LEP 광원을 이용한 보광 효과가 인정되나, 차후 현장에 적합한 LEP 광원의 활용 방법에 대한 연구가 필요할 것으로 생각된다.
