Abstract

This study was conducted to investigate growth characteristics of paprika seedlings according to various qualities of LED light (red : blue = 10 : 0, red : blue = 8 : 2, red : blue = 2 : 8, white). Plant height and stem were significantly longer or thicker as red light ratio increased. Leaf area of paprika seedlings with red light was larger or no significant differences in a mixed light of red and blue. Dry weight of seedling was in the same with the result of leaf area. Seedlings with White light was significantly less than others in all characteristics. As red light ratio was increased, relative growth rate increased. As blue light ratio was increased, the net assimilation amount increased. Considering plant height, leaf area and production ability of dry matter per unit leaf area, the using mixed red and blue lights was suitable, especially at a mixed red : blue = 8 : 2.

본 연구는 파프리카 육묘 시 다양한 LED 광질(red:blue = 10:0, 8:2, 2:8, white)에 따른 생육변화에 대하여 구명하여 수경재배용 묘 생산을 위한 전용육묘장의 기반기술로 활용하고자 수행하였다. 초장과 줄기직경의 생육은 red 비율이 높을수록 유의하게 길거나 굵었고, 엽면적은 LED red:blue = 8:2에서 가장 넓었다. 건물 중량도 엽면적과 동일한 경향이었다. LED white에서는 모든 묘의 소질에서 다른 처리들보다 뚜렷하게 저조하였다. 상대생장률은 red 비율이 높을수록 높은 경향을 나타내었고 순동화율은 blue 비율이 높을수록 높은 경향을 나타내었다. 따라서 본 시험에서 LED를 활용한 파프리카 육묘 시 초장, 엽면적, 단위엽면적당 건물생산능력 등을 고려하였을 때 혼합광을 이용하는 것이 적합하고 특히, LED red:blue = 8:2가 가장 적합한 것으로 생각된다. 그리고 red와 blue 파장의 적절한 혼합 비율을 통해 파프리카 묘의 초장 및 절간장을 제어할 수 있을 것으로 생각된다.
