Abstract

This study was conducted to examine the optimal environmental condition for promoting the growth of sowthistle as affected by light quality and photoperiod in a closed-type plant production system. Seeds were sown in 240-cell plug trays and then germinated for 3 days at a 24-hour photoperiod in a closed-type plant production system with LED lights (R:B:W = 8:1:1). Seedlings were transplanted and grown under 3 types of LED (R:B:W = 8:1:1, R:W = 3:7, or R:B = 8:2) and 4 photoperiods (24/0, 16/8, 8/16, or 4/20 hours) with $230{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ light intensity at a density of $20cm{\times}20 cm$. The experimental design was a randomized complete block design. Plants were cultured for 40 days un der the condition of $21{\pm}2^{\circ}C$ and $70{\pm}10%$ relative humidity after transplanting. Plants were fed with a recycling nutrient solution (pH 7.0 and EC $2.0dS{\cdot}m^{-1}$) contained in a deep floating tank. Fresh weight and dry weight of shoot or root, leaf length, and leaf area were the greatest in the photoperiod of 24/0 (light/dark) with RW LED. The highest number of leaves occurred in the photoperiod of 16/8 (light/dark) with RB LED, while the incidence of tip burn was higher in the photoperiod of 24/0 (light/dark) compared to the other treatments. Chlorophyll value was the highest in the 16/8 (light/dark) photoperiod and there was no significant difference by light quality. Chlorophyll fluorescence was the lowest in the photoperiod of 24/0 (light/dark) compared with other treatments. Therefore, in terms of economic feasibility and productivity for Ixeris dentata Nakai cultivation in a closed-type plant production system, the results obtained suggest that plants grew the best when kept in a photoperiod of 16/8 (light/dark) and light quality of combined LED RW (3:7).

본 연구는 밀폐형 식물생산시스템 내에서 광질과 광주기에 따른 씀바귀(Ixeris dentata Nakai)의 생육 증진을 위한 적정 생육환경 조건을 구명하고자 수행되었다. 씀바귀 종자는 240구 플러그 트레이에 파종하였고, 밀폐형 식물생산시스템에서 LED(R:B:W = 8:1:1)하에서 24시간 광주기로 3일간 발아 하였다. 묘는 $230{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$의 광도의 3종류의 광질(R:B:W = 8:1:1, R:W = 3:7, R:B = 8:2)과 4종류의 광주기[24/0, 16/8, 8/16, 4/20 (명기/암기)]하에서 $20cm{\times}20 cm$의 재식밀도로 난괴법으로 배치 하였다. 씀바귀는 정식 후 온도 $21{\pm}2^{\circ}C$, 상대습도 $70{\pm}10%$ 조건에서 40일 동안 재배 되었다. 관수는 담액식 양액 재순환 방식을 이용하였다(pH 7.0, EC $2.0dS{\cdot}m^{-1}$). 24/0(명기/암기)의 광주기 처리와 RW 광질 처리에서 지상부와 지하부의 생체중과 건물중, 엽장, 엽면적은 가장 우수했다. 16/8(명기/암기)의 광주기 처리와 RB 광질에서 엽수는 가장 많았으며, 잎끝마름 발생률은 24/0(명기/암기)의 광주기 처리에서 다른 처리보다 높게 나타났다. 엽록소 값은 16/8(명기/암기) 광주기 처리에서 가장 높았으며 광질에 따른 차이는 없었다. 엽록소형광은 24/0(명기/암기) 광주기 처리에서 다른 처리구에 비해 현저히 낮은 값을 보였다. 결과적으로, 밀폐형 식물공장 시스템 안에서 씀바귀 재배의 경제적인 실현가능성과 생산적인 측면에서 16/8(명기/암기) 광주기 처리, RW의 광질에서 씀바귀를 재배하는 것이 가장 효과적인 것으로 판단된다.
