Abstract

Plant factory can control artificially the environments for crop cultivation, so they can produce high quality agricultural products all year round. This study was carried to select suitable kohlrabi cultivar for hydroponics in a closed-type plant factory system. We used three cultivars of red kohlrabi, ‘Asac kohl’, ‘Kolibri’, and ‘Purple king’ as plant materials. The artificial light source was LED light, light intensity and photoperiod were 249μmol·m-2·s-1 and 12/12 hours (day/night period), respectively. Hydroponic cultivation type was used circulating deep flow technique. At 43 days after transplanting, fresh weight of whole plant and tuber and leaf area were not significantly different among cultivars. Shoot dry weight and tuber dry weight were highest in ‘Asac kohl’ cultivar, and number of leaves was highest in ‘Purple king’ cultivar. Sugar content and yield were highest in ‘Asac kohl’ cultivar. Considering the growth and marketable yields, ‘Asac kohl’ was the optimal kohlrabi cultivar for hydroponic cultivation in a closedtype plant factory system.

식물공장에서는 작물에 필요한 재배환경을 인위적을 조절하여 고품질 농산물에 대한 연중 계획생산이 가능하 다. 본 연구는 완전제어형 식물공장 재배에 적합한 콜라 비 품종을 선발하고자 실시하였다. 실험은 완전제어형 식물공장에서 수행하였고, 식물재료는 적색의 콜라비 품종 인 ‘아삭콜’, ‘콜리브리’와 ‘퍼플킹’ 품종을 사용하였다. 인 공광원은 LED광이었으며, 광도와 일장은 각각 249μmol·m·2·s-1, 12/12시간(밤/낮)이었다. 순환식 담액수 경방식으로, 정식 후 57일까지 재배하였다. 정식 후 43 일째에 전체 생체중과 괴경의 생체중 및 엽면적은 품종 간에 유의적인 차이를 보이지 않았다. 건물중과 괴경은 ‘아삭콜’ 품종이 가장 높게 나타났으며, 엽수는 ‘퍼플킹’ 품종이 가장 많았다. 당도와 수량는 ‘아삭콜’ 품종이 가 장 높았다. 생육과 상품수량을 고려해 볼때, 완전제어형 식물공장에 적합한 콜라비 품종은 ‘아삭콜’ 이었다.
