Abstract

The effects of supplemental LED lightings on fruit quality and yield of two strawberry (Fragaria ${\times}$ ananassa) cultivars 'Daewang' and 'Seolhyang' were determined when blue (441 nm), red (659 nm) and mixed (blue:red = 3:7) LED lights were each supplied daily from 17:00 to 23:00 h, throughout growth period (from Nov. 10 to Mar. 20), with light intensity being adjusted to $75{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$. Incandescent bulbs, which are usually supplemented for winter strawberry cultivation, was used as a control. In both cultivars, blue LED increased yield, and all three types of LEDs enhanced fruit hardness and SSC, while acidity was highest in red LED. Anthocyanin contents in fruit were significantly increased by both blue and mixed LED lightings in 'Daewang', while in 'Seolhyang' only by the blue LED, compared to the incandescent bulb control. Blue and mixed LED lights enhanced glucose contents in 'Daewang' fruit, while did the mixed LED light in'Seolhyang' fruit. As for fruit organic acids, red LED significantly increased malic and oxalic acid contents in 'Daewang' and 'Seolhyang', respectively. In 'Daewang', fruit phenolic compounds contents were significantly higher in red LED or incandescent bulb control than other LED treatments, while in 'Seolhyang' seemed to be highest in the incandescent bulb control. Considering its positive effect on yield and fruit quality, blue LED could be a potential supplemental lighting source for strawberry cultivation winter season.

LED 보광 재배에 따른 딸기 '대왕'과 '설향' 품종의 과실품질과 생산량을 확인하기 위하여 11월 10일부터 3월 20일까지의 생육기간 동안 각각의 LED 광인 청색, 적색 그리고 혼합(청색:적색 = 3:7) 광을 17시부터 23시까지 $75{\pm}5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$의 광량으로 조절하여 전조하였다. 겨울철 딸기 전조재배에 주로 이용되고 있는 백열등을 대조구로 사용하였다. 딸기 두 품종에 있어, 생산량은 청색 LED 광에서 증가하였고, 과실 경도와 당 함량은 3종류의 LED 광 모두에서 향상되었다. 반면에 산도는 적색 LED 광에서 가장 높았다. 과실의 안토시아닌 함량에 있어서 '대왕'은 청색과 혼합 LED 광에서 유의적으로 증가한 반면, '설향'은 혼합 LED에서 증가하였다. 적색 LED는 유기산에 있어 '대왕'과 '설향'과실에 각각 말산과 옥살산의 함량을 증가시켰다. '대왕' 과실의 페놀화합물 함량은 적색 LED와 대조구인 백열등이 다른 LED 광처리보다 유의적으로 높았으나, '설향' 과실은 대조구인 백열등에서 가장 높게 나타났다. 효과적인 생산량과 과실품질을 고려해 볼 때, 겨울철 딸기 재배에 있어 보조광원으로 청색 LED 광이 유리할 것이다.
