Abstract

This study was conducted to find out the effect of supplemental lighting on the photosynthesis and cut flower yield of Gerbera hybrida 'Sunny Lemon' in order to improve the winter season productivity. Cut flower yield and photosynthesis were respectively increased 48-58% and 15-200% as affected by supplemental lighting sources compared to the control. It seems that high pressure sodium lamp or metal halide lamp was the appropriate supplemental lighting lamp because those lamps provides higher photosynthetic rate and heating effect. Cut flower yield and quality tendes to increased although higher electricity consumption is to required. In particular, loss factors such as installation expenses and electricity charge were greater than profit factors such as increasing yield and heating effect at over 30 kW $10\;a^{-1}$ treatments. It was recommended that the electricity consumption by 30kW $10\;a^{-1}$ with HPS or MH was promising cultural method to improve the higher productivity of Gerbera hybrida 'Sunny Lemon'.

거베라의 동계 약광기 생산성 향상을 위하여 보광처리가 광합성과 수량에 미치는 영향을 검토한 결과는 다음과 같다. 광원별 보광처리에 의해 절화수량은 48-58%, 광합성률은 15-200% 증가하였으며 특히 고압나트륨등과 메탈할라이드등이 광합성률이 높고 보광등의 발열로 인한 환경개선 효과가 높아 적합한 보광용 광원으로 나타났다. 한편 전력사용량이 증가할수록 무처리에 비해 수량이 증가하고 절화품질이 향상되는 경향이었으나 절화수량 증가와 난방효과와 같은 이익적인 요소에 비해 설치비용, 전기요금 등의 손실적인 요소들이 더 발생하여 $30kW{\cdot}10a^{-1}$ 수준의 보광이 적합한 보광시설 설치 기준으로 판단되었다.
