Abstract

The aim of this study was to determine the effect of day-length extension treatment using LED lighting (blue, green, red, or 3 mixed) on vegetative growth and flowering of freesia 'Yvonne', in comparison to that using glow lamps and metal halide lamps. Lighting treatments were imposed from 5 PM to 8 PM for 150 days from after flower bud differentiation to flowering end. For the period from leaf emergence to floral bud formation, no light source affected plant height but the number of leaves was decreased by the metal halide lamp. The highest SPAD value in the flower bud developing period occurred in the metal halide lamp treatment. The time of flowering was advanced by blue or green LED treatment compared to the no lighting control. The green LED lighting advanced flowering by 6 and 8 days compared to no lighting and metal halide lamp treatment, respectively. The blooming period tended to be shortened by the red LED treatment. As for the flower characteristics of 'Yvonne', floret length and width, and the weight of cut flowers were highest in the metal halide lamp treatment. Red LED decreased corm width and weight of 'Yvonne' while glow lamp decreased height and weight. Starch contents in corm were not influenced by the lighting source. Our results indicate that the green LED lighting advanced the time of flowering and the metal halide lamp was good for cut-flower quality.

본 연구는 프리지아 '이본느'를 가지고 매일 오후 5시에서 8시까지 150일 동안 LED(청색, 녹색, 적색, 청색:녹색:적색 혼합)광과 백열등, 메탈할라이드등으로 보광을 함으로써, 꽃눈분화 이후부터 개화가 완전히 종료될 때까지 광질에 따른 장일처리가 프리지아의 생육 및 개화에 미치는 영향을 알아보기 위하여 수행되었다. 엽분열기부터 화뢰형성기까지 초장은 광원별 장일처리에 의해 큰 변화는 없었고 엽수는 메탈할라이드등 처리에서 감소하는 경향이었으나 화뢰 발달기 때 엽 내 엽록소 함량은 메탈할라이드등에서 가장 높았다. LED 청색광과 녹색광에서 개화기가 빨랐는데 특히 녹색광 처리에서 가장 빨라 무처리와 메탈할라이드등에 비해 6-8일 정도 단축되었다. 포장 내 개화기간은 LED 적색광에서 가장 짧아 일시 수확에는 효과적이었다. 메탈할라이드 등에서 절화중, 소화의 길이와 폭 등 절화특성이 우수하였다. 구근의 특성을 조사한 결과 LED 적색광에서는 구폭과 구중이, 백열등 처리에서는 구고와 구중이 감소하였고, 구근 내 전분함량은 모든 시험구 사이에 특별한 차이가 없었다. 결과적으로 개화촉진은 LED 녹색등에서 효과적이었고 개화품질은 메탈할라이드등 처리에서 우수하였다.
