국산 안개초 ‘Dream Song’ 가을~초겨울 절화 재배시 개화 촉진 및 절화 생산성 향상에 적절한 광원 선발을 위해 전조 광원별 생육 및 개화특성을 조사하였다. 백열등의 광질은 청색, 적색 및 원적외선 파장 모두 높고 고압나트륨등(HPS)은 적색 파장이 약간 높았으며, LED는 청색이 적색 파장보다 높았고 삼파장등은 청색과 적색 파장이 낮게 조사되었다. 주간(13:00)과 야간(전조 1시간 후, 23시)에 측정한 엽록소 형광 반응은 광원별로 차이가 없었다. 백열등과 고압나트륨등이 생육 진전이 빨라 출뢰 및 개화가 촉진되었으며, 화경장과 절화장이 길고 분지수와 개화율이 높아 절화량도 많았다. LED 전조는 개화 촉진 효과는 적었으나 분지수가 향상되었다. 따라서 경영비를 고려한 국산 안개초 ‘Dream Song’ 전조 재배 시 광원은 백열등이 적정하다고 생각된다.
The aim of this study was to investigate the effects of lighting sources on growth and flowering characteristics of the domestically bred Gypsophila paniculata ‘Dream Song’ to enable the grower to select a suitable supplemental lighting source for cultivation from autumn to early winter. The light quality of incandescent lamps was high in both blue and red and far-red wavelengths, and that in high pressure sodium (HPS) lamps was slightly higher in red wavelengths. A light-emitting diode (LED) had more blue than red wavelengths; whereas, three-wave fluorescent lamps had generally lower blue and red wavelengths. Our results showed that supplemental lighting sources did not affect chlorophyll fluorescence (ratio of variable fluorescence to maximum fluorescence). Lighting with incandescent or HPS lamps promoted growth, floral budding, and flowering, increased flower stalk and cut-flower length, and yielded higher numbers of total axillary buds, flowering percentages, and marketable yields. LEDs were less effective in promoting flowering, but produced a higher total number of axillary branches; therefore considering the cost, it was believed that incandescent lamps were a suitable supplemental lighting source for ‘Dream Song’ cultivation in autumn and early winter.
