Abstract

This study was conducted to examine the effect of LED light quality and treatment time on the growth and flowering in potted plants of Impatiens (Impatiens hawkerihybrid). Plant height of Impatiens was enhanced under Blue light, regardless of treatment time. Root length and stem diameter of Impatiens were enhanced by Red light or Blue light. The number of internodes was not influenced by LED light quality. The number of branches of Impatiens was increased under Blue light, but treatment time did not result in statistically significant differences. Leaf area was increased by all LED lights in Impatiens. The number of flower buds and open flowers was decreased by LED light, but days to flowering were reduced by Red light in Impatiens. Chlorophyll and anthocyanin content were not significantly affected by LED light, but anthocyanin content tended to increase by Blue light for 4 h after sunset. Fresh and dry weights were enhanced by Blue light in Impatiens.

본 실험은 임파첸스 분화식물의 생장과 개화에 LED 광질과 효과 적정 처리 시간을 구명하기 위해 수행되었다. 임파첸스의 초장은 2.50cm로 청색광에 의해 촉진되었으며 대조구에 비해 0.6cm의 차이를 보였다. 절간수, 뿌리길이, 분지수, 직경은 보광시간이나 광질에 영향을 받지 않았다. 엽면적은 412.81$cm^2$의 대조구에 비해 광질처리 시 626.64~784.53$cm^2$로 증가하였다. 광질처리에 의해 화아수와 개화수는 감소하는 경향을 보였다. 그러나 개화소요일수는 광질처리에 의해 단축되어 개화를 촉진하였으며 적색광에서 좋았다. 엽록소 함량은 광질처리에 의해 크게 영향을 받지 않았으나, 안토시아닌 함량은 전반적으로 일몰 후 4시간의 청색광에서 증가하였다. 광질처리는 청색광 처리에서 생체중과 건물중이 향상되었다.
