Abstract
Typical rose flowers, 'Red Corvette (red)', 'Nobless (pink)', 'Golden Metal (yellow)', and 'Rose Yumi (white)', were used as experimental materials to examine flower color changes as affected by pressing method and light treatment for four weeks and eight weeks by 2,000 lux fluorescent light at a 16 hours daylength. Pressing materials in silicagel mat resulted in the least change after pressing and light treatment for all kinds. On the contrary, an electric pressing device caused color to change to brown. Flower colors deteriorated the most by an electric pressing device made in Korea for pink rose; an electric pressing device made in Japan for white rose; and paper sheet made in Korea for red rose. The sequence of degree in severity of color change after pressing was pink, yellow, and white roses. Light treatment brought about the most extreme color change in yellow 'Nobless' rose, while other three cultivars were rather stable in change of color.
장미의 대표적인 화색인 적색 'Red Corvette', 분홍색 'Nobless'b, 황색 'Golden Metal' 및 백색 'Rose Yumi' 꽃을 재료로 건조방법에 따른 화색의 변화를 조사하고, 4주 및 8주간의 광처리(2,000lux, 16시간, 형광조명) 뒤의 화색 변화를 조사하였다. 모든 종류에서 실리카겔 매트로 압화 하는 처리구가 압화 당시와 광처리 후 화색변화가 가장 적었고, 전기압화기의 사용으로 꽃잎은 갈변화가 촉진되었다. 장미 적색은 한국산 시트지, 분홍색과 황색은 한국산 전기압화기, 장미 백색은 일본산 전기압화기 처리구가 화색의 변화가 가장 심하였다. 압화 당시 화색의 변화가 가장 컸던 것은 적색 장미였고, 그 다음이 분홍색, 황색, 백색 순이었다. 광처리에 의한 화색 변화정도가 가장 심했던 것은 황색 품종이었고, 다른 3종류는 다소 안정적이었다.
