Abstract

To investigate the effects of floral preservatives on vase life and sugar content during flower senescence of cut lilies, Lilium Oriental hybrid 'Casa Blanca' flowers were treated with various chemical holding solutions. The holding solution containing 3% sucrose + 200 mg.L$^{-1}$ HQC + 50 mg.L$^{-1}$ AgNO$_{3}$ + 25 mg.L$^{-1}$ GA$_{3}$ or 50% soda pop (cider) + 50% tap water + 40 mg.L$^{-1}$ NaOCl + 25 mg.L$^{-1}$ GA$_{3}$ significantly increased vase life, fresh weight, flower diameter of cut flowers as compared with the control (distilled water). These treatments maintained high water balance and high chlorophyll content as compared with the control during senescence of flowers. The holding solution containing 3% sucrose + 200 mg.L$^{-1}$ HQC + 50 mg.L$^{-1}$ AgNO$_{3}$ + 25 mg.L$^{-1}$ GA$_{3}$ maintained high levels of sucrose, glucose, fructose, and total sugar for a long time as compared with the control. These results indicate that vase life and carbohydrate supply have a strong correlation.

오리엔탈 백합 '카사블랑카' 절화에 여러 가지 보존용액을 처리한 후 절화수명과 수분 및 당 함량 변화 등을 조사하여 이들이 백합 절화의 수명에 어떠한 영향을 미치는가를 밝히고자 본 실험을 실시하였다. 보존용액 3% sucrose + 200mg.L$^{-1}$ HQC + 50mg.L$^{-1}$ AgNO$_{3}$ + 25mg.L$^{-1}$ GA$_{3}$ 처리와 50% soda pop(사이다) + 50% tap water + 40mg.L$^{-1}$ NaOCl + 25mg.L$^{-1}$ GA$_{3}$ 처리에서 증류수 대조구보다 수명이 3일 이상 연장되었고, 화경도 약 2cm 가량 커졌으며 생체중이 대조구보다 높게 유지되었다. 또한 대조구는 흡수량에서 증산량을 뺀 수분균형이 (-)값으로 일찍 떨어졌지만 보존용액처리구는 수분균형이 (+)상태로 오래 유지되었다. 또한 3% sucrose + 200mg.L$^{-1}$ HQC + 50mg.L$^{-1}$ AgNO$_{3}$ + 25mg.L$^{-1}$ GA$_{3}$ 처리는 sucrose, glucose, fructose의 함량 및 총당함량이 대조구보다 오랫동안 높게 유지되어 수명증가에 기여하였으며 엽록소의 소실이 적고 페놀함량이 낮아 잎의 황화가 상당히 지연되었다.
