수출 절화 국화의 전처리제 처리가 개화지연에 미치는 효과를 알아보고자 수행하였다. 개화단계는 ‘백마’의 경우 GA4+7+BA 100mg/L 처리와 1-MCP 0.05g/㎥ 처리시, ‘백선’의 경우는 BA 25mg/L 처리시 대조구에 비해 개화가 지연되는 효과를 나타내었다. 꽃크기는 ‘백마’와 ‘백선’ 모두 1-MCP 0.05g/㎥ 처리 시 꽃크기 변화가 작게 나타났다. 화색변화는 ‘백마’의 경우 GA4+7+BA 100mg/L 처리와 1-MCP 0.05g/㎥ 처리 시, ‘백선’의 경우는 BA 25mg/L 처리시 대조구에 비해 꽃봉오리 화색변화가 지연되었다.

The effects of pre-treatments by plants growth substances and functional substances on vase life and physiological character of cut Lillium oriental hybrid 'Siberia' and Lillium asiatic hybrid 'Dream Land' were studied. For Lilium oriental hybrid Siberia, the vase life of 1st floret was extended by dip treated with Promalin and spray treated with Dan-solution Ⅱ(Nano colloidal Ag+ ion + Chitosan) and the vase life of 2nd floret was effected by dip treated with Promalin and Dan-solution Ⅱ. In case Lilium asiatic hybrid Dream Land, the vase life of 1st floret was extended by spray treated with Promalin and Dan-solution Ⅱ. The vase life of 2nd floret was increased by dip and spray treated with Promalin and by spray treated with Dan-solution Ⅱ. Water uptake of Siberiawas increased by all pre-treatment but wasn't showed significance. Also water uptake of Dream Land was increased by spray treated with Dan-solution Ⅱ. In case Siberia, fresh weight was increased with Dan-solution Ⅱ and was increased by dip treated with Promalin and by spray treated with Dan-solution Ⅱ in Dream Land. The amount of ethylene production of Siberia wasn't showed significance in all pre-treatment but when floret of Dream Land was treated with Dan-solution Ⅱ, the peak point was showed in 1st day. The respiration rate was showed climacteric rise type by all pre-treatment in Siberia and Dream Landand the peak point was a little decreased by Dan-solution Ⅱ treatment. Sugar contents were remarkably promoted in petal when florets of Siberia was treated with Distilled water and Dan-solution Ⅱ treatments, but were decreased in leaf and ovary. In case Dream Land, glucose content was not showed changes in leaf but fructose content was decreased. Also sugar content of ovary and petal were showed tendency such as Siberia.
