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.

상사화와 석산 절화에 대한 화학약품 및 물리적 처리에 따른 화경 끝의 갈라짐과 절화수명을 조사하였다 .상사화와 석산의 절화를 채화직후 4 mM STS 용액에 30분간 꽃아 둔 결과 화경 갈라짐이 일어나지 않았다. 상사화의 절화수명 연장을 위해서는 4 mM STS 용액으로 30분 정도 전처리를 한 다음 5~10% Sucrose + 150 ppm 8-HQS + 4 ppm Rox의 보존용액에 꽃는 게 효율적인 것으로 나타났다. 열탕처리는 상사화의 경우 15-25초, 석산은 5-10초 처리가 화경의 갈라짐 방지와 절화수명 연장에 효과적인 것으로 나타났다. 화경 절단부위를 불에 태우는 시간은 상사화의 경우 10-30초, 석산은 10-15초 처리시에 화경갈라짐 방지와 절화수명 연장에 효과적이었다. 화경의 절단은 수평으로 자른 것에 비해 45˚로 경사지게 잘랐을 경우에 절화수명이 연장되었다. 절화 화경에 대한 밴딩처리는 화경갈라짐 현상 방지 및 절화수명연장에 효과가 있었다.

The opening process of cut calla flower was faster at 30 t than at lower temperatures as it could be expected from its tropical origin. Gibberellin enhanced the flower opening, however, it also speeded up senescent. Silver thiosulfate was effective in prolonging the vase life of the cut calla flower. Silver thiosulfate reduced ethylene generation by the flower and inhibited microbial growth in the flower stalk. Reduction in ethylene generation and inhibition of microbial growth is thought to be responsible for the extension of the vase life of cut calla flowers by silver thiosulfate.
