보존용액에 첨가된 ethionine이 절화장미 화판의 물리적 구조에 미치는 영향 = Effect of Ethionine Applied in the Preservative Solution on the Physical Structure of Petal of Cut Rose

다국어 초록 (Multilingual Abstract)

Effect of ethionine in the preservative solution on the thickening phenomenon of petal of cut rose 'Red Sandra' was investigated. According to the result of cross section's observation by microscope, plasmolysis was observed in petal cell of cut rose maintained in the distilled water but not in that of cut rose maintained in the preservative solution containing ethionine on 10 days after experiment. On 13 days after experiment, epidermal and mesopyll cells of petal of cut rose maintained in the distilled water showed a profound shrinkage whereas epidermal and vascular bundle tissue of cut rose maintained in the preservative solution showed a fairly normal condition. Therefore, it was found that thickening phenomenon of petal on the basis of visual observation during vaselife is not due to either the division of epidermal cells or production of secondary cell wall but tugor pressure according to maintenance of the membrane integrity.
