The amount of sold cut carnations in the wholesale market ranked second in 1999. But the demand of cut carnations shows a large seasonal change. Thus the longevity of vase life of cut carnations is a very important problem. Flowers are exposed to water stress, caused by increased water loss and limited water uptake, immediately after picking. Water stress has been shown to accelerate senescence and to reduce the longevity of cut flowers. Thus water status in plant tissue is important to the maintenance of the quality of cut flowers. Most postharvest handling of cut carnations depends on chemicals that is the inhibitor of ethylene action in plant tissue. Attempts of postharvest handling by gene recombination are also reported. However it is supposed that those methods have a negative effect on the environment or human life. Thus the establishment of a safer and more effective preservation method is important. The authors have studied a preservation method for cut carnation flowers that uses non-polar gas. The dissolution of xenon gas, a non-polar gas, produces a change in water structure to a clathrate-like structure and yields an increase in the number of hydrogen-bonded water molecules. Since the viscosity of water is closely related to intermolecular potential energy, the increase in hydrogen-bonded water molecules could be interpreted as an increase in water viscosity. This increase in water viscosity could reduce the mobility of intracellular water. Water in this state is calledstructured, andstructured wateris the term used to describe water with a large population of hydrogen-bound water molecules. Structured water is supposed to effect the water stress of cut flowers, because it would be closely related to the intermolecular potential of plants. The objective of this study is to investigate the effect of structured water on the intermolecular water of cut carnations, and to derive the possibility of a new preservation method by using non-polar gas. Chapter 2 Carnation flowers (Dianthus caryophyllus L. cv. Francesco) were obtained from a commercial grower in Chiba prefecture and transported in a dry state within 24h to the University of Tokyo. Upon arrival, the stems was trimmed under water, and the flowers were placed in distilled water. Flowers were kept in a constant temperature room at 293K in darkness for 24h. Samples at the same stage of opening were then chosen and the stems were recut to a length of 10cm. After recutting, samples were placed in a flask with distilled water. Among the non-polar gases that can form structured water, inert gases are the most suitable since they can be expected not to cause biochemical changes in cells because of their low chemical reactivity. Xenon gas was selected to form structured water because it is the most soluble of the inert gases. That is, xenon more readily forms structured water than do the other inert gases.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3641"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
