Abstract
無極性ガスを利用した保存法のカーネーション切り花に対する適用性を検討するために, 切り花の品質に関係深い内部の水に対して無極性ガスが与える影響を明らかにすることを目的とした。水の状態は, 中性子イメージングによる水分量の分析と, <sup>1</sup>H-NMRによる縦緩和時間T<sub>1</sub>測定による水の動的状態から評価した。それらの結果から, 無極性ガスであるキセノンによる処理は, 切り花の吸水能力を維持することと同時に, 切り花内部の水移動を妨げ, 脱水を防ぐことが示唆された。特に, 0.7MPaでのキセノン処理を行った切り花子房部の縦緩和時間は, 処理後約24時間にわたり実験初期とほぼ同じレベルにあり, 水の動的状態が保持された。
In order to estimate the preservation method of cut carnation flowers by applying non-polar gas, the effect of Xe gas on the water in cut carnations was examined. The distribution of water concentration in cut carnations was given as gray scale images through neutron radiography and the mobility of water molecules was estimated by T<sub>1</sub> relaxation time of protons. The application of Xenon to cut flowers was found to maintain the water uptake activity and at the same time to prevent water loss. When 0.7MPa of Xe gas was applied, an appreciable change in T<sub>1</sub> relaxation time of water in ovaries was not observed over the first 24 hours. This suggested that the dynamic state of water in ovaries was held nearly constant by Xe-treatment.
