| Research Abstract |
The crystal size distribution of xenon hydrate in water indicated that the smaller crystal was formed at the lower temperature and the higher xenon gas pressure. The best combination of temperature and xenon pressure was 1℃ and 1.0MPa under the examined conditions. The barley coleoptile cells preserved at the combination of 1℃ and 1.0MPa showed significantly higher viable ratio than those preserved under -20 degree C. This meant the preservation by generation of xenon hydrate could do damage control.
