The changes in the amount and distribution of water in the lumina of the current years earlywood vessels during the course of the freezing and thawing were visualized by cryoscanning electron microscopy. When samples were frozen, most of the current years earlywood vessels were filled with water. After the subsequent thawing, the percentage of cavitated current-year earlywood vessels gradually increased with time. All of the current years earlywood vessels were cavitated within 24 h, and only limited amounts of water remained in the lumina of earlywood vessels. Similar cavitation of earlywood vessels was observed after thawing of frozen, excised stem pieces. In contrast, many vessels of the current years latewood retained water in the lumina during freezing and thawing. These observations indicate that the cavitation of the current years earlywood vessels is not produced during freezing but progresses during rewarming after freezing in F. mandshurica var japonica.
