Water ascension within tree Wood: Long dead cells: vessels of water transport system and living cells
What will occur within a tree during a freezing event? ?
What will occur within a tree during a freezing event? ? Focus on trunk or branches…. How can living cells survive to freezing events ? How can the water transport system be still functional after one or more freeze-thaw cycles?
