What will occur within a tree during a freezing event?

?

slide-5
SLIDE 5

How can living cells survive to freezing events ? How can the water transport system be still functional after one or more freeze-thaw cycles?

?

What will occur within a tree during a freezing event? Focus on trunk or branches….

SLIDE 6

During a freeze-thaw cycle… Let’s have a look inside the tree….

?

And let’s listen to the tree…!!
