The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [3] If intracellular ice forms, it could be lethal to the plant when adhesion between cellular membranes and walls occur. The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4]
Freezing cold weather sucks the life from just about everything — plants included. When the temperature needles to a freezing 32 degrees, most outdoor plants will survive the coastal Lowcountry ...
