Oddvar SkreAbstract
Frost damages may take place by rapid intracellular freezing or by extracellular ice formation and cell dehydration. The damages are measured visually or by electroconductivity measurements.The first hardeing stage is induced by short days and light, and is related to dormancy induction. The second stage is induced by low temperatures (-2-5 C). During this and the third stage, water binding forms of proteins and sugars are formed, and the membranes are re-structured in order to better withstand dehydration.Potassium prevents frost damages by increasing the resistance against dehydration while nitrogen and phosphorus in high concentrations are extending the growth period and exhaust carbohydrate reserves, making the plants more exposed to frost damages.
