Antifrost

The protective effect of Antifrost by temperatures below freezing, is achieved mainly due reducing the respiration and transpiration of the plants. Moreover the balanced composition of Antifrost depress the freezing point of plant fluids and provide greater protection against frost.

Way of action:

Balanced concentrations of potassium and phosphorus have proven to be an advantage in frost and winter tolerance. Phosphorus is known to improve acclimatization of plants, is important for cell division and therefore it helps the recovery of tissue after freezing.

Potassium boosts photosynthesis, impairs the formation of toxic reactive oxygen species at low temperature and maintains cell hydration under freezing stress. High concentrations of K+ protect against freezing by lowering the freezing point of the plant’s cell solution.

Furthermore, an adapted cytosol K+ concentration is also essential for enzyme activities that are involved in regulating frost resistance.

The effects of the high K+ content of the cell in increasing frost tolerance have also been related to regulation of osmotic and water potential of the cell sap and reduction of electrolyte leakage caused by chilling temperature. Also the included organic polyols help as osmo-protectors in the same manner.

Micronutrients improve crop tolerance to frost damage by promoting photosynthesis, antioxidant enzyme activity, membrane stability and cell hydration.
