Frost tolerance refers to the ability of plants, animals, and other organisms to withstand cold temperatures without suffering damage. This adaptation is crucial for survival in environments where temperatures can drop below freezing. Frost-tolerant species often have special mechanisms, such as antifreeze proteins or altered cell structures, that help them endure icy conditions. In agriculture, understanding frost tolerance is important for crop management. Farmers may select frost-tolerant crops to ensure better yields in cooler climates. Additionally, knowledge of frost tolerance can guide planting schedules and protect sensitive plants during unexpected cold snaps, ultimately supporting food security and ecosystem health.
