Fagykár

Fagykár refers to damage caused by frost to plants. This phenomenon occurs when water within plant tissues freezes, expands, and ruptures cell walls. The extent of fagykár depends on several factors, including the plant species' tolerance to cold, the severity and duration of the frost, and the plant's physiological state at the time of the frost event.

Different parts of a plant can be affected. Buds, flowers, young leaves, and fruits are generally more susceptible to frost damage than mature tissues or woody stems. Symptoms of fagykár can range from mild discoloration, such as browning or blackening of leaf edges, to complete wilting and death of plant parts. In severe cases, the entire plant may succumb.

Fagykár can have significant economic consequences, particularly in agriculture and horticulture. Fruit crops, vegetables, and ornamental plants are vulnerable, and frost events can lead to substantial yield losses and reduced market value. Growers employ various methods to mitigate fagykár, such as selecting frost-resistant varieties, using protective covers, or employing irrigation techniques that release latent heat during freezing. Understanding the conditions that lead to fagykár and the plant's response is crucial for effective prevention and management.
