Variety traits

Cold tolerance of carrots

Daucus carota L.

The ability of the crop to germinate at low temperatures, for seedlings to withstand spring frosts, and to resist premature bolting when exposed to cold.

In the reference 7 varieties crop Carrot, where this is mentioned in the description.

Carrots are considered a relatively cold-tolerant crop, with seeds beginning to germinate at soil temperatures of +4...+6 °C. Young seedlings can withstand short-term spring frosts down to -3...-5 °C without plant mortality.

Cold tolerance is closely linked to the risk of premature flowering stem formation. Prolonged exposure to low positive temperatures, especially during the 5–8 leaf stage, induces bolting; therefore, breeding programs are focused on developing genotypes resistant to this transition.

Cold tolerance in breeding is assessed by growing plants under stress conditions and performing laboratory analysis of germination at low temperatures. Although the crop is adapted to cold, optimal temperatures for root development and leaf growth are significantly higher, ranging from +18...+25 °C.
