vernalization
Jarowization, vernalization, vernalization - biochemical processes occurring under the influence of low temperatures in winter and perennial plants, affecting their blooming. These plants can grow only vegetatively, without creating any flowers at all. Only the period of cooling causes the plant to pass into the generative phase. The length required to induce flowering of the vernalization period depends on the species of the plant. The temperature of the cooling period is usually 0-10 ° C.
