During which season do cambium cells slow their growth rate?

Cambium cells are responsible for the secondary growth of plants, contributing to the thickening of stems and roots. During winter, many plants enter a state of dormancy or significantly reduce their metabolic activities as a response to lower temperatures and reduced daylight. This change in environmental conditions leads to a slowdown in the activity of cambium cells.

In contrast, during spring and summer, cambium cells are active, contributing to rapid growth as plants take advantage of warmer temperatures and abundant sunlight. Fall can be a period of preparation for dormancy, but it’s the winter season when cambium cell activity is notably reduced due to the harsher environmental conditions. Therefore, it is during winter that cambium cells experience the lowest growth rates.
