Locally heated dormant cambium can re-initiate cell production independently of new shoot growth in deciduous conifers (Larix kaempferi)

The results suggest that in deciduous conifer trees, cambial dormancy is imposed by low air temperature during mid-late winter, and a rise in temperature directly triggers cambial reactivation independently of new shoot growth in spring. However, continued cell division in the reactivated cambium and xylem differentiation of cambial derivatives might require certain factors, which originate from elongating shoots, besides starch stored in phloem.
