Responses of cambium to warming were recorded three times (December 14–27, 1990, January 18–February 3 and February 27–March 13, 1991) on 14-year-old  Cryptomeria japonica  D. Don and four times (December 12–26, 1990, January 18–February 2, February 26–March 12 and March 28–April 13, 1991) on 27-year-old  Larix leptolepis  Gord., during a period of winter cambial dormancy. Stem surfaces at breast height, mid-tree height and the crown base were warmed to 25–30 °C for 2 weeks. After heat treatment, cambia in the treated regions and in untreated regions 1 m above each treated area were examined by optical and transmission electron microscopy (TEM). In  C. japonica , heat treatment often resulted in cambial reactivation in the treated regions, and this response to heat gradually increased as the dormant season passed from winter to spring. Conversely, in  L. leptolepis , no cell division was observed in the cambial region of warmed stems until natural resumption of cambial activity, which occurred after bud break.
