在自然环境条件下，耐寒性在时间上与针叶树和其他温带原生树种的枝条休眠有关。这两个过程已被广泛研究，特别是在幼苗中，但很少有人尝试将它们分开实验或区分不同的分生组织和组织中存在的芽。在实生苗中，芽和维管形成层的各个过程的年周期可概括为：（1）芽伸长生长停止和顶芽形成（其中叶原基起始）在夏末设置，之后形成层停止生长，芽发育发生并且耐霜冻性开始增加;（2）休息（内休眠）在芽后的秋季和暴露于低温后的分生组织中发展（约2至10°C），变为静止（生态休眠）到仲冬，此时抗冻性最高;（3）抗冻性极低（−3至−10°C）从春天的萌芽和形成层重新激活到秋天的生长停止（Riding and Little，1984; Mellerowicz et al.，1992 a; Dormling，1993; Qamaruddin et al.，1993;本书其他章节）。
Under natural environmental conditions, frost tolerance is temporally associated with dormancy in the shoots of conifers and other tree species native to the Temperate Zone. Both processes have been extensively studied, particularly in seedlings, but little attempt has been made to separate them experimentally or to distinguish between the various meristems and tissues present in the shoot. In seedlings, the annual cycle in each process can be summarized for both buds and the vascular cambium as follows: (1) shoot extension growth stops and terminal buds (in which leaf primordia are initiated) are set in late summer, after which the cambium ceases growing, bud development occurs and frost tolerance begins to increase; (2) rest (endodormancy) develops in the meristems during autumn after budset and, after exposure to chilling temperatures (about 2 to 10°C), changes into quiescence (ecodormancy) by mid-winter, when frost tolerance is maximal; and (3) frost tolerance is minimal (−3 to −10°C) from budbreak and cambial reactivation in the spring until growth cessation in the autumn (e.g. Riding and Little 1984; Mellerowicz et al. 1992a; Dormling 1993; Qamaruddin et al. 1993; other chapters in this book).
