A key feature of the perennial life style in plants is the ability to cease meristem activity and to establish a dormant state in which the meristem is rendered insensitive to growth-promoting signals for some time before it is released and can resume growth. The seasonal cycling between growth and dormancy has received little attention despite its importance for perennial behaviour. In this review, we reconsider seasonal cycles of growth and dormancy in view of a new definition of dormancy as a state within the meristem, together with recent exciting developments in the study of perennials, particularly the identification of common signalling intermediates between flowering time and growth cessation in trees.
植物多年生生活方式的一个关键特征是能够停止分生组织活动并进入休眠状态，在这种状态下，分生组织在一段时间内对生长促进信号不敏感，直到解除休眠并恢复生长。尽管生长与休眠之间的季节性循环对多年生植物的生长行为很重要，但却很少受到关注。在这篇综述中，鉴于将休眠重新定义为分生组织内的一种状态，以及多年生植物研究中最近令人兴奋的进展，特别是树木开花时间与生长停止之间共同信号中间体的鉴定，我们重新审视了生长与休眠的季节性循环。
