摘要 The physiological challenges posed by climate change for seasonal, perennial plants include increased risk of heat waves, post-budbreak freezing (“false springs”), and droughts. Though considerable physiological work has shown that the traits conferring tolerance to these stressors – thermotolerance, cold hardiness, and water deficit stress, respectively – are not static in time, they are frequently treated as such. In this review, I synthesize the recent literature on predictable seasonal – and therefore, phenological – patterns of acclimation and deacclimation to heat, cold, and water deficit stress in perennials, focusing on woody plants native to temperate climates. I highlight promising, high-throughput techniques for quantifying thermotolerance, cold hardiness, and drought tolerance. For each of these forms of stress tolerance, I summarize the current balance of evidence regarding temporal patterns over the course of a year and suggest a characteristic temporal scale in these responses to environmental stress. In doing so, I offer a synthetic framework of “phenological physiology”, in which understanding and leveraging seasonally recurring (phenological) patterns of physiological stress acclimation can facilitate climate change adaptation and mitigation.
