Controlled experiments are increasingly important for investigating how and to what degree plant phenology responds to global climate change. Current experiments underline that chilling and forcing temperatures are two major environmental cues shaping the budburst date of temperate species, but whether experiments could reflect the observed responses to chilling has rarely been examined.

对照实验未能捕捉植物对低温的物候反应


对照实验对于研究植物物候如何以及在何种程度上响应全球气候变化变得越来越重要。目前的实验强调，寒冷和强迫温度是影响温带物种发芽日期的两个主要环境因素，但实验是否能够反映观察到的对寒冷的反应却很少被检验。
