植物的发育是精心安排的，但又是灵活的。这使得在先前和当前环境线索的背景下能够形成正确的器官。利用以前的环境经验，如种子形成时的条件或冬天是否已经过去，对于最大限度地提高繁殖成功率至关重要。温度是实现这一目标的关键信号，它提供了当前的季节信息，是即将到来的环境条件，包括干旱或冰冻的指标。因此，许多温度反应促进环境适应，以及触发关键的发育变化，如发芽，生长和开花。研究已经确定，温度信号在光信号、昼夜节律和光强度以及发育阶段的背景下被解释。此外，许多温度提示是与非常高或非常低的温度相关联的压力信号。这些信号确实会触发发育反应，但不是标准发育生长的一部分。本文重点介绍了环境温度对植物发育的每个主要阶段的作用。
Plant development is orchestrated and yet flexible. This enables the formation of the correct organs within the context of previous and current environmental cues. The use of previous environmental experiences, such as the conditions when the seed formed or whether winter has passed, is critical to maximise reproductive success. Temperature is a crucial signal in achieving this, it provides current seasonal information and is an indicator of forthcoming environmental conditions, including drought or freezing. Therefore, many temperature responses facilitate environmental acclimation as well as trigger key developmental changes, such as germination, growth, and flowering. Research has identified that temperature signals are interpreted in the context of light signalling, circadian and light intensity, and developmental stage. Furthermore, a number of temperature cues are stress signals, associated with very high or low temperatures. These signals do trigger developmental responses but not as part of standard developmental growth. This article focuses on the role of ambient temperature on each of the major stages of plant development.
