温度是一个重要的环境因子,影响了植物的生长发育。几乎没有一种生理作用不和温度发生直接或间接的关系。而温度又和其他的条件起着複雜的相互影响,影响着植物的一切生理活动。僅僅对於植物的发育来谈,温度也是特别重要。如所週知,有些植物在它们的生活过程中需要较低的温度,有的需要较高的温度。即使是同一种或同一品种的植物,温度对於它们一生中的影响也是有所不同。例如冬性禾谷類作物在生育初期需要较低温度,而後期则需要较高温度。其他如日夜的温差,各式的温度节奏,失常的温度,土層的温度……等都影响到植物的发育。Blaauw,A.H.等(1924,1932)用鳞茎類做了很多关於温度和发育的工作。
Temperature is an important environmental factor, affecting the growth and development of plants. Almost no physiological effect does not have a direct or indirect relationship with temperature. The temperature and the other conditions play a complex interaction, affecting all the physiological activities of plants. For the development of plants, temperature is of special importance. As we all know, some plants need lower temperature during their life, others need higher temperature. Even in the same or same species of plant, the effects of temperature on their life are different. For example, winter cereal crops require lower temperatures during early growth and later temperatures require higher temperatures. Others such as temperature difference between day and night, all kinds of temperature rhythm, abnormal temperature, soil temperature ... ... and so affect the plant's development. Blaauw, A.H. et al. (1924, 1932) do a lot of work on temperature and development with bulbous species.
