摘要/Abstract

摘要： 本文用不同夜间温度连续处理抽穗开花后的小麦植株，对旗叶的光合作用和单株产量进行了比较研究。结果表明夜间低温能明显延长叶片叶绿素含量缓降期和光合速率高值持续期，从而增加叶片的叶源量，提高产量。经计算缓降期延长一天，可使单株产量和千粒重分别提高2.0-2.5%和1.5-2.0%。夜间高温处理植株效果相反。试验进一步研究

关键词: 夜间温度，光合作用，叶源量，单株产量

Abstract: Individual wheat plants after flowering were put under different nighttime temperatures to study the influence of nighttime temperature on the photosynthesis of the flag leaf and yield per plant. The results indicated that low nighttime temperature condition could prolong the length of the Relative

Key words: Nighttime temperature, Photosynthesis, Leaf source capacity, Yield per plant
