【摘要】 本文对光合速率较高的野生一粒小麦（T.boeoticum.Boiss）的叶片解剖结构及光合生态反应进行初步探讨,并与普通小麦中国春（T.aestivum cv.Chinese Spring）作了比较。结果表明,野生一粒小麦在叶片维管束解剖结构、水分利用效率及光合速率对光、温和CO₂的反应方面类似于 C₄植物。但它仍具有较高的 CO₂的补偿点。可考虑将野生一粒小麦用于普通小麦光合作用的遗传改良计划。更多还原

【Abstract】 In this paper.a comparison between T.boeoticum and T.aestivum cv.Chinese Springin some photosynthetic characteristics were made.The results indicated that the wilddiploid T.boeoticum was similar to C₄ plants in leaf anatomy and in the response to light,temperature,CO₂ concentration and water.It was proposed that T.boeoticum with higherPn could be used in the genetic improvement of photosynthesis in wheat.更多还原
