摘 要 ：本文对棉花盛铃期的株冠结构进行了不同层次的光合特性分析,用放射性同位素整株标记法研究了棉花株冠不同层次光合器官的相对光合强度,~(14)C—同化物的运输和分配以及棉花群体的相对呼吸强度;揭示了棉花盛铃期复杂株冠结构与光合特性的联系,为高产育种和栽培提供了部分理论依据。

Abstract:Photosynthetic characteristics of different layers of cotton canopy inthe maximum bolling stage were studied by the radioisotope labeling technique in the whole plant.The results showed that there was differencoin photosynthesis between the upper and middle-lower leaves.The subtending leaves had hig
