本文总结了作者多年来关于棉花光合生理和物质运输问题的田间和室内试验结果。阐明了碳、磷、硫放射性同位素示踪物质的转移规律;分析了应用放射自显影、辐射测量和薄层色谱等方法研究的棉花同化物质的运输特点。文章首先论述了调节棉花同化产物运输的整枝技术、化学和育种措施等方面的踪合研究情况;对于探讨加速物质从同化器官向贮存器官运输而保证棉花增产的若干新方法,也给予了高度重视。 This article summarizes the authors’ field and laboratory results over the years on photosynthetic physiology and material transport in cotton. The translocation regularity of radioactive isotope tracer of carbon, phosphorus and sulfur was clarified. The characteristics of cotton assimilate transport were analyzed by means of autoradiography, radiation measurement and thin layer chromatography. In the first place, the article deals with the studies of the tracing studies on the pruning techniques, chemical and breeding measures to regulate cotton assimilate transport, and also attaches great importance to exploring some new methods for accelerating the yield increase of cotton from assimilating organs to storage organs .
