摘　　要：植物花后光合性能及物质运转对籽粒产量具有重要贡献,在植物整株物质生产中具有重要价值。本文重点从植物花后叶绿素的含量、绿色非叶器官的结构与功能、花后叶片和绿色非叶器官的光合性能及其物质运转等方面综述了花后植物的光合性能及物质转运的研究进展。研究植物花后不同冠层或穗位光合同化物的生产及转运情况,明确植物花后绿色非叶器官的光合途径及机制,可以为植物高产或超高产研究提供理论依据,进一步了解其对储藏过程中种子老化劣变的影响,为解决粮食及种子储藏问题探寻新思路。Photosynthetic performance and material transport of post-anthesis plants played a very important role in photosynthetic production and were the significant assimilation sources of grain-filling stage.The research progress of photosynthetic performance and material transport of post-anthesis plants were reviewed from chlorophyll content,the structure and function of non-leaf green organs,the photosynthetic performance of leaf as well as non-leaf and its contribution to grain yield.Comprehensive analysis showed that the photosynthetic pathway and mechanism of non-leaf green organs of post-anthesis were defined by studying the photoassimilate production and transshipment of different canopies or ears and a theoretical basis of studying plant high or super-high yield was provided.The deteriorated effects of grain and seed during forage could be further understood by studying the photosynthetic performance and material transport of post-anthesis plants.
