主要研究成果:1. 阐明了CO2传输能力是作物高光效的关键限制因子。本课题组以水稻为主要研究对象,综合运用作物生理学、植物解剖学和生物化学等多学科的研究方法,并结合光合模型阐明了CO2传输能力是作物高光效的关键限制因子,明确了CO2传输对温度、氮肥和干旱等主要环境因子的响应机制;2. 揭示了作物高光效的叶片、根系和穗颈的生物学结构。叶片、根系、茎秆的生物学结构对作物生长发育起着重要作用,但是目前对于高光效作物的叶片、根系和茎秆的结构特征还缺乏系统的认识。本课题组综合运用光合模型和植物解剖学方法,阐明了叶片、根系和穗颈的生物学结构对作物光合效率的影响与机制,揭示了高光效作物的生物学结构特征,为作物高光效的品种选育提供了重要的理论指导和目标性状。
