植物长期生长在CO2浓度不断升高的环境中,其结构和功能都将受到影响,这种影响不仅表现在植物的地上部分,同时也表现在植物的地下部分(根系),尤其是细根的长度、直径、产量、周转以及根与枝的分配模式等方面。植物根系结构和功能的改变影响植物地上部分和生态系统物质循环中的碳动态及土壤中碳库的变化。目前有关大气CO2浓度升高对根系动态影响的研究报道主要包括大气CO2浓度升高对根系结构(直径、分枝、长度、数量等)和根系生理(周转率、产量、碳分配模式等)的影响2个方面。目前,该领域研究还存在一些不足,例如在CO2浓度升高条件下,对植物根系内部的调控机制,以及由其引起的物质循环和能量流动的动态变化的了解较少;至今没有令人信服的证据说明大气CO2浓度升高使根系周转升高还是降低。今后应加强研究在CO2浓度升高条件下根系的周转变化和光合产物分配模式变化,CO2浓度升高和外界环境因素的共同作用对根系的影响,以及采用不同研究方法和研究对象在不同立地条件下开展升高CO2浓度对根系影响的对比研究等。
