Popis: To assess the effect of increasing atmospheric CO2 concentration ([CO2]) on growth and yield in maize and rice, an experiment was carried out in open top chambers (OTCs) at different atmospheric CO2 concentration treatments (550 ?mol/mol, T1; 750 ?mol/mol, T2 and a control, CK) in Nanjing, Jiangsu, China. Our results indicated that the plant height, leaf area index (LAI), Soil and Plant Analyzer Development (SPAD) and net photosynthesis (NPn) of the maize (Zhengdan 958) and rice (Huaidao 5) at three development stages under the increasing [CO2] followed the order of CK 0.05).
