Abstract

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).

大气CO2浓度升高对玉米和水稻生长特性和产量的影响

为了评估增加大气CO2浓度（[CO2]）对玉米和水稻生长和产量的影响，在中国江苏南京的不同大气CO2浓度处理（550？mol/mol，T1；750？mol/mol、T2和对照，CK）下，在开放顶室（OTCs）中进行了实验。结果表明，玉米（郑单958）和水稻（怀稻5号）在三个发育阶段的株高、叶面积指数（LAI）、土壤和植物分析仪发育（SPAD）和净光合作用（NPn）在[CO2]增加的情况下遵循CK 0.05的顺序。

期刊介绍： ''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered. ''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
