摘要
近地层高浓度臭氧是重要的大气污染物之一,其对作物的生长会产生一系列影响。综述了近地层臭氧浓度升高对作物地上部分和地下部分的影响,地上部分的影响采用由表及里的方法,从对作物影响的表观现象出发,然后分析产生这种影响的机制;地下部分的影响从臭氧对作物根系生物量、根系分泌物、植株-土壤系统中营养元素、土壤酶以及作物菌根的效应进行分析。通过对比分析阐述了臭氧对地上地下部分影响之间的联系,简要的探讨了该领域研究的发展方向。结果表明:多数研究只是单独的分析臭氧对作物地上或者地下部分的影响,且现有的研究大部分都是针对臭氧浓度升高对作物的胁迫,在臭氧对作物整体生长的影响及如何消除臭氧对作物影响方面的研究还需加强。
The increased near-surface ozone concentration will influence the growth of crops, which results in series of changes in the crop, including the aboveground parts （ such as crop morphology, yield and metabolism） and underground parts （ such as crop root biomass, root exudates, plant-soil system nutrients, soil enzymes and crop mycorrhiza）. In this research field, many efforts and achievements were achieved. This paper gave a review of ozone effects on crops both in aboveground and underground parts. The ozone effects on crop research results and the focus on this field were analyzed. The prospecting effects of ozone on crops and research trends in future were discussed. The result showed that most of studies focused on the effect of ozone concentration on aboveground parts and underground individually. Much efforts were devoted to the stress on crops when the concentrations of ozone elevated. However, the effect of elevated ozone concentration on the whole crop including the aboveand underground parts, was lacked as well as the elimination and mitigation fields should be enhanced. methods of the impact on crops. Therefore the research on these
