【摘要】 臭气(O3)被认为最主要的空气污染物之一。目前地球对流层大气中平均 O3浓度已经从工业革命前的38 nl l-1(25-45 nl l-1,夏季每天8h 平均)上升到2000年的50 nl l-1,这个浓度已经超过了敏感作物 O3伤害阀值的25%,悲观估计到2100年近地层 O3浓度将上升到 80 nl l-1。水稻是世界特别是亚州最重要的粮食作物,因此,准确评估近地层 O3浓度升高对水稻生长发育的影响具有特别重要的意义。本文从叶片伤害特征、光合作用、水分关系、生育期、物质生产与分配、叶片膜保护系统、籽粒产量及产量构成因素等方面,系统收集和整理了气室条件下(包括封闭气室、开项式气室)高 O3浓度对水稻生长发育影响的研究进展,并讨论了该领域有待深入研究的方向。
【Abstract】 Ozone (O3) is now recognized as one of the most important air pollutant.Current worldwide average tropospheric O3 values have increased from an estimated pre-industrial level of 38 nl 1-1 (25-45 nl 1-1,8-h summer seasonal average) to approximately 50 nl 1-1 in 2000,the most pessimistic projections suggest a further increase to 80 nl 1-1 by 2100.Oryza sativa L.(rice) is the most important crops in the world,so it is particularly important to correctly evaluate how the predicted increase in the levels of atmospheric ozone concentration will affect growth and development of rice.This review mainly focused upon chamber-based studies (include closed chambers or open top chambers) of the effects of atmospheric ozone enrichment on rice crops with regard to visible injury symptom,photosynthesis,water relationship,phenology,dry matter production and allocation,membrane protective system of leaves,grain yield and its components. Based on the current situation,further research orientation in this field was discussed.
