臭氧(O3)被认为是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 n.lL-1(25~45 n.lL-1,夏季每天8 h平均)上升到2000年的50 nl.L-1,悲观估计到2100年近地层O3浓度将上升到80 n.lL-1.水稻是世界上最重要的粮食作物,准确评估近地层O3浓度升高对水稻生长发育的影响具有重要意义.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、开放式气室)高O3浓度对水稻生长发育影响的研究进展,并对该领域有待深入研究的方向进行了展望.
Ozone (O3) is considered to be one of the major air pollutants, and the average O3 concentration in the Earth’s troposphere has risen from 38 nl L-1 (25-45 nlL-1) before the Industrial Revolution to 8 h daily in summer Average) to 50 nl.L-1 in 2000, a pessimistic estimate of near-surface O3 concentration will rise to 80 nL-1 by 2100. Rice is the most important food crop in the world and an accurate assessment of the O3 concentration in the near-field High impact on rice growth and development is of great significance.This paper systematically collected and sorted from the injury characteristics of the leaves, photosynthesis, water relations, growth period, material production and distribution, leaf membrane protection system, grain yield and yield components The research progress on the effect of high O3 concentration on the growth and development of rice under the condition of air chamber (including closed air chamber and open air chamber) is prospected, and the direction to be further studied in this field is prospected.
