摘要
本文利用 OTC- 1型开顶式气室对水稻进行了不同 O3浓度处理 ,试验研究了不同 O3浓度对水稻生长发育、生理过程和产品品质的影响。结果表明 :当大气中 O3浓度增加时 ,水稻的气孔阻力增加、光合作用速率下降、蒸腾速率也下降。水稻的生物量减少 ,产量下降 。
The different O 3 concentration treatments on rice were conducted in open top chambers. The impacts of different O 3 concentration on rice growth and devel opment, physiological process and grain qualities were studied. The results show n that when the atmospheric O 3 concentration increase, the stomatal resistanc e would increase, while the photosynthesis rate and transpiration rate would dec rease; the rice biomass and grain yield would decrease; but the grain qualities would improve.
