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 ,但水稻的品质有提高
In this paper, OTC-1 type open-top gas chamber was used to treat rice at different O3 concentrations, and the effects of different O3 concentrations on the growth and development, physiological processes and product quality of rice were studied. The results showed that the stomatal resistance increased, photosynthesis rate decreased and transpiration rate decreased when O3 concentration in the atmosphere increased. The biomass of rice is reduced and the yield is reduced, but the quality of rice is improved
