We assessed the effects of carbon dioxide (CO₂) and decabromodiphenyl ether (BDE-209, 0, 3 and 30 mg/kg) on rice (Oryza sativa L. cv. Wuyunjing) in field free-air CO₂ enrichment system. Rice at elevated (580 ppm) CO₂ had increased net photosynthetic rate, intercellular CO₂ concentration, shoot biomass, yield and phosphorus content in grains. However, there were no significant changes in such parameters observed on rice at elevated CO₂ combined with BDE-209 (3 and 30 mg/kg). Elevated CO₂ alone had no significant effects on sugar or starch content in rice grains, whereas its combination with BDE-209 (3 mg/kg) significantly decreased grain sugar and starch content. In conclusion, rice reared in soil polluted by BDE-209 under elevated CO₂ modulates the effects in grain feature.

十溴二苯醚和二氧化碳含量升高对水稻（Oryza sativa L.）的影响。

我们在田间自由空气CO ₂富集系统中评估了二氧化碳（CO ₂）和十溴二苯醚（BDE-209、0、3和30 mg / kg）对水稻（Oryza sativa L. cv。Wuyunjing）的影响。升高（580 ppm）CO _2的水稻提高了净光合速率，细胞间CO ₂浓度，苗生物量，产量和籽粒中的磷含量。但是，在高浓度CO ₂与BDE-209（3 mg / kg和30 mg / kg）联合使用时，在水稻上观察到的这些参数没有显着变化。升高的CO ₂单独使用对稻谷中的糖或淀粉含量没有显着影响，而将其与BDE-209（3 mg / kg）联合使用可显着降低稻米的糖和淀粉含量。总之，在高CO ₂浓度下，BDE-209污染的土壤中养育的水稻调节了籽粒特性的影响。
