AbstractUnderstanding the responses of crops to elevated atmospheric carbon dioxide concentrations (E[CO2]) is very important in terms of global food supplies. The present study investigates the effects of CO2 enrichment (to 800 mu mol mol(-1)) on the physiology of soybean plants and the nutritional value of their seeds under growth chamber conditions. The photosynthesis of soybean was significantly promoted by E[CO2] at all growth stages, but leaf area and specific leaf weight were not affected. The levels of mineral elements in the leaves decreased under E[CO2]. The soil properties after soybean cultivation under E[CO2] were not affected, except for a decrease in available potassium. Moreover, the levels of soluble sugars in the seeds were not affected by E[CO2], but the levels of natural antioxidants decreased. In addition, the level of oleic acid decreased under E[CO2]. However, levels of fatty acid peroxidation and saturation were maintained. In conclusion, E[CO2] appears to have positive effects on the growth of cultivated soybean plants, but its influence on the nutritional values of soybean seeds is complex.
