图1 不同浓度CO2对冬小麦地上生物量的影响 ACO2表示大气二氧化碳浓度, ECO2表示升高二氧化碳浓度。误差线表示标准差。“NS”表示在同一生育时期不同处理间差异未达到显著水平(P > 0.05)。“*”表示在同一生育时期不同处理间差异达到显著水平(P < 0.05)

Fig. 1 Effects of different concentrations of CO2 on aboveground biomass of winter wheat ACO2: atmospheric carbon dioxide concentration, ECO2: elevated carbon dioxide concentration. The error line represents the standard deviation. “NS” indicates no significantly different among the treatments in the same stage at P < 0.05. “*”indicates significantly different among the treatments in the same stage at P < 0.05.
