Nine soybean cultivars widely cultivated in Northeast China were investigated in present study to assess their O3 sensitivities on the basis of the response of photosynthesis and seed yield to ambient and future ozone (O3) concentrations, and determine whether the effects of O3 vary with the developmental stages (flowering and seed filling stages). Relative to charcoal-filtered air (CF), elevated O3 concentration (E-O3, ambient air+40 ppb) significantly reduced soybean yields by 40%, with a… CONTINUE READING
