Wheat is one of the major crops grown commercially and an important source of nutrition for humans. Changes in grain quality due to increasing levels of atmospheric CO2 could have far-reaching impacts to human diets globally. Future wheat-growing conditions are expected to be impacted by climate change, particularly increases in carbon dioxide. Elevated CO2 (eCO2) has been shown to increase plant growth and yield, yet changes in grain properties also affect product quality.Using Australian Grains Free Air CO2 Enrichment (AGFACE) technology we investigated the impacts of eCO2 on grain quality over three seasons.Elevated CO2 consistently decreased baking quality and grain protein percentage wa..View full abstract
