摘要: BackgroundElevated CO2 usually reduces levels of proteins and essential micronutrients in crops. The adoption of early-maturing varieties may minimise the deleterious effect of climate change on farming activities. Since legumes stand out for their high nutritional quality the objective was to study if the atmospheric CO2 concentration affected growth, yield and food quality of earlymaturing cultivars of pea, snap bean and faba bean. Plants grew in greenhouses either at ambient (ACO2, 392 µmol mol-1) or under elevated (ECO2, 700 µmol mol-1) CO2. Minerals, proteins, sugars and phenolic compounds were measured in grains of pea and faba bean, and in pods of snap bean.
