The Effects of parental CO2 and offspring nutrient environment on initial growth and photosynthesis in an annual grass
2001
Seeds of Bromus madritensis ssp. rubens (red brome, an exotic annual grass in the Mojave Desert), from parents grown at three CO2 levels (360, 550, and 700 μmol mol−1), were grown in factorial CO2 (360, 550, and 700 μmol mol−1) and nutrient (zero addition, 1:40‐strength, and 1:10‐strength Hoagland’s solution) environments to evaluate parental CO2 effects on offspring performance characteristics across a range of developmental environments. We evaluated growth rate, leaf nitrogen content, and photosynthetic gas exchange over a 3‐wk period.
