Superoptimal Co2 Reduces Seed Yield In Wheat, Timothy P. Grotenhuis
Superoptimal Co2 Reduces Seed Yield In Wheat, Timothy P. Grotenhuis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Although projected terrestrial CO2 levels will not reach 1000 μmol moI-1 (0.1%) for many decades, CO2 levels in growth chambers and greenhouses routinely exceed that concentration. CO2 levels in life support systems in space can exceed 10,000 μmol moI-1 (1%) CO2. Numerous studies have examined CO2 effects up to 1000 μmol mol-1, but theoretical and some experimental evidence indicates that the beneficial effects of CO2 continue past 1000 μmol mol-1 and are near-optimal for wheat at about 1200 μmol mol-1.
We studied the effects of near-optimal …
