Broomcorn millet (Panicum miliaceum L.) has been cultivated in arid or semi-arid area due to its high drought tolerance. Yet information on how elevated atmospheric CO2 concentration ([CO2]) affects the responses to drought of the productivity, photosynthesis, water-use efficiency and drought tolera...
