Growth, yield and plant water relationships in sweet potatoes in response to carbon dioxide enrichment: Progress report
In the summer of 1985, under the joint program of US Department of Energy, Carbon Dioxide Division, and Tuskegee University, experiments were conducted to study growth, yield, photosynthesis and plant water relationships in sweet potato plants grown in an enriched CO/sub 2/ environment. The main experiment utilized open top chambers to study the effects of CO/sub 2/ and soil moisture on growth, yield and photosynthesis of field-grown plants. In addition, potted plants in open top chambers were utilized in a study of the effects of different CO/sub 2/ concentrations on growth pattern, relative growth rate, net assimilation rate and biomass increment at different stages of development. The interaction effects of enriched CO/sub 2/ and water stress on biomass production, yield, xylem potential, and stomatal conductance were also investigated. 29 refs., 18 figs., 41 tabs.
