Evaluate changes in leaf angle in response to elevated temperature and carbon dioxide concentration.
Initial studies with tomato (Solanum lycopersicum) have shown an increase in leaf angle (hyponasty) when exposed to elevated temperature and carbon dioxide concentration. First, we will investigate the prevalence of this phenomenon in additional species and determine if its occurrence is related to leaf type (simple or compound) or family. Second, we will investigate if this phenomenon occurs only during specific stages of growth and development (e.g., seedling, vegetative, flowering, and/or fruiting). Third, we will evaluate the impact of light intensity, quality, and direction on the severity of the hyponasty response.
