Dr. Bao-Luo Ma
Dr. Ma conducts nationally and internationally recognized research that supports the STB science priorities of identifying plant traits for cultivar improvement, and designing best management strategies and crop production systems that improve agriculture productivity, sustainability and profitability.
Specifically, his research projects are designed to understand crop plant reactions to abiotic stresses as well as to develop risk assessment technologies for different environment-induced stresses in crop stand establishment, growth, development, and yield formation under nutrient-limited (deficiency or over-fertilization), saline, drought, cold, crowded or other adverse conditions. The overall objectives are identification, understanding, and mitigation of risks associated with abiotic stresses impacting cropping systems.
