Specialty: Plant Nutrition and Physiology

Research interests are directed toward whole plant physiology and regulation of plant nutrition. Emphasis is on the role of environmental conditions in regulation of plant growth and development through the processes of nitrogen and carbon assimilation and partitioning. Controlled-environmental facilities of the phytotron are utilized to alter the nitrogen and water uptake activities of the root system and the carbon assimilation activities of the shoot. The functional interdependence of root and shoot activities and their role in regulation of plant responses to environmental conditions and nutrient supply are examined. Aspects of plant response considered include nitrogen uptake rate of roots, photosynthetic rate of leaves, utilization and partitioning of nitrogen and carbon, source and sink activities, and dry matter allocation.
