Title: Growth, Development and Carbon Capture of Varietal Loblolly Pine as Influenced by Silviculture

Summary: Elite genotypes of loblolly pine, including varietals, are now being deployed to improve growth rates, stem straightness and disease resistance.  The ability to predict potential site-specific interactions between specific genotypes and silvicultural management will be necessary to efficiently utilize this elite and expensive material.  We have been examining physiological and morphological mechanisms related to varietal growth responses with the practical goal of aiding in early, rapid selection of successful varietal material. 

Presenter: John Seiler, Ph.D., the Honorable and Mrs. Shelton H. Short Professor of Forestry, Virginia Tech, Department of Forest Resources and Environmental Conservation, Blacksburg, Virginia

John Seiler received BS degrees in Forest Science and Environmental Resource Management from The Pennsylvania State University in 1979.  He remained at Penn State and earned a Master’s degree in Forest Biology in 1981.  In the fall of 1981, he began his studies for a Ph.D. in Tree Physiology and completed all requirements in 1984.  He has been a member of the Department of Forest Resources and Environmental Conservation faculty at Virginia Tech since 1985 where he researches the effects of various environmental impacts on tree biology and growth.  Along with his graduate students he has published over 85 referred articles on the subject.  Four of his Ph.D. students have received Outstanding Graduate Student awards.  In the past, he has researched water stress, acid rain, ozone and elevated CO2 effects on forest trees.  His most recent research is investigating the physiological mechanisms responsible for enhanced tree growth due to genetics and management.  He has taught a wide variety of classes including dendrology (tree identification), forest biology, silviculture, forest fire management, plant water relations, advanced forest ecology, and tree physiology.  He also teaches an online course called Forest Ecology and Dendrology for Educators that was designed for public school biology teachers to take during the summer months.  John and his colleagues have also developed a wide array of multimedia teaching tools to aid students in learning tree identification and forest biology.  As a result of this work, John and his team have won numerous state, national and international teaching related awards. He currently holds an endowed chair in the forestry department named in honor of the Honorable and Mrs. Shelton H. Short, Jr. from Southside, Virginia.
