| Abstract | MARTA, PONGOR SIMON. Effect of Free-Air CO2 Enrichment and Fertilization on Wood Properties of Loblolly Pine (Pinus taeda L.). (Under the direction of Dr. Ilona Peszlen, Dr. Perry Peralta and Dr. Jean-Christophe Domec). Investigating the effect of elevated carbon dioxide and fertilization on wood quality provides crucial information on how trees react to global climate change. Within the framework of the Duke Forest-Atmosphere Carbon Transfer and Storage (FACTS-1) project, loblolly pine (Pinus taeda L.) trees were exposed to ambient and elevated (ambient + 200μL L) free air CO2 enrichment (FACE) treatments since 1996. From 2005, one-half of each plot was fertilized at a rate of 11.2 g N m yr. After the 2010 growing season the 24to 27year-old trees were harvested and eight trees from each treatment group [elevated CO2/unfertilized (elevated CO2), ambient CO2/fertilized (fertilized), elevated CO2/fertilized (combined elevated CO2 and fertilized), and ambient CO2/unfertilized (ambient control)] were sampled. In the first study, eccentricity, density and ring width were measured and analyzed. Fertilization and the elevated CO2 treatment had significant effect on wood density. Ring width was influenced only by the fertilization treatment. Eccentricity was not affected by the |
