Photosynthesis, water relations, and growth of planted Pinus strobus L. on burned sites in the southern Appalachians. [pdf]Paper  abstract   bibtex   
Physiology and growth of Pinus strobus L. seedlings were measured two years after planting on two clearcut and burned sites in the Southern Appalachians. Multiple regression analysis was used to relate seedling net photosynthesis to vapor pressure deficit, seedling crown temperature, photosynthetically active radiation (PAR), needle N, xylem water potential, and soil water. Analysis also related seedling size and growth to average net photosynthesis, leaf conductance, cumulative xylem water potential, soil water, needle N, seedling temperature, and PAR. Seedling net photosynthesis was significantly related to vapor pressure deficit, midday water potential, crown temperature, and PAR early in the growing season with vapor pressure deficit alone explaining 42 percent of the variation. As neighboring vegetation developed, light became more limiting and significantly reduced seedling net photosynthesis later in the growing season. Final seedling diameter was significantly related to competitor biomass, average photosynthetic rate, and needle N.
