Net photosynthesis was measured under field conditions in 23-year-old slash pine (Pinus elliottii Engelm. var. elliottii) trees to determine how it was affected by fertilization and climate. There was only a small decrease in rates of net photosynthesis from late summer through winter demonstrating that appreciable carbon gain occurs throughout the year in slash pine. Although fertilization sub...

During the early 1900s, nearly 37 million hectares of land in Southern United States were under longleaf pine ( Pinus palustris ) relative to current area 1.6 hectares. This study compares economics southern pines (longleaf, loblolly taeda ), and slash elliottii )) facilitate decision making family forest landowners design suitable financial incentives for increasing region.
