Summary:

Loblolly pine, Pinus taeda, is a common southern softwood ranging from Georgia and the Carolinas to Texas. The fungus Cronartium quercuum f.sp. fusiforme is one the most destructive forest diseases in the south. This fungus infects both loblolly and slash pine (P. elliottii Engelm.), causing canker formation that frequently kills the infected branch. April and early May are when the pine infection cycle occurs in Georgia. The elongated swelling of the branches is the result of individual attacks on different parts of the tree. Many of the infected trees are unsuitable for product, causing millions of dollars to be lost a year because of the death of infected trees. In addition, trees with large galls on the main stem are unsuitable for many products. We report the chemical composition of loblolly pine infected with fusiform rust. Branches were collected in Athens, Georgia, and frozen. The branches not infected by fusiform were collected as the control. Spectroscopy was used to analyze lignin. This report presents and discusses the results. The aim of this study was to apply Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (NMR) to determine whether there were any structural modifications to the chemical composition of lignin from the fungus. Published information on fusiform rust analyzed by FTIR and NMR is limited in the literature. In this paper, we present a FTIR and NMR spectroscopic analysis of the chemical changes occurring in a softwood, loblolly pine, by fusiform rust.
