Abstract
Abstract The chromatographic amino-contained profiles of the extracts of needles from healthy and damaged Picea trees sampled in two polluted areas of the Vosges region (Massif du Taenchel and Massif du Donon), France are compared. The most interesting differences refer to the content of arginine, the precursor of polyamines. A dramatic difference in arginine content was found between needles from damaged trees as compared to those from seemingly undamaged trees. High levels of arginine, a basic compound, could be required to protect cell metabolism against the acidity of its environment caused by acid rains. High arginine content would thus indicate the resistant-healthy state of the tree. Further research is directed to determine whether titration of arginine content would afford a biochemical diagnostic of metabolic impairment prior to visible damages.
