The X-ray absorption near-edge spectroscopy (XANES) technique has been used to determine the chemical change of elements induced by bark diseases in Havea brasiliensis (rubber latex tree). The results show the good sensitivity of in situ XANES for characterizing the chemical structure of phosphorus, sulfur, potassium and calcium in healthy and diseased Havea brasiliensis. Important information for understanding the bark disease involved in the sulfur metabolism of plants was also obtained from XANES.
X射线吸收近边光谱（XANES）技术已被用于确定巴西橡胶树（橡胶树）树皮病害引起的元素化学变化。结果表明，原位XANES对表征健康和患病巴西橡胶树中磷、硫、钾和钙的化学结构具有良好的灵敏度。从XANES中还获得了有助于理解植物硫代谢中树皮病害的重要信息。
