چکیده

Tree decline is a physiological phenomenon resulting from climatic disturbances that involves damage to forest ecosystems. This study examined the effects of tree on nutrient concentrations in leaves, bark, and wood Persian oak (Quercus brantii) trees. Trees were categorized by severity (healthy, slight, moderate, severe decline). Leaves collected middle outer parts crowns. Bark samples taken at breast height (1.3 m). The contents Mg, Ca, P, Fe, K, Na analyzed atomic absorption spectrophotometry flame photometry. As increased, foliage increased. However, P K bark lower trees higher classes. Moreover, tissues varied across different severities. variations may have been due defense mechanisms enhancing tolerance against induced stress. results suggested stoichiometry can reflect uptake ecosystems plant-environmental stress relationships.
