摘要: We aimed at evaluating the effect of low-level air pollution on leaf area fluctuating asymmetry (FAA) and specific (SLA) Salix alba L., taking into account other environmental factors. Cuttings were grown in standardized conditions near vicinity quality measuring stations Belgium. Variability SLA FAA between explained 83% 7.26%, respectively, total variability. was not influenced by or factors such as shading, herbivory, temperature humidity. increased an increase shadow, while NO(x) O(3) concentrations had only a marginal influence. The influence SO(2) concentration negligible. Although our data analysis suggests relationship NO(x)/O(3) concentration, absence straightforward still questions usefulness these bio-indicators for monitoring pollution.
