Soil quality — Responses of higher plants to environmental stresses — Part 1: Physiological parameters

Scope

This technical specification describes a set of physiological (Part 1) and biochemical (Part 2) parameters allowing to measure sublethal effects in higher plants exposed to soil pollutants. It is applicable to soils of unknown quality e.g. from contaminated sites, amended soils or soils after remediation either in situ or laboratory exposure assays. For in situ experiments the areas to compare shall be exposed to the same climatic conditions (humidity, temperature, sunlight). This part specifies a toolbox of methods for analysing variations in physiological parameters and oxidative balance that may be indicative of stress symptoms in higher plants, either monocotyledonous and dicotyledonous species.
