Roots exudation

The magnitude and composition of root exudates are a reflection of the physiological condition of the plant imposed by factors related to light (intensity, duration, and quality), temperature, soil pH, anaerobiosis, soil moisture, soil type, and nutritional status. The in-... [Pg.118]

Water-soluble root exudates are most frequently collected by immersion of root systems into aerated trap solutions for a defined time period (Fig. 1 A). The technique is easy to perform and permits kinetic studies by repeated measurements over time using the same plants. While it is possible to get a first impression about qualitative exudation patterns and even quantitative changes in response to different preculture conditions, the technique also includes several restrictions that should be taken into account for the interpretation of experimental data.
