“…The root radius, which seems to be a good indicator of this kind of stress, increased with the increase in the resistance (Figure 2b). This response was the same at all sampling times and is due to an increase in the size and number of cortex cells as shown by Wilson et al (1977), Goss & Russell (1980), and Atwell (1990a).…”

“…However, these systems do not simulate actual soil conditions. A more realistic approach is based on the application of pressure either directly to the growing tissue (1) or to the growth medium (2,5,12). We have adopted and modified the triaxial cell system described by CollisGeorge and Yoganathan (5) to simulate a variable mechanical stress during which ethylene production by the plants can be continuously monitored.…”

“…Mechanical impedance generally decreases elongation and increases radial expansion of plant tissue (2,5,10,12,23). Increasing evidence suggests that the mechanisms by which the coleoptile or root senses an external mechanical impedance and transduces this stimulus into growth pressure involve hormonal regulation (6).…”
