Table 5 The differences in tensile strength between 2 plants roots after self-repair and the parallel control roots.
Plant species | Root diameter (mm) | Tensile strength of the control roots (MPa) | Tensile strength and induction rate after self-repair under different injury force | |||
|---|---|---|---|---|---|---|
Small injury force (MPa) | Reduction rate (%) | Large injury force (MPa) | Reduction rate (%) | |||
