Other claims from this paper (8)
- Intervention effect UV-B caused the greatest reductions in lettuce leaf expansion and final leaf size.
- Intervention effect UV-A wavelengths contributed some reductions in lettuce leaf expansion and final leaf size.
- Intervention effect In field plants under increased UV, cell size and cell number were lower.
- Intervention effect Under increased UV in CE plants, abaxial cells were lower.
- Intervention effect UV wavelengths did not affect lettuce leaf turgor or leaf extensibility.
- Intervention effect Supplementary UV-B decreased the breaking strain of lettuce leaf tissue.
- Intervention effect Cell-wall peroxidase activity increased under supplementary UV and in the field.
- Intervention effect Only the zero UV environment showed no upregulation of cell-wall peroxidase activity.
