Other claims from this paper (11)
- Intervention effect Supplementary UV-B radiation reduced bean yield.
- Intervention effect Water stress reduced bean yield.
- Intervention effect Supplementary UV-B radiation changed net photosynthetic rate and stomatal conductance of bean without a stated direction.
- Intervention effect Water stress changed net photosynthetic rate and stomatal conductance of bean without a stated direction.
- Observation H2O2 content and lipid peroxidation increased in bean under the stresses, indicating oxidative damage.
- Intervention effect sUV-B had a stronger stress effect on bean than water stress.
- Intervention effect sUV-B caused greater membrane damage in bean than water stress, as assessed by lipid peroxidation and osmolyte leakage.
- Intervention effect Ascorbate peroxidase and superoxide dismutase activities increased in bean under both stresses alone and in combination.
- Intervention effect Catalase activity in bean decreased under water stress compared with the control.
- Intervention effect The combination of drought and UV-B caused more severe damage to bean than the stresses applied separately, and the effect was more than additive.
- Intervention effect Water stress induced accumulation of UV-B absorbing secondary pigments in bean.
