Other claims from this paper (11)
- Intervention effect Heat stress lowered net photosynthetic rate and chlorophyll content of both maize hybrids compared with ambient temperature control.
- Intervention effect Heat stress lowered the activities of Rubisco and phosphoenolpyruvate carboxylase (PEPC) in both maize hybrids compared with the control.
- Intervention effect Heat stress decreased dry matter accumulation of maize.
- Intervention effect The heat-stress decrease in dry matter accumulation was smaller for ZD958 than for XY335.
- Intervention effect Increasing nitrogen supply alleviated the adverse effects of heat stress on maize photosynthesis, due to improved nitrogen assimilation capacity.
- Intervention effect Under heat stress, high nitrogen treatment gave greater N content in maize ear leaf than low and medium nitrogen.
- Intervention effect Under heat stress, high nitrogen treatment gave higher activities of glutamine synthetase and glutamate synthase in maize ear leaf than low and medium nitrogen.
- Intervention effect High nitrogen with higher N assimilation capacity directly increased net photosynthetic rate, due to improved chlorophyll content, Rubisco and PEPC activities and antioxidant capacity.
- Intervention effect High nitrogen enhanced stomatal conductance and transpiration rate under heat stress to maintain higher photosynthetic capacity compared with low and medium nitrogen.
- Intervention effect Under heat stress the positive effects of increasing N supply on maize photosynthesis were larger for XY335 than for ZD958.
- Intervention effect Through improved photosynthesis and N assimilation capacity from adequate N supply, maize accumulated more biomass under heat stress, especially the heat-sensitive hybrid.
