- Intervention effect Suitable sulfur rates improved wheat nitrate reductase activity.
- Intervention effect Under N330, sulfur fertilization reduced wheat nitrate reductase activity.
- Intervention effect At 330 kg/hm2 nitrogen, sulfur inhibited wheat chlorophyll SPAD response.
- Observation Flag leaf soluble protein increased during growth and then fell after its anthesis maximum.
- Intervention effect At a fixed nitrogen level, increasing sulfur increased flag leaf soluble protein content.
- Observation Flag leaf photosynthesis velocity declined from flowering.
