Other claims from this paper (18)
- Intervention effect N2 enhanced grain nitrate reductase and glutamine synthase activities relative to N1 under heat stress.
- Intervention effect N2 enhanced grain nitrate reductase and glutamine synthase activities relative to N1 under drought stress.
- Intervention effect N2 increased photosynthetic rate, PSII efficiency and instantaneous WUE relative to N1 under individual post-anthesis stresses.
- Intervention effect N3 increased photosynthetic rate, PSII efficiency and instantaneous WUE relative to N1 under individual post-anthesis stresses.
- Intervention effect Under combined stress, N1 usually significantly improved photosynthetic rate, PSII efficiency and instantaneous WUE.
- Intervention effect Nitrogen application increased green leaf area, aboveground dry mass and height in association with increased photosynthesis.
- Association Leaf nitrogen content per unit area explained variation in photosynthetic rate more accurately.
- Intervention effect Post-anthesis heat stress decreased yield by reducing grain number and thousand kernel weight.
- Intervention effect Combined post-anthesis stress decreased yield by reducing grain number and thousand kernel weight.
- Intervention effect Combined stress reduced NUE more than individual heat or drought.
- Intervention effect N2 significantly prevented decreases in yield and NUE relative to N1 under individual heat and drought.
- Intervention effect N3 significantly prevented decreases in yield and NUE relative to N1 under individual heat and drought.
- Intervention effect N1 was conducive to improving wheat productivity, WUE and NUE under combined stress.
- Recommendation The authors recommend appropriately increasing nitrogen under individual post-anthesis heat or drought.
- Recommendation The authors suggest reducing nitrogen to N1 under combined stress to compensate for yield, WUE and NUE losses.
- Intervention effect Heat after anthesis reduced grain number per spike and thousand kernel weight.
- Intervention effect Drought after anthesis reduced grain number per spike and thousand kernel weight.
- Intervention effect Combined stress after anthesis reduced grain number per spike and thousand kernel weight.
