Other claims from this paper (10)
- Intervention effect Under T2, grain yield and WUE were the highest among all treatments.
- Intervention effect Under T3, the ratio of one-grained and double-grained ear, grain number per spike and grain yield were all the lowest.
- Intervention effect Under T3, WUE was the lowest among treatments.
- Intervention effect Water deficit increased the ratio of invalid ear, the highest among treatments.
- Association Grain yields under the three irrigation treatments were significantly positively correlated with WUE.
- Association Under T3, grain yield and WUE were negatively correlated with grain number per spike.
- Association Under T3, grain yield and WUE were significantly positively correlated with grain weight per spike.
- Association Under T1 and T2, grain number per spike was significantly positively correlated with grain weight per spike.
- Association Under T3, grain number per spike showed no correlation with grain weight per spike.
- Mechanism Water deficit decreased grain yield and WUE, as a result of a lower ratio of one-grained and double-grained ear, a higher ratio of invalid ear, and lower grain plumpness and grain weight per spike.
