t0“bread wheat”
e0“two field experiments were carried out in 2021/22 and 2022/23 in Arsanjan, Iran”
e2“the sub plots were irrigation levels at 100% (control), 80% (medium stress), and 60% (severe stress) of crop evapotranspiration”
e3“Drought stress caused a significant decrease in grain yield (46.4%), number of ears (20.5%), seed number (30.3%), biological yield (45.9%), chlorophyll a (31.8%), chlorophyll b (28.1%) and relative water content (5.3%) and increased, proline content (24.3%) and ion leakage (147.3%)”

- Intervention effect Drought stress decreased the number of ears of bread wheat by 20.5% compared with the control.
- Intervention effect Drought stress decreased seed number of bread wheat by 30.3% compared with the control.
- Intervention effect Drought stress decreased biological yield of bread wheat by 45.9% compared with the control.
- Intervention effect Drought stress decreased chlorophyll a of bread wheat by 31.8% compared with the control.
- Intervention effect Drought stress decreased chlorophyll b of bread wheat by 28.1% compared with the control.
- Intervention effect Drought stress decreased relative water content of bread wheat by 5.3% compared with the control.
- Intervention effect Drought stress increased ion leakage of bread wheat by 147.3% compared with the control.
