Other claims from this paper (11)
- Intervention effect Water deficit decreased shoot and root lengths and shoot dry weight of wheat in the greenhouse.
- Intervention effect Water deficit decreased root dry weight and water utilization efficiency of wheat.
- Intervention effect Water deficit decreased chlorophyll a and b and chlorophyll stability index of wheat.
- Intervention effect Foliar silicon improved plant growth parameters and chlorophyll pigment concentration of wheat under water deficit.
- Intervention effect Foliar silicon did not significantly affect wheat growth under control conditions.
- Intervention effect Limited water supply reduced effective quantum yield of PSII, photochemical quenching and apparent electron transport rate of wheat leaves.
- Intervention effect Under water deficit, foliar silicon increased the chlorophyll fluorescence parameters of wheat that water deficit had reduced.
- Intervention effect Under water deficit, foliar silicon further improved nonphotochemical quenching (qN) and F0/Fm of wheat.
- Mechanism Chlorophyll fluorescence analysis suggests that silicon alleviated water-deficit adverse effects in wheat by reducing nonphotochemical quenching while increasing Fv/Fm and qP.
- Intervention effect Silicon improved the light use efficiency of wheat cultivars under water stress.
- Intervention effect Drought-sensitive wheat cultivars Shiraz and Marvdasht could resemble resistant cultivars after foliar silicon application.
