Effects of organic fertilizer on flag leaf (A) POD activity, (B) SOD activity and (C) MDA content of two wheat cultivars under water stress and well-watered conditions at 14 d after anthesis.
CK: control; M: organic fertilizer; WS: water stress; WW: well-watered. All data were presented as the mean± SD of six replicates. Duncan’s multiple range test in the SPSS System was used to separate the means, different lowercase letters represent significant different (P≤0.05).

Changes in Fv/Fm of the flag leaf of two wheat cultivars, CH58 (A) and XN9871 (B) under organic fertilizer and different water regimes.
CK: control; M: organic fertilizer; WS: water stress; WW: well-watered. Bars are LSD at P≤0.05.

Changes in chlorophyll content in the flag leaf of two wheat cultivars, CH58 (A) and XN9871 (B) under organic fertilizer and different water regimes.
CK: control; M: organic fertilizer; WS: water stress; WW: well-watered. Bars are LSD at P≤0.05. Effects of organic fertilizer on photosynthetic characteristics.

Changes in (A, E) net photosynthetic rate (Pn), (B, F) transpiration rate (Tr), (C, G) stomatal conductance (gs), and (D, H) water-use efficiency at the leaf level (WUEi) during the grain-filling stage of two cultivars, CH58 (A-D) and XN9871 (E-H) under organic fertilizer and two water regimes.
Organic fertilizer: M; control: CK; WS: water stress; WW: well-watered. Bars are LSD at P≤0.05.

The grain-filling rates were calculated according to the Richard equation [34]. CK: control; M: organic fertilizer; WS: water stress; WW: well-watered. Bars are LSD at P≤0.05.

CK: control; M: organic fertilizer; WS: water stress; WW: well-watered. Bars are LSD at P≤0.05.
