Effect of different treatments on the MDA, chlorophyll, and water contents of seedling leaves before and after PEG application. (a) Effect of PEG application on the leaf MDA content of seedlings under different treatments. (b) Effect of PEG application on the leaf chlorophyll content of seedlings under different treatments. (c) Effect of PEG application on the leaf water content of seedlings under different treatments. PDB potato dextrose broth, PTD37 fermentation broth supernatant of the PTD37 strain, TR fermentation broth supernatant of T. harzianum. Data are the means ± SD from five independent tests. Different letters on error bars indicate significant differences at P = 0.05 between the analyzed composition contents of seedlings from different treatments on the same day after PEG application. The values on day 0 after PEG treatment indicate that these values were measured before PEG application.
