Table 2 Demonstrate the effect of heat stress on different chlorophyll contents and chlorophyll fluorescence in soybean plants with and without inoculation of SA1 at different time point (0, 5 and 10 Days). (A) Chlorophyll fluorescence (Fv/Fm) (B) Chl a (C) Chl b and (D) carotenoid. Each data point is the mean of three replicates. Error bars represent standard errors. The bars represented with different letters are significantly different from each other as evaluated by DMRT analysis
