Figure 4

Effect of drought stress on the enzyme activity levels of (A,E) sucrose phosphate synthase (SPS), (B,F) sucrose synthase (SuSy), (C,G) acid invertase (AI), and (D,H) neutral/alkaline invertase (NI) in leaves and seeds. Standard deviations were calculated with three independent experiments each comprising two soybean plants. Different letters above vertical bars indicate significant differences between means at a p < 0.05 level.
