Figure 3.

Comparison between streptomycin and oxytetracycline translocation in citrus plants. Plants were incubated in oxytetracycline or streptomycin solution (200 µg·mL⁻¹) for 16 h and analyzed by ELISA. Columns with a p-value less than 0.05 indicate statistically significant differences between oxytetracycline and streptomycin by Student’s t-test.
