A Strong Impact of Soil Tetracycline on Physiology and Biochemistry of Pea Seedlings

Figure 1

The general appearance of pea stipules from plants growing without tetracycline (a, b) or with 250 mg TC × L⁻¹ of perlite TC (c, d). The roots of control seedlings (e, f) and TC‐affected seedlings (g, h). Root and shoot lengths (i, j) after 24 () and 120 () hours of growth in soil supplemented with different tetracycline concentrations (0: control, 0.5, 1, 5, 10, 50, and 250 mg × L⁻¹ of perlite).
