Figure 1. Microscopic observation of the transverse section of leaves (×400, bar = 100 µm). Beet plants were treated with different concentrations of Boron (T1, 0.05 mg/L; T2, 0.5 mg/L; T3, 2 mg/L; T4, 30 mg/L) for 30 days. The representative images are shown (N = 10, from independent plants). UE, upper epidermis; PT, palisade tissue; ST, spongy tissue; LE, lower epidermis

Figure 2. Microscopic observation of chloroplasts in beet leaves by transmission electron microscope (× 4000, bar = 10 µm). Beet plants were treated with different concentrations of Boron (T1, 0.05 mg/L; T2, 0.5 mg/L; T3, 2 mg/L; T4, 30 mg/L) for 30 days. The representative images are shown (N = 5, from independent plants). For analysis of chloroplasts, five images from five independent plants were used (five cells for each image)
