Effects of aeration or/and 50 μM CdCl2 treatments on the structure of rice root. a Transverse section at 0.5 cm from root apex, bar indicates 100 μm; b Transverse sections of root at 1 cm from root apex, bar indicates 100 μm; c Diameters of roots at 0.5 cm and 1 cm from root apex. The 3-week-old rice seedlings under hydroponic culture were aerated with air pump (30 min per hour) in the absence or presence of 50 μM CdCl2 for 14 d. The values are means ± SE (n = 5). Different letters on bar indicate significant differences at P < 0.05
