Variations in the cadmium (Cd) accumulation and root characteristics of different genotypes rice during three developmental periods dry cultivation were investigated pot experiments which two levels Cd added to soil (0 10 mg kg−1). The results show that concentration each organ decreased both order roots > shoots grains maturity stage booting tillering stage. lowest bioaccumulation factor (BCF) translocation (TF) found Yunjing37 (YJ37) under stress. At maturity, stress inhibited length Dianheyou34 (DHY34) most Dianheyou 918 (DHY918) least, also affecting volume DHY34 Dianheyou615 (DHY615) YJ37 Yiyou 673 (YY673) least; inhibition rates 41.80, 5.09, 40.95, 10.51%, respectively. exodermis showed greatest thickening YY673 DHY615, while endodermis opposite result. change 16.48, 2.45, 5.10, 8.49%, stele diameter DHY615 most, secondary xylem area result; −21.50, −14.29, −5.86, −26.35%, Under treatment at iron plaque was extracted using dithionite–citrate–bicarbonate (DCB) method.
