Study of the Physiological Dynamics of Cadmium Accumulation in Two Varieties of Rice with Different Cadmium-Accumulating Properties

Table 5

Cd content in grain under soil treatment with different Cd concentrations.

Rice organs	Soil treatment	Cd content (mg/kg)
		YZX	XWX
Grain	Cd-1	0.02 ± 0.00c	0.01 ± 0.00b
	Cd-2	0.04 ± 0.01b	0.02 ± 0.00b
	Cd-3	0.12 ± 0.00a	0.10 ± 0.01a
	Average	0.06	0.04

Note. Different letters indicated significant differences among soil Cd treatments. The differences among varieties at the level of 0.05, and a significant difference at 0.01 level.
