Biomass of G. parviflora in the pot experiment.

Plants were cultured in soil containing 10 mg added Cd (kg soil)−1 for 50 d. Values are means (±SE) of three replicate pots. Different lowercase letters within a column indicate significant differences based on one-way analysis of variance in SPSS 13.0 followed by the least significant difference test (PBiomass of G. parviflora in the pot experiment.
