Abstract
The pot-culture experiment and field studies were conducted to screen out and identify cadmium (Cd) excluders from 40 Chinese cabbage genotypes for food safety. The results of the pot-culture experiment indicated that the shoot Cd concentrations under three treatments (1.0, 2.5 and 5.0 mg Cd kg(-1) Soil) varied significantly (p<0.05), with average values of 0.70, 3.07 and 5.83 mg kg(-1), respectively. The Cd concentrations in 12 cabbage genotypes were lower than 0.50 mg kg(-1). The enrichment factors (EFs) and translocation factors (TFs) in 8 cabbage genotypes were lower than 1.0. The field studies further identified Lvxing 70 as a Cd-excluder genotype (CEG), which is suitable to be planted in low Cd-contaminated soils (Cd concentration should be lower than 1.25 mg kg(-1)) for food safety.Entities:
