| Abstract |
A 65-day field experiment was conducted to select cadmium (Cd)-safe genotypes (CSGs) among 21 Chinese cabbage genotypes in a low Cd-contaminated soil (0.66 mg kg(-1)). Seven CSGs were identified based on their Cd tolerance, shoot Cd concentrations, Cd enrichment factors (EFs), and translocation factors (TFs). Then, Beijingxin3, a typical CSG, together with Qiuxiang, a typical non-CSG for comparison, was selected for a subsequent 80-day field micro-plot experiment under four levels of Cd stress to evaluate the reliability of CSG screening and the role of organic acids in Cd accumulation and tolerance. Beijingxin3 was confirmed to be safe to grow in soil with Cd level up to 3.39 mg kg(-1), with Cd accumulation in its shoots well below the permitted level, and Qiuxiang was still poor in tolerating low Cd stress (1.31 mg kg(-1)). With increasing the Cd stress, Cd accumulation and citrate concentrations increased in shoots and roots of both genotypes, and oxalate concentrations increased significantly in Beijingxin3 roots. Both oxalate and citrate concentrations were significantly positively related to Cd accumulation for Beijingxin3 roots. High accumulation in oxalate and citrate induced by Cd stress in Beijingxin3 roots could benefit its internal tolerance to long-term Cd stress with more Cd accumulation in its roots and less Cd accumulation in its shoots. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 June 2016.
All research outputs
#21,420,714
of 23,911,072 outputs
Outputs from Environmental Science and Pollution Research
#7,000
of 9,883 outputs
Outputs of similar age
#226,611
of 267,333 outputs
Outputs of similar age from Environmental Science and Pollution Research
#113
of 171 outputs
Altmetric has tracked 23,911,072 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,883 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,333 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 171 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
