A pot experiment was conducted to study the differences of uptake and translocation of Cd and Pb in four water spinach cultivare, including two low-Cd-Pb cultivare and two high-Cd-Pb cultivars. The results showed that the characteristics of low-Cd-Pb and high-Cd-Pb accumulation were stable in the two types of cultivars, respectively. The differences in shoot Cd concentration between low-Cd-Pb and high-Cd-Pb cultivars were attributable to the differences of Cd uptake and translocation from root to shoot, but the differences of shoot Pb concentration appeared to be driven by whole-plant Pb uptake rather than by Pb translocation from root to shoot.

Changes in soil properties during long-term planting require thorough study. The objectives of this study were to determine the influence of planting Caragana microphylla on grassland on soil carbon, nitrogen, and phosphorus to a depth of 20 cm along a 34-year chronosequence encompassing 10 plantation-age groups in northwest, China. We found soil organic carbon increased by -21.84%, 0%, and 39.09% in planting years 5, 21, and 34, respectively. Total nitrogen and total phosphorus began to change in the plantation years 9 and 7, and increased by 70.59% and -28.26% in year 34. Both available nitrogen and available phosphorus increased across the chronosequence. The results indicate that the processes of changes in soil carbon, nitrogen, and phosphorus are different in a long-term chronosequence, and that Caragana microphylla has potential to improve soil properties after it is planted on grassland.
