英文摘要	Cadmium (Cd) is a widespread and toxic heavy metal that is a threat to plant, animal and human health. Phytoremediation, the use of tolerant species for the remediation of polluted areas, is a green technology that can be used for environmental pollution control. This pot study was conducted to evaluate the effect of soil Cd on growth, irrigation-water use efficiency, and Cd uptake, translocation and accumulation in Barbados nut under different irrigation regimes. Barbados nut was grown at low (50 mg kg(-1)), medium (100 mg kg(-1)) and high (200 mg kg(-1)) Cd levels as well as with no Cd under four irrigation regimes: 30, 50, 70 and 90% of soil water-holding capacity (SWC). Moreover 50% soil saturation percentage was considered as 100% SWC. The results revealed that the growth and dry matter accumulation of Barbados nut decreased with increasing soil Cd levels; however, this decrease declined with increasing irrigation amounts. In addition, Cd accumulation in different tissues was found to be in the order of root > stem > leaf, and excess soil Cd supply might inhibit Cd transportation from root to canopy. The higher dry matter accumulation, Cd accumulation, bioconcentration factor and irrigation-water use efficiency were observed at 50 similar to 70% SWC and low Cd levels (50 mg kg(-1)). Moreover, Barbados nut survived under severe drought (30% SWC) and the highest soil Cd concentrations (200 mg kg(-1)), exhibiting a strong capacity to resist drought and Cd stress. In conclusion, Barbados nut plants can be used for the phytoremediation of Cd-polluted soils in arid regions (C) 2020 Friends Science Publishers
