The present study was aimed to evaluate the uptake and dry weightresponse of vetiver grass (Vetiveria zizanioides L.) subjected to different levels of cadmium(Cd) (0, 3, 6 and 12 mg/kg soil) and nickel (Ni) (0, 50, 100 and 200 mg/kg soil) stress. Theexperiment was conducted in pots using a completely randomized design with fourreplications for three months. Concentration of Ni and Cd was determined using atomicabsorption spectrophotometer. The dried weight of aerial and underground parts of Vetivergrass individuals at the end of the experiment were used to compare plant weight responseto different stresses. Statistical analysis was performed using version 18 of SPSS softwareand analysis of variance (ANOVA) and mean comparisons were completed through Tukeymethod. No restrictions on Cd uptake was observed in root and shoot of Vetiver grass, butin the case of Ni, its concentration in shoots of vetiver grass decreased with higher metallevels.The highest transfer factor (TF) among Ni treatments was observed at the lowestconcentration (50 mg/L) and the highest TF among Cd treatments was observed at thehighest concentration (12 mg/L). Results revealed that Ni and Cd had a significant (p<0.05)positive effect on shoot and root dry weight of Vetiver grass. Our results suggest capabilityof this plant for use in phytoextraction of Ni and phytostabilisation of Cd contaminatedsoils.}, keywords = {Contamination,Dry weight,Heavy metals,Remediation,Translocation factor 1}, url = {https://ijerr.gau.ac.ir/article_4146.html}, eprint = {https://ijerr.gau.ac.ir/article_4146_e5e936c23295415a2ccc741e6a46dd32.pdf} }
