To evaluate the efficiency of zinc and cadmium on the Fe and Cu uptake and some physiological indices in Trifolium Alexandrinum, an experiment was carried out using Factorial Design based on Randomized Blocks with four replications. The experiment factors included four levels of Cd (0, 25, 50, 100 mg/kg soil) and four levels of zinc (0, 25, 50, 100 mg/kg soil) in greenhouse conditions in Agriculture and natural resource faculty greenhouse located in Mola Sani 40 km north of Ahwaz in 3 November 91-92 . Carmel variety was used in this study. The results showed that Cd consumption on leaf area index (P<0.01), and dry matter (P<0.05) was significant leading to a reduction in the content of all these elements. The results also showed that applied Cd had significant effect on the Fe and Cu concentration in plant tissues, too. Cd application decreased Fe concentration to 22.08 mg/kg and Cu to 4.47 mg/kg in shoot and leaf. The zinc application increased leaf area index and dry matter in significant level. With Zn application separately, the amount of Fe and Zn decreased by 14.28 and 3.36 mg/kg in shoot and leaf, respectively.
