3-weeks old Commelina was transferred to and grown in Hoagland solution (Control, $100muM$ $Cd^{2+}$, $100muM$ $Cd^{2+}$+ $100muM$ IAA, $100muM$ $Cd^{2+}$+ $100muM$ IAA + 2 mM sucrose) for 3 weeks and then the effects of indole acetic acid (IAA) on the accumulation of $Cd^{2+}$ and growth of $Cd^{2+}$-treated Commelina were investigated. In the treatment of $Cd^{2+}$, $Cd^{2+}$ was uptaked to 1.74, and 51.36 ${mu}g/g$ frwt. at the first week, but for three weeks, 0.51 and 34,53 ${mu}g/g$ frwt, in leaf and stem respectively. When IAA was treated along with $Cd^{2+}$, $Cd^{2+}$ was uptaked to 0.18 and 8.63 ${mu}g/g$ fiwt, at the first week, and for the incubation of 3 weeks, 0,51 and 45.0 ${mu}g/g$ fiwt. in leaf and stem. In case of $Cd^{2+}$+IAA+sucrose, $Cd^{2+}$ was uptaked to 1.45 and 18.33 ${mu}g/g$ frwt. at the first week, but for 3 weeks, 0,51 and 25.45 ${mu}g/g$ fiwt. in leaf and stem. Likewise $Cd^{2+}$ uptake, the growth was also affected by $Cd^{2+}$ and IAA. During the incubation of 3 weeks, $Cd^{2+}$ reduced the stem growth about 8% in all weeks, but the treatment of IAA recovered the inhibition of stem growth caused by $Cd^{2+}$ to the degree of the control Therefore, it could be concluded that IAA altered the pattern of $Cd^{2+}$ uptake and the growth which were supposed to change $Cd^{2+}$ toxicity.
