This research was performed to compare Pb and Cd accumulation in root and leaves of pinus brutia. The effects of these elements in different concentrations (0, 200, 500 and 1000) on the amount of proline, soluble sugar of the plant were also investigated. The experiment was done in a factorial design in three replicates. The concentration of Pb and Cd in leaves and root were measured by atomic absorption. The proline and soluble sugar were measured by Bates and Kochert method, respectively. Results showed that the Pb did not have any effects on poline concentration in pinus brutia. In contrast, Cd increased the amount of proline especially in concentration of 500 ppm. Cd did not affect the amounts of soluble sugar but Pb relatively increased this compound. Accumulation of Cd in root and leaves of the plant increased by increasing Cd and Pb concentration. It is concluded that proline may play a role in Pinus brutia Cd tolerance. Soluble sugar may not play an important role to increase the tolerance of the plant. It is also concluded that for a high Cd accumulation in root, Pinus brutia can be used as a phytostabilization in Cd and Pb polluted soils.
