The heavy metal (Ni, As, and Al) is one of the most important cause of stress in the environment. The aim of this study was the investigation the effect of nickel nitrate on some of morphological and biochemical properties in coriander (Coriandrum sativum L.). The experiment was conducted as a randomized complete block design with four replications in Damghan University, Iran. Treatments included 0, 100, 200, 500 µM nickel in hogland dietary solution. After two weeks of treatment, the plants were harvested for necessary tests. Results of variance analysis showed that increasing nickel concentration reduced the dry weight root and shoot as well as root and shoot lengths. The results of biochemical parameters demonstrated significant reduction in chlorophyll (a and b) and protein content, but the amount of soluble sugars, anthocyanins, proline and carotenoid increased significantly. Also, with the increasing of nickel levels, nickel accumulation increased both in shoot and root; as a result, a large amount of nickel was accumulated in the roots to shoots. The results indicated that the accumulation of nickel was more in the root than aerial parts (transmission ratio less than 1), and therefore cannot be regarded as a storing plant.
