The focus of the review is on the specific aspects of Ni and Zn effects on growth morphology, Biochemical activity/responses, mineral nutrition and enzyme activity of plants. The quantity of Ni required for normal growth and development of plant is very low. Ni has been identified as a component of various enzymes in plants, various other biochemical, physiological and growth responses. The concentrations of Ni and Zn in the environment are currently increasing due mainly of human activities. Zn and Ni are essential elements for several biochemical processes in plants. At high concentration in soil, can cause severe damage to physiological and biochemical activities of plants. The higher concentration of Ni is associated with soils, plants chlorosis and inhibits, root and shoot growth. Excess of Ni inhibits a large number of enzyme and including photosynthesis; pigments synthesis.

 

Keywords: Biochemical constituents, Heavy Metal, Nickel, Zinc.
