Evaluation of Biochemical Response to Zinc Stress in Cicer arietinum L
Abstract
The seedlings of Cicer arietinum L. grown in the hydroponic culture medium were administered three different concentrations of zinc (0.5, 1.0 and 2.0 mM) for 4 days and biochemical response was evaluated. Zinc induced stress triggered biomolecules positively at low concentration but most of the plants were susceptible to its toxicity at 2.0 mM. Except for chlorophyll and dry weight, all the other biochemical parameters such as total phenol, protein content, non-protein thiols and lipid peroxidation were found increased significantly as compared to control. The maximum increase or decrease was found to be at 2.0 mM zinc concentration.
