Abstract:
Six different concentrations of chitosan and five different concentrations of cadmium were selected and studied to determine the optimum concentration of chitosan for remediating cadmium toxicity through seed application. Results revealed that the morphological parameters (germination%, root length, shoot length, seedling vigour index, fresh weight and dry weight of seedlings) differed significantly among treatments and genotypes. Lower concentrations of chitosan (0.1% and 0.2%) were more effective in mitigating cadmium toxicity than higher concentrations in pea genotypes in terms of parameters studied as above. Chitosan mitigated adverse effects of cadmium in both the selected pea genotypes. The Cd 200 µM concentration was most detrimental for both the genotypes. Based on our results, we conclude that chitosan with lower concentrations has significant positive effects on all the parameters in response to cadmium toxicity and proves to be an important aspect for remediation of cadmium toxicity.
