Cadmium is a potentially toxic metal and thus its transfer from plants to humans is of great concern. This heavy metal is ranked number seven among the top toxins, mainly due to its negative influence on the cells enzymatic systems. In the present study influence of different concentrations of cadmium nitrate (0.07% and 0.15%) either, alone or in combination, with mycorrhiza and different concentrations of putrescine in maize was observed. The present study was carried out to evaluate the compatibility of polyamines (putrescine) and mycorrhiza in the mitigation of induced toxic effect of cadmium at 30, 60 and 90 DAS of Rabi maize variety BIO-9544. Biochemical observations were recorded at 30, 60 and 90 days after sowing. Leaf samples were collected from all the leaves and mixed for taking the required quantity of sample for estimation. The treatment T17 was found to show better results; significant increase in total soluble sugar content by 4.22%, 5.03% and 4.18% with respect to T12 was observed. Similarly in the case of total soluble protein, the treatment T17 was found to show better results; significant increase in total soluble protein content by 39.57%, 21.53% and 19.71% with respect to T12 was observed. So, the combination of putrescine and mycorrhiza showed the best combination for the mitigation of cadmium toxicity for the total soluble sugar and total soluble protein content. Based on the results, it is concluded that the application of putrescine (2.5mM and 5.0mM) and mycorrhiza and their interaction were more effective in increasing the physiological and biochemical attributes in maize against Cd induced stress.
