97799The effect of elevated concentrations of fungicide Topsin-M on nucleic acid, amino acid and phenols of Cicer arietinum L. was studied. Topsin-M was applied to Cicer arietinum L. foliage at seedling and at fruiting stage. It was observed that nucleic acid (DNA and RNA) contents of the crop decreased, while amino acid and phenolic contents increased as a result of such foliar application of Topsin-M. We found that amino acids such as glycine, asparagines, alanine, methionine, phenyl alanine were present both in control and treated plants, while cystein, proline, tryptophane and valine contents were found in higher quantities in treated samples as compared to control ones. Reduction in nucleic acid, changes in amino acids and an increase in total phenolic contents were significantly higher when higher concentration of fungicide was applied to the crop.
