The Use of Spectroanalytical Techniques in Detecting the Heavy Metal and Salinity in Solanum tuberosum (cv. Kufri Bahar) During Indoor Study
The vegetable crops are getting most affected by exposure to rising concentrations of heavy metals and salinity in soil all over the world. Their accumulation in such plants can be analyzed by sophisticated techniques for further studies. Atomic absorption spectroscopy (AAS) is very popular spectroanalytical technique used to quantify nearly seventy different elements in solution or directly in solid samples. The flame photometry is used to estimate the Na (sodium) in plants as marker of NaCl level. The indoor growth of the Solanum tuberosum was done to check the effects of Cd and salinity in roots and shoots. The nutrients are provided into Hoagland’s solution. The regimes of cadmium, sodium and combination of both stresses were chosen. The cadmium accumulation increased all over the plant but highest level in root was at 2 mM Cd given without NaCl. Root Na increased with increase in external NaCl irrespective of Cd. But, shoot Na levels behaved differently because Na increase peaked at 50 mM NaCl when given individually but increase was continuous when NaCl was given in presence of cadmium. AAS and flame photometry aided in getting a clear picture of Cd and Na accumulation in potato plants.
