Abstract:
This study attempted to evaluate the response of lead on different varieties (HUM 1, HUM2, HUM6, HUM12 and HUM27) of Mung bean (Vigna radiata). Mung bean seeds were soaked in lead nitrate solution [Pb (NO₃)₂] of concentrations of 0 mM, 0.25 mM and 0.50 mM for 2 hours. Chlorophyll pigments, Proline content and Malondialdehyde content was estimated on the 14th day of early seedling stage. It was found that Chlorophyll pigments of Mung bean seedling significantly decreased with the increase in concentration of lead nitrate. However, a proportionately increased amount of proline and malondialdehyde content was observed with increasing concentration of lead nitrate. All the varieties of Mung bean responded differently to the lead nitrate concentrations. HUM 2 and HUM 6 were found to be more sensitive as compared to other varieties.
