摘要：Mercury poisoning has become a problem of current interest as a result of environmental pollution on a global scale. Natural emissions of mercury form two-thirds of the input, and man-made releases form about one-third. Considerable amounts of mercury may be added to agricultural land with sludge, fertilizers, lime, and manures. The most important sources of contaminating agricultural soil have been the use of organic mercurial as a seed-coat dressing to prevent fungal diseases in seeds. In general, the effect of treatment on germination is favorable when recommended dosages are used. Injury to the seed increases in direct proportion to increasing rates of application. So an attempt was made on the impact of different concentrations of mercury on certain varieties of green gram (Vigna radiata L). Green gram was irrigated different concentrations of mercury. After on week exposure the seedlings were used for the morphological (seed germination, seedling growth, seedling fresh and dry weight) and biochemical estimations (chlorophyll, protein, amino acids and sugars). All the morphological and biochemical parameters are gradually decreased with the increase of mercury concentrations.
