Impact of Low Boron Treatment on Germination Capacity, Membrane Permeability and Antioxidant Machinery in Soybean Seeds

To detect the boron deficiency induced changes in germination capacity and seed quality an experiment was conducted on soybean (Glycine max var.JS-335) plants.For this soybean plants were grown till maturity at deficient (0.033 mg L-1) and sufficient (0.33 mg L-1 ) boron supply.Seed yield was determined at 112d when plants were harvested.To study the effect of low boron concentration on seed quality-concentration of carbohydrates (sugars and starch), phenols, proteins and oil content were determined in the post harvested seeds of soybean.Membrane permeability was determined by the electrical conductivity and MDA content in seeds.Antioxidant responses of seeds were studied by estimating the parameters of CAT, PPO and POD enzymes.
