Elucidating the Role of Micronutrient Seed Treatment in the Physiological Performance of Wheat Seed

Seed treatment is one of the key techniques for improvement in physiological performance of seed lot in different crop plants. In the present study, the aim was to explore the technique in wheat, seed lot was treated with the different concentration of iron and zinc sulphate solution. Other method of micronutrient application was also adopted i.e., soil application and foliar spray at recommended dose. The micronutrient treatment with ZnSO4 (0.5, 2.0%) exhibit highest improvement in physiological parameters like root length, shoot length, seedling dry weight, standard germination, germination energy, germination rate, seed vigour index-I & II, dehydrogenase enzyme activity, membrane permeability i.e., EC and zinc & iron content in seed and plant in treated seed and harvested seed lot, respectively. Commonly seed treatment with ZnSO4 (0.5%) results in improvement of all the physiological parameters of treated seed as well as harvested seed.
