The present study was conducted to develop seed treatment for the production of healthy and clean peanut sprout. Dry heat treatment of peanut seeds reduced the incidence of the rot. The seed treatment condition at 52℃ for 10 h. was the most efficient without inhibiting seed viability significantly. Seeds were dark cultured at 27℃ for up to 9 days. The treatment of Indole-B and gibberellic acid influenced germination, T50, fresh, dry weight, hypocotyl length, hypocotyl length diameter, root length, number of lateral root and epicotyl of peanut sprout. There were no differences in the germinability of peanut seeds between gibberellic acid treatment methods but higher fresh weight was observed in the GA3 solution spray after 2 hour water soaking. The general growth and lateral root development of peanut sprouts were suppressed by Indole-B which is used for inhibiting root formation and promoting hypocotyls. The treatment of gibberellic acid promoted hypocotyl elongation, but it did not influence on the growth of hypocotyls and root system.
