ABSTRACT A study was conducted to determine the effect of various antioxidants on seed deterioration of three soybean varieties stored under different types and periods of aging. The rates of seed deterioration of different varieties under varied aging conditions were also evaluated. The results showed that viability, and vigor (speed of germination, seedling growth rate) of all varieties decreased under all aging types over progressive aging, but the rates of decrease varied with variety and type of aging. Regression coefficients for viability over period of aging were highly significant with varieties exhibiting significantly different coefficients. Under any period of accelerated aging, no significant differences in viability nor vigor among seeds with or without antioxidant treatments were found. However under modified accelerated aging and natural aging conditions, viability and vigor of seeds.with antioxidants were significantly higher than seeds without antioxidant. Soybean seed viability and vigor were highly and significantly correlated with iodine vallue, peroxide value, and solute leachates under all aging conditions. INTISARI Penelitian dilakukan untuk melihat pengaruh antioksidant pada kemunduran tiga varietas benih kedelai yang disimpan pada kondisi penuaan yang berbeda. Kecepatan kemunduran benih dari tiga varietas dan kondisi penuaan yang berbeda juga dievaluasi. Hasil penelitian menunjukkan bahwa viabilitas dan vigor (kecepatan berkecambah dan kecepatan pertumbuhan benih) semua varietas menurun pada semua kondisi penuaan, tetapi kecepatan kemundurannya bervariasi pada tiga varietas dan tiga cara penuaan yang dicobakan. Koefisien regresi dari viabilitas terhadap periode penuaan menunjukkan hasil analisis yang sangat nyata. Pengaruh antioxidant dalam menghambat kemunduran viabilitas dan vigor kurang dapat dilihat pada penuaan yang dipacu/dipercepat, tetapi nyata terlihat pada modifikasi penuaan dan penuaan alami. Viabilitas dan vigor benih sangat nyata berkorelasi dengan 'iodine vallue', `peroxide value', dan 'solute leachates' pada semua kondisi penuaan. Key words : antioxidant, soybean, accelerated aging
