The efficiency of pre—sowing treatment of Magnolia grandiflora seeds with GA3 and/or IAA at different concentrations (1000, 1500, 2000 and 2500 ppm) was investigated. The highest germination percentage was obtained with 2500 ppm GA3 or lAA+GA3 (66.25%, 62.50%, respectivety). Meanwhile, lAA with or without GA3 induced the best seedling growth. Using of 2500 ppm GA3+lAA is, therefore, recommended to attain high germination percentage and vigorous seedlings.
