Abstract: We studied the main factors with different levels for morphological after-ripening of Magnolia sieboldii seeds through repeated experiments with multi factorial. When the seeds of M.sieboldii were treated by soaking in the mixed solutions with 1.30-1.40 mg·L-1 6-BA and 2.00-2.20 mg·L-1 2,4-D for three days, mixing the seeds and sand (1∶4), with temperature change in 100-114 d, 18±2℃ and 8h in day, 7±2℃ and 16 h in night, the incidence rate of the heart-shape embryo was 97.8%, the incidence rate of the embryo with cotyledons was 95.6%, and the germination rate of seed was 98.0%. The morphological after-ripening of seed of M.sieboldii is suitable for industrial seedlings of M.sieboldii.
