AbstractToeterminethefetsofdferenthoronetypes，concentratiosandsakingtiesonthegerminationcharacteristsoftrus hongheensis seeds，an L9（34） orthogonal experiment was conducted.The germination dynamics were observed，and the germination rate，germinationpotetialandveragegerinatiotieerestatisiallalyd.Thesultsshowdthatthgeationrate，eatiootetial and average germination time of different treatment combinations were 31.11%-58.89% ， 21.11%-44.44% and 30.94-35.72 days，respectively. There were significant （ P<0.05 ）or extremely significant （ P<0.01 ）differences among the 9 treatment combinations. The optimal germination index（characteristic） was obtained when seeds were soaked in a mixed solution of 0.20g/L （20 GA3 and 0.30g/L IBA for 8 hours.

Soaking seeds in a mixed solution of 0.20g/L （2 GA3 and 0.30g/L IBA for 8 hours improved the germination characteristics of Citrus hongheensis seeds.It is recommended as a treatment measure for seed germination in the propagation of Citrus hongheensis seedlings.
