Abstract: The effects of different auxin ( IAA, NAA and IBA) , phloroglucinol, culture in dark, paclobutrazol (MET) and supportingmaterials on Photinia fraseri rooting were studied. The results showed that NAA 0.5 mg·L ^{- 1} and culture in dark for 7 days promoted rooting through orthogonal experiment; and when the 1 /2MS +NAA 0.5 mg·L ^{- 1} + IBA 0.3 mg·L ^{- 1} +MET 0.5 mg·L ^{- 1} medium induced rooting, mean number of roots was 6.5, rooting rate was 90%. Besides, the effects of agar, veimiculite and pearlite as supporting materials were studied. Pearlite was the best supporting material; mean number of roots was 23.8; rooting rate was 9616%; the survive rate of transplant seedlings reached 95.9%; root vigor reached 576.159μg·g^{- 1} ·h^{- 1} ; POD activity reached 27.08 △A₄₇₀ ·min^{- 1} ·g^{- 1}.
