| Abstract: | Using stem-segments of Photinia fraseri'Red Robin'as explants,in vitro culture and rapid propagation were studied.The results showed that the suitable medium for bud induction was MS+BA 1.5 mg/L+NAA 0.2 mg/L,the optimum subculture medium was MS+BA 1.0 mg/L+IBA 0.1 mg/L+NAA 0.1 mg/L,on which each explant produced up 3.0 plantlets on the average.The cutting were immersed with 500 mg/L IBA for 10 s and used peat as medium,the frequency of rooting reached 94.2%. |
