摘　　要：以红叶石楠‘红罗宾’的茎段为外植体建立再生体系。结果表明:适宜的诱导培养基为MS+BA 1.5 mg/L+NAA 0.2 mg/L;增殖培养基为MS+6-BA 1.0 mg/L+IBA 0.1 mg/L+NAA 0.1 mg/L,增殖系数可达3.0;红叶石楠瓶外生根适宜的方案为:以草炭土为基质,插条在500 mg/L的生长素中浸泡10 s,生根率可达94.2%。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 re_g/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%.
