摘　　要：以兰州百合为试材,采用单因素随机区组设计和正交设计,研究了NAA、IAA、IBA、6-BA、2,4-D、GA36种植物生长调节剂及6-BA、NAA、2,4-D不同浓度配合对其鳞片扦插繁殖小鳞茎的影响。结果表明:植物生长调节剂能促进兰州百合鳞片扦插繁殖小鳞茎。180d后,200mg/L IBA处理的百合鳞片扦插繁殖系数最高,达到5.50,比对照高153.46%。综合分析,在激素配合处理中,6-BA 20mg/L+NAA 200mg/L+2,4-D 30mg/L处理,繁殖系数最高,平均为2.20;6-BA10mg/L+NAA 100mg/L+2,4-D 20mg/L处理,生成的小鳞茎重量最大,平均为1.83g/瓣,生产量最高,为3.16g/个。Taking Lilium davidii var. unicolor as materials, using single factor randomized block design and orthogonal design, the influence of different concentrations of NAA, IAA, IBA, 6-BA, 2,4-D,GA3 and 6-BA, NAA, 2,4-D cooperate on scale cutting propagation of Liliurn davidii var. unicolor were studied. The results showed that plant growth regulators could promote scale cutting propagation of Lilium bulblets. After 180 days, the treatment of 200 mg/L IBA, the propagation coefficient was the highest and reached 5. 50,it was higher （153. 46 ~） than CK. Consider comprehensively. In all of hormone cooperating,the combination genetrated the biggest propagation coefficient was 6-BA 20 mg/L＋NAA 200 mg/L＋2,4-D 30 rag/L, the propagation coefficient was 2. 20. The combination genetrated the biggest quality and production of bulb was 6-BA 10 mg/L＋NAA 100 mg/L＋2,4-D 20 mg/L,the biggest quality was 1.83 g each one bulb and production was 3. 16 g each scale.
