摘　　要：以玉竹种栽为试材,研究0、25、50、75mg/L等4个浓度生根粉对其地上部、新生根茎生长的影响。结果表明:使用25～75mg/L ABT处理种栽,对玉竹新生根茎数量的增加和产量的提高有明显的促进作用。其中以50mg/L效果最好,可比对照增产20.6%～46.6%。产量的提高主要是通过增加根茎的数量实现的。ABT处理对出苗有一定的促进作用,对株高与叶片数影响不明显。Taking Polygonatum odoratum（Mill.） Druce as experiment materials,the effects of rooting powder with 0,25,50 and 75 mg/L four different concentrations,on the growth of its overground part and newly grown rhizome were studied.The results showed that the production and the number of the newly grown rhizome of Polygonatum odoratum（Mill.） Druce could be increased significantly by treating the seeds with ABT of the concentration of 25~75 mg/L.Soaking the seeds with ABT of the concentration of 50 mg/L showed the most obvious results.The production was increased by 20.6%~46.6% compared to the control group.The increase in production was mainly achieved by the increase in the number of rhizome.To some extent,ABT could help increase the germination rate.But its effect on plant height and the number of leaves was not obvious.
