摘要
This study aimed to investigate the effects of different cutting facilities, cutting time and hormone treatments on the sumval and rooting of Plumbago au- riculata summerwood cuttings. The results showed that a new type of cutting facility used in this study significantly improved the survival rate of P. auriculata sum- merwoed cuttings ; the best time for summerwood cutting of P. auriculata was May; various hormone treatments significantly improved the rooting rate of P. auricu- /ata summerwood cuttings; the optimal concentrations of NAA, IAA and IBA were 1 000, 1 500 and 1 500 mg/L, respectively. This study provided scientific basis for the establishment of summerwoed cutting propagation technology system of P. auriculata.
