On the basis of conducted experiments on the rooting of dawn redwood cuttings it was found that the application of Seradix B No 1 mixed with Kaptan Zawiesinowy 50 (1:1, v:v) increased the number of rooted cuttings by 14.5% in comparison to the control. Moreover, an advantageous effect of the growth stimulator was observed on the number of secondary roots on a cutting. However, the application of a growth promoter did not have a marked effect on their length. Incision wounding of cuttings at their base had an adverse effect on the rooting percentage and the length of secondary roots. It results from the conducted observations that at the position of the incision wounding roots are not formed. It can be seen from the performed cross-section that dawn redwood regenerates roots from the cambium (cambial ring) and not from the callus. For this reason the labour-intensive procedure of incision wounding of cuttings is not recommended in the propagation of dawn redwood. The effect of two factors, i.e. incision wounding of cuttings and the application of a growth regulator, on the rhizogenesis process in dawn redwood was investigated in this study.
