Stimulation of adventitious root formation by laser wounding in rose cuttings: A matter of energy and pattern.

ABSTRACT: Adventitious root (AR) formation is the basis of vegetative propagation in rose, be it via stem cuttings or via stenting. During this process, wounding plays a pivotal role since cell reprogramming takes place at the tissue adjacent to the wound. We investigated the effects of wounding on AR formation on leafy single-node stem cuttings of the rose rootstock R. canina 'Pfänder' (codes R02-3 and R02-6) and the cut rose cultivar Rosa 'Tan09283' (Registration name 'Beluga'). Laser wounding treatments were based on the assisted removal of tissue layers located in the bark. The positioning of wounding was studied based on two marking directions: along the cutting base (strip pattern) and around the cutting base (ring pattern). Additionally, the effects of external sup
