The Influence of Laser Beam and Auxins on Rooting of Leatherleaf Viburnum (VIBURNUM RHYTIDOPHYIIUM Hemsl.) Cuttings

The aim of this work is to compare the effect of three- and sixfold irradiation with a semiconductor laser beams of 200 mW power and wavelength equal to 670 nm and the rooting agent on the percentage and quality of rooted cuttings of leatherleaf viburnum. The most effective for root number and root length was threefold irradiation and for fresh root weight threefold irradiation applied together with the rooting agent.
