| Abstract:
Use of cutting can be an efficient propagation method for Prunus rootstocks. Some new released Romanian Prunus rootstocks: ‘CPC’, ‘CT169’, ‘C5’ (Prunus cerasifera) and ‘Otesani 11’ (Prunus insititia) were compared with some well known rootstocks: ‘Myrobalan 29C’ (Prunus cerasifera), ‘Pixy’ (Prunus insititia), ‘Myran’ and ‘Ishtara’ (Prunus hybrids) on the rooting ability. The hardwood cuttings were treated with alpha naphtyl acetic acid (3000 ppm). Composed rooting substrates, double layers: wood flour + perlite; wood compost + perlite and cotton waste + perlite were used. Hot water was used as heating agent in a closed circuit. The rooting percentage and the quality of formed roots were strongly influenced by species, varieties and substrate type. | |
