| Abstract:
Cutting is one of the principal propagation methods of kiwi plants (Actinidia sp.). The paper presents some new aspects of the basal heating techniques on hardwood cuttings rooting. Cuttings of Actinidia deliciosa and Actinidia arguta varieties and selections were treated with alpha naphtyl acetic acid (2,000 - 3,000 ppm). Composed rooting substrates, double layers and mixed, with: 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 specie, variety, cutting moment, substrate type used and basal and atmospheric temperature. | |
