Rozmnażanie wegetatywne derenia jadalnego (Cornus mas L.) przez sadzonki półzdrewniałe

Softwood cuttings of cornelian cherry were rooted in the mixture of high moss peat and perlite with pH 5.0, in a polyethylene foil tunnel with automatic mist system placed in unheated greenhouse. Two-nodded, sub-apical, 10–12 cm long soft-wood cuttings were obtained from mother shrubs of several dozen years old. They were treated or not with Rhizopon AA containing 1% auxin IBA. Bases of cuttings were wounded or not. Application of Rhizopon AA was essential for the rooting of the cornelian cherry. Cuttings not treated with auxin did not produce adventitious roots. Wounding of cuttings decreased rooting efficiency. Rooting efficiency of cornelian cherry was also influenced by genotype.
