Margalapės aktinidijos (Actinidia kolomikta Maxim.) dauginimas žaliaisiais auginiais

Abstract

Actinidia (Actinidia kolomikta Maxim.) shoots in 2013 was cuting Aleksandras Stulginskis University Pomology garden. Were tested three varieties ‘Paukštės Šakarva’, ‘Lankė’ ir ‘Landė’. In order to evaluate genetic, physiologic and physical factors influencing rhizogenesis of soft cuttings of actinidia, cuttings from three cultivars were taken at the beginning of lignification. It was estimated, that the IBA solution, compared with the control slightly increases the yield of cuttings with roots. IAA efficiency is not significantly different from the IBA. Cuttings with the lowest lignification level, wich were taken from terminal shoot part, regenerated roots more intensively. The length of cutting is crucial from the rhizogenesis of actinidia cuttings. Minimal cutting parameters for potential rhizogenesis are shown. Rate of rhizogenesis increase in longer cuttings.
