Dauginimo būdų ir augimo stimuliatorių įtaka margalapės aktinidijos (Actinidia kolomikta) ‘Paukštės Šakarva‘ rizogenezei

Abstract

Investigation of the influence of growing conditions on Actinidia (Actinidia kolomikta) variety ‘Paukštės Šakarva‘ rhyzogenesis was conducted in 2015 at the Aleksandras Stulginskis University. Investigation was conducted using woody cuttings (took in the autumn and in the spring) and green cuttings (took in 27th of June). Cuttings were treated with solutions of IBA 0,025%, Universali trąša - stimuliatorius 0,2% and Aloe arborescens 10%. Aloe arborescens extract has the greatest positive impact on Actinidia cuttings rhyzogenesis, extract increased the number of regenerated roots and roots length, overall cuttings engraftment. Propagating Actinidia with green cuttings engraftment reaches 43.75%, while propagating with the woody stems only 8.33 - 18.75%, engraftment with green cuttings was substantially higher than with woody cuttings. Substantially the best rhyzogenesis recorded propagating with green cuttings using Aloe arborescens solution, 66.67% of cuttings regenerated roots, the average of regenerated roots – 5.88, the length – 28.46 mm.
