Mini-cuttings were 4 ± 1 cm in length, with the bases immersed in solutions of 0, 1000, 2000, and 3000 mg L-1 IBA. They were then planted in polypropylene tubes using two substrates (vermiculite and Tropstrato®) and maintained under greenhouse conditions for 60 d. The experiment was carried out with a 2 x 4 factorial scheme (substrates x IBA). There was no influence of IBA application on the promotion of rhizogenesis in Ginkgo biloba mini-cuttings. The rooting percentages were higher than 55% regardless of the treatment used. The vermiculite substrate showed a higher number of roots (4.94) and lower mortality (11.60) of mini-cuttings than Tropstrato®. We conclude that the mini-cutting technique is feasible for Ginkgo biloba, and the use of IBA is not necessary. We found that the induction of adventitious rooting depended on the biochemical composition of the mother plants, due to the translocation of non-reducing sugars and leaf proteins for root formation. 2020 artículo científico 0120-9965 https://www.redalyc.org/articulo.oa?id=180376042014 https://www.redalyc.org/journal/1803/180376042014/ https://www.redalyc.org/journal/1803/180376042014/html/ https://www.redalyc.org/journal/1803/180376042014/180376042014.epub https://www.redalyc.org/journal/1803/180376042014/movil 10.15446/agron.colomb.v38n3.86430 en http://www.redalyc.org/revista.oa?id=1803 Agronomía Colombiana application/pdf Universidad Nacional de Colombia Agronomía Colombiana (Colombia) Num.3 Vol.38 |
