Abstract: The tissue culture can contribute to the propagation of several economic species, such as the bromeliads. This research aimed at evaluating the auxins type and concentration in the in vitro and ex vitro rhizogenesis of Neoregelia concentrica bromeliad. N. concentrica shoots were induced in a growth medium with 15.0 µM of 6-benzylaminopurine, for 80 days, followed by sub-cultivation in phytoregulator-free medium, for 45 days. In the in vitro rhizogenesis, the shoots grew in a medium supplemented with indole-3-b… Show more

“…Micropropagation procedures for bromeliads have frequently been published (Martins et al 2013(Martins et al , 2014Mengesha et al 2013;Kurita and Tamaki 2014). Most of these studies are related to the use of plant growth regulators, temperature, carbon source or mineral composition of the culture medium being the main modulators of in vitro morphogenetic responses.…”

“…The improvement of in vitro rooting techniques allows for easier and faster adaptation and helps in better survival of plantlets under ex vitro conditions (Krupa-Małkiewicz and Mgłosiek 2016). The application of auxins to in vitro cultures accelerates root formation and enhances rooting rate (Martins et al 2013;Miri and Roughani 2018a). In the present study, the type and concentration of exogenous auxins influenced the average number of roots produced per explant as well as the mean length of the roots.…”

“…In our experiment, we even observed rooting in the multiplication phase with lower BA concentrations. This is probably due to the endogenous concentration of IAA in the shoots of ginger that moves to lower parts and its concentration increases at the basal end of the shoots where it stimulates root formation or provides an appropriate hormonal balance along with other exogenous auxins to improve rooting (Martins et al 2013). The highest number and length of roots were observed in the media supplemented with IBA at higher concentrations (2 mg/l).…”

“…Studies on the in vitro culture of bromeliads reported by Droste et al (2005), Huang et al (2011b), and Martins et al (2013Martins et al ( , 2014 have shown that this technique is important for the multiplication of species belonging to this family.…”
