Summary: | Abstract
The work is focused on enhancement of in vitro propagation technique of valuable
Lonicera caerulea
L. cultivars. The impact of some nutrient medium components at main cultivation stages of the genus
Lonicera
L. representatives was studied. Some cultivars showed the positive effect of substituting sucrose for glucose in the medium at the multiplication stage (Diana (30 or 40 g L
−1
), Moskovskaya 23 (20 g L
−1
) and Yugana (40 g L
−1
)). When studying the influence of different auxin types on honeysuckle rhizogenesis, Solovey and Yugana preferred addition of 1.0 mg L
−1
IBA into the medium. During the research of influence of different auxin concentrations on
L. caerulea
rooting the increased number of rooted microshoots of Goluboy Desert was demonstrated with the increasing of IAA concentration (from 0.5 to 3.0 mg L
−1
). Meanwhile, Diana and Yugana better rooted on the medium containing 1.0 mg L
−1
IAA but Zolushka reached its highest rooting percentage on the medium supplemented with 0.5 mg L
−1
IAA. The assessment of second-year plants undergone the whole cycle of clonal micropropagation was carried out 85% of these plants began to bear fruits. |
