    Opis:
    Mandevilla sanderi is an important commercial ornamental pot plant. Traditional vegetative propagation is limited due to the low rate, therefore there is a need to develop an alternative, more efficient method. There is an interest in development of micropropagation technology for the species, as it allows to obtain a lot of offsprings in a relatively short time. The aim of the present work was to estimate an influence of explants type and position on regeneration of Mandevilla sanderi in tissue culture. Four different types of explants (leafy shoot tips, decapitated leafy shoot tips, defoliated shoot tips, decapitated and defoliated shoot tips) were used in the experiment, which were placed on the media vertically, while defoliated shoot tips were placed horizontally or vertically upside down. The explants were cultivated on a Murashige and Skoog (MS) medium supplemented with 1 mg·dm–3 benzyladenine (BA) and 0.5 mg·dm–3 indole-3-butyric acid (IBA). It was noted that both explants orientation and positioning, influenced the multiplication rate. Defoliated shoot tips placed horizontally were characterized by higher multiplication rate (6.8) in comparison to upside down vertical positioning (3.2). It was also observed that removal of shoot apex improved axillary branching, while defoliation of shoots placed in a normal position reduced multiplication rate.

    Opis:
    Initiation of tissue culture of many plant species is a very difficult stage due to appearance of many contaminations. The other problem might be a choice of media for regeneration. Initiation of grass species tissue cultures are thought to be very difficult. Therefore, a research was undertaken to evaluate the use of nano-silver particles for plant material disinfection and to estimate a medium Pennisetum alopecuroides. The plant material were buds and nodal explants that were disinfected in 2% NaOCl for 30 min or 0.1% HgCl2 for 1 min. Half of the explants disinfected with NaOCl were soaked in 50, 100 or 250 mg·dm–3 Ag NPs for 1 hour. Explants not soaked in nano-silver were placed on media with Ag NPs at concentrations of 4, 8 or 16 mg·dm–3. An influence of growth regulators on Pennisetum alopecuroides was evaluated in vitro. Regenerated shoots were placed on MS media with: 3 mg·dm–3 BA + 0.3 mg·dm–3 IBA, 3 mg·dm–3 KIN + + 0.3 mg·dm–3 IAA, 1 mg·dm–3 BA + 0.1 mg·dm–3 IBA. It was observed that the use of nano-silver particles lowered the level of contamination. The best results were obtained when Ag NPs was used at concentration of 100–250 mg·dm–3 alone or as a supplementation of the media, at concentration of 4 mg·dm–3 for nodes and 16 mg·dm–3 for adventitious buds. The use of nodal explants allowed to obtain less contamination. Regeneration depended on a media content. The most regenerated shoots were obtained on the MS media supplemented with 1 mg·dm–3 BA and 0.1 mg·dm–3 IBA.

    Opis:
    We investigated direct and indirect formation of somatic embryogenesis in Brassica oleracea var. botrytis (cauliflower), a very important vegetable crop worldwide. Direct somatic embryogenesis, which is rather rare, was achieved in culture of 2-week-old hypocotyl explants of Brassica oleracea var. botrytis on MS medium supplemented with 1.0 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.5; 1.0; and 1.5 mg/l kinetin. Initial induction of embryogenic callus was achieved on MS supplemented with very low concentrations of 2,4-D (0.05 mg/l and 0.1 mg/l). Indirect somatic embryogenesis from leaf sections was obtained on MS supplemented with 0.05 or 0.1 mg/l 2,4-D. We examined various stages of somatic embryos (globular, heart, torpedo, cotyledonary). More embryos per explant were produced through the indirect pathway (23–25) than through the direct pathway (14–19). The number of embryos produced was high. There is a potential for recurrent, repeated or secondary somatic embryogenesis, possibly an unlimited source for mass propagation and ideal for synthetic seed production in this species. Plant regeneration was achieved on half-strength MS medium without any hormones.
