    Opis:
    The aim of the work was to evaluate the influence of cytokinins on in vitro propagated dahlia and their consequent effect on acclimatization. Plant material consisted of shoot tips and nodes. Among the three cytokinins, benzyladenine, kinetin and 2-isopentenyl-adenine, only BA effectively stimulated the shoot multiplication from axiliary buds. The highest multiplication rate was obtained from nodes in the presence of 0.25– 0.5 mg·dm–3 BA. Higher concentrations shortened the internodes and decreased the leaf blades and growth of callus. 1 mg·dm–3 of KIN and 2iP positively influenced the shoot growth and size of leaves. Gibberellic acid (GA3) used with BA increased the number of auxillary shoots. The best quality shoots and the highest multiplication rate were obtained when 2 mg·dm–3 BA was used with 5 mg·dm–3 GA3. Cytokinins affected the rooting and acclimatization ex vitro. Dahlia shoots multiplicated in the presence of 1 mg·dm–3 KIN or 2iP rooted faster in the soil and 100% survived in field, while those from 1 mg·dm–3 BA media rooted slowly, had shorter shoots and only 60% of them survived. Plants bloomed after 11–12 weeks in the field. Dahlia plants that had been multiplicated in the presence of KIN had larger diameter and fresh weight in the field. BA and 2iP positively influenced the flower diameter, length of flower stalk and a number of the first-order shoots.

    Opis:
    Garden perennials are a source of floristry material produced in field or under covers. A perennial producing long, leafy shoots, which in flower arrangements might successfully substitute fern or palm leaves, is Polygonatum multiflorum. The variety characterizing with decorative white margined leaves is ‘Variegatum’. To improve their quality, the growth stimulator Actisil Hydro Plus, which contains 0.6% of active silicon in a form of orthosilicic acid was applied. The aim of the conducted experiment was to estimate the influence of silicon and a place of cultivation (tunnel and open field) on post-harvest quality determined with morphological features, vase life longevity and mechanical properties of Polygonatum multiflorum (L.) All. ‘Variegatum’ stems. The plants were sprayed with water solutions of Actisil in concentrations: 0.2%, 0.3%, and 0.4%, six times during the growing season in weekly intervals, starting from the first decade of May, always in the morning. It was stated that cultivation of Polygonatum in the unheated foil tunnel increases quality of shoots for cut greenery, determined with morphological features and post-harvest longevity. Cultivation of Polygonatum in a foil tunnel and spraying plants with Actisil in concentrations of 0.3 or 0.4% is advantageous due to possibility to increase a number of shoots from 20% to over 31%, their length from 9% to 11% and fresh weight from 52% to 71%, in comparison to control plants. It is advised to treat plants cultivated in a tunnel, with Actisil in concentration of 0.4% as it improved shoots quality evaluated with their diameter and lower leaves blade area. Spraying plants with Actisil in concentrations of 0.2–0.4% in the tunnel and 0.2% in field prolongs post-harvest shoots longevity by 3–4 days. Plants cultivated in the tunnel characterize with higher strength of shoots determined with higher maximum force causing permanent damage and lower stem deflection than plants cultivated in field. Plants grown in a tunnel and sprayed with Actisil in concentrations of 0.4% characterized with the strongest shoots after 14 days of storage, however a similar effect was observed with the concentration of 0.3% and in case of plants cultivated in field and sprayed with 0.4% of Actisil.

    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.
