    Opis:
    Somatic embryogenesis was studied in four spruce species (Picea abies, P. omorika, P. pungens 'Glauca' and P. brewenana) to determine if this method can be used for in vitro propagation of coniferous trees. The highest frequency of initiation of embryogenic tissue was obtained when mature zygotic embryos were used as explants. It ranged then from 10.8% (P. brewenana) to 23.75% (P. omorika and P. pungens 'Glauca'). The frequency of embryogenic tissue initiation was strongly affected by medium composition, i.e. addition of appropriate auxins (2,4-D, NAA, Picloram) and sucrose concentration (10-20 g-1"1). A lower frequency was obtained in Picea omorika (10%) when megagametophytes (endosperms with immature zygotic embryos) were used as explants. No emryogenic tissue was produced from hypocotyls, cotyledons and needles. A satisfactory frequency was achieved with the use of somatic embryos of Picea abies (30%). The proliferation of embryogenic cell lines of spruces was affected by medium type. The experiments resulted in production of somatic plantlets of P. abies and P. omorika. This enables the application of this method of spruce micropropagation for genetic and breeding research or for nursery production.

    Opis:
    Somatic seeds of Plantago asiatica L. were produced for the first time. Shoot-tips isolated from in vitro obtained 4-week shoots were encapsulated using sodium alginate and calcium chloride. Capsules with or without sucrose and with and without cytokinin - indole-3-butyric acid (IBA) were used. Sucrose presence in capsules very distinctly influences somatic seeds of Plantago asiatica germination and their conversion into plants. However, addition of IBA to capsules has not clear influence on the ability of plant regrowth. Plantlets transplanted to soil grew to phenotypically normal plants.

    Opis:
    Two-dimensional gel electrophoresis was used to compare protein expression profiles between various stages of Gentiana kurroo Royle somatic embryos. Seven distinct stages (I–VII) were pointed out and measured from long-term embryogenic cell suspension. Isoelectric focusing was done in the pH intervals 3–10, and the second dimension was carried out with 13% SDS-polyacrylamide gel electrophoresis. Dependent on the stage from about 400 (stage IV) to more than 700 (stage II) protein spots were totally detected. The molecular weight of abundant proteins range from 12 to 70 kDa, however, majority of proteins were located between 20–49 kDa spots on the gels. The highest difference in the number of spots appeared in the case of globular embryo (stage I) and elongated cotyledonary stage (stage VII) with differences being about 130 spots. The relevance of embryogenic cell suspension choice for proteomic analysis as well as expediency of the increasing number of particular embryo stages is discussed.

    Opis:
    The effects of TDZ and paclobutrazol on the primary regeneration on tulip flower stalk explants of six cultivars and subsequent shoot multiplication were examined. Explants, flower stalk slices, were excised from cooled and subsequently forced bulbs. The explants were incubated for two months in darkness on medium containing NAA and cytokinins, 2iP and BAP, as control, or TDZ (0.5-4 mg l-1) and paclobutrazol (0.05-0.4 mg l-1). Then, the regenerating explants were subcultured on medium with TDZ and NAA applied at low concentrations. Different regeneration capabilities were found depending on cultivar and growth regulators. The percentage of explants forming leaf-like structures ranged, on the control medium, from 80% in 'Blue Parrot' and 'Prominence' to below 30% in 'Apeldoorn' and 'Mirjoran'. TDZ, applied at optimum for each cultivar concentration, greatly increased the regeneration potential up to 70-100%. Paclobutrazol, added to the TDZ-containing medium, significantly enhanced the response of explants, resulting in high numbers of leaf-like structures formed per explant (13.7-22.8). The structures developed gradually into characteristic forms: the growing up cotyledonary leaf, the probable root primordium formed at its base, the growing downwards stolon and the shoot meristem developed finely on its tip. It is suggested that such primary regeneration may have a nature of somatic embryogenesis. Then, the adventitious shoots developed and formed clusters, which were divided into 2-3 smaller ones every two months. The growth regulators, used at initial stage, markedly influenced subsequent shoot multiplication. Thus, the most intensive shoot formation was noted with TDZ at concentrations of 0.5-2 mg l-1 and paclobutrazol of 0.05-0.1 mg l-1.
