Opis:
This paper is a short review of historical development of the tissue culture method in Poland. Similarly to the rest of the world, in vitro technology in Poland has progressed in many directions simultaneously. Its main fields are closely interconnected by natural sequences of biological processes and integrade one into another. The best results, driven by the prospects of practical applications, have been achieved within the areas of meristem culture and micropropagation of valuable genotypes, somaclonal variation, production of haploids and DH plants, somatic embryogenesis, in vitro culture of embryos and ovules, improvement of plant disease resistance, somatic hybridization and transformation of plants. Due to the fact that in vitro domain is a very broad science the authors are aware that this review might not fully cover all the scientists working with tissue culture and their achievements.

Opis:
The Far East medicinal plant - Plantago camtschatica was propagated in vitro from tips of shoots (obtained in vitro) and from different explants of 4-week-old seedlings: seedling tips, hypocotyls, cotyledons, roots, first leaves. To our knowledge there is no information in literature about in vitro culture of this plantain. MS basal medium, supplemented with 0.6 pM IAA in combination with various cytokinins (BA, KIN, ZEA), was used. After 6 weeks of culture, micropropagation rate (MR) - mean number of buds and shoots per explant - was calculated. Our study proved that P. camtschatica species was amenable to propagation in vitro from different kinds of explants. However, multiplication by adventitious shoot regeneration from hypocotyl explants was found to be the most suitable method for the propagation of this plant. Adventitious shoots could root without stimulation what allows to omit the stage of rooting. The plants obtained as a result of micropropagation were not phenotypically changed.

Opis:
Various explants from 30-day-old seedlings of Centaurium erythraea Rafn were evaluated for their morphogenetic capacity under in vitro culture conditions. Shoot formation from shoot tip explants was achieved mainly through adventitious bud differentiation. The highest number of shoots (up to 43.3 ± 2.2 from a single shoot tip) was obtained on Murashige and Skoog medium (MS) supplemented with indole-3-acetic acid (IAA) (0.57 μM) and 6-benzylaminopurine (BAP) (4.4 μM). Adventitious shoot regeneration was also achieved through organogenesis from calluses obtained from hypocotyls, cotyledons, roots and leaves on MS medium containing IAA (2.85 μM) and BAP (0.88 μM). Significant differences were noted between explant types in their effects on shoot regeneration. In the primary culture, the best response was obtained either from calluses derived from roots or leaves (44.4 ± 4.5 and 40.2 ± 6.0 shoots per callus, respectively). The number of subcultures of inoculated calluses affected both the multiplication rate (the number of shoots/explant) and shoot morphology (the frequency of shoot hyperhydricity). Shoots rooted with the frequency of 94-100% after culture on MS medium without growth regulators. Plantlets were successfully acclimatized (97%) under high relative humidity and then moved to the greenhouse.

Opis:
Experiments had been carried out on gametophytes and very young fronds of sporophytes with application of Murashige and Skoog (1962) medium. The paper described the results of 15 years in vitro experiments on 16 species of tree ferns belonging to various genera: Blechnum, Cibotium, Cyathea and Dicksonia. Genus Cyathea was represented by: C. australis (R.Br.) Domin., C. capensis (L.f.) Sm., C. cooperi (F.Muell.) Domin, C. brownii Domin, C. dealbata (G.Forest) Sw., C. dregei Kunze, C. leichhardtiana (F.Muell.) Copel., C. robertsiana (F.Muell.) Domin., C. schanschin Mart., C. smithii Hook.f. and Cyathea sp. In case of genus Dicksonia only two species were introduced into our experiments: D. fibrosa Colenso and D. sellowiana Hook.. Taxa Blechnum was presented by B. brasiliense Desv. and Cibotium by C. glaucum (Sm.) Hook. and Arn. and C. schiedei Schltdl. and Cham.. The studied species presented various responses on culture conditions depending on the level of stage of development. Time required for spores germination differed between species and took from only a few to 16 weeks. Prothalium formations showed various types of growth presented by marginal meristems. For all investigated species long term gametophyte in vitro cultures was established. Mature gametophyte possessed functional antheridia and archegonia. Spontaneous fertilization helped to establish the culture of young sporophytes. For all species the ex vitro culture in greenhouse collection was established. Manipulation of sucrose content in the medium stimulated the multiplication of gametophytes, but its lack induced formation of gemmae. Apospory was observed when culture of very young fronds was extended for 6 months and new generation of gametophytes was developed. Finally, sporophytes of 12 species were obtained and they have been growing in our greenhouse.

Opis:
The results of PCR examination indicated that during two years of tissue culture at standard conditions, on the medium with BAP 1 mg l-1 and continuous temperature of 20oC, phytoplasma could be detected in diseased plants of rose cv Sacha and Jazz. In the second year of micropropagation phytoplasma detection rate in tissues of infected roses increased and was relatively higher than in the first one. To test whether phytoplasmas are sensitive to temperature and light intensity, phytoplasma-affected micropropagated rose plants were grown on medium with BAP 1.0 or 0.5 mg l-1 and at the temperature of 4, 15, 20 or 25oC in darkness or in the light. PCR analysis indicated that phytoplasma detection was not effected by these conditions during 4 weeks of culturing. However, phytoplasma was not detectable in rose plants after 8 weeks culturing on the same medium without transplanting. Micropropagated rose shoots maintained on medium with Gentamycin or Baytril at the concentration of 25.0 or 50.0 mg l-1 had reduced growth and were chlorotic. However, no direct effect of applied antibiotics on phytoplasma detection was evidenced.

Opis:
The concentrations of carnosic acid, carnosol and rosmarinic acid in different materials from differentiated (multiple shoot cultures and regenerated plants) and undifferentiated (callus and cell suspension) in vitro cultures of Salvia officinalis were determined by HPLC. The results suggested that diterpenoid (carnosic acid and carnosol) production is closely related to shoot differentiation. The highest diterpenoid yield (11.4 mg g-1 for carnosic acid and 1.1 mg g-1 for carnosol) was achieved in shoots of 10-week-old micropropagated plants. The levels were comparable to those found in shoots of naturally growing plants. Undifferentiated callus and cell suspension cultures produced only very low amounts of carnosol (ca. 0.05 mg g-1 of dry weight). In contrast, content of rosmarinic acid in callus and suspension cultures as well as shoots growing in vitro and in vivo was similar and ranged between 11.2 and 18.6 mg g-1 of dry weight.

Shoot-tip multiplication of the medicinal species - Plantago asiatica was carried on MS medium with IAA and BAP or kinetin. Best results in micropropagation were achieved by adding 0.1 mg/dm3 IAA and 1 mg/dm3 BAP. After 6 weeks shoots were transferred to MS medium for rooting. The resulting plantlets were transferred after 8 weeks into pots and after a period of adaptation into the ground (field culture). The species Plantago asiatica was propagated in vitro by shoot-tip multiplication for the first time.

Opis:
Experiments on somatic embryogenesis in selected spruce, fir and larch species were performed to determine if this method of micropropagation enables production of quality seedlings for forest nurseries. High frequencies of embryogenic callus in spruce (23-31%) and fir (29%) were achieved when mature zygotic embryos were used as explants, while in larches (36%) only when megagametophytes (endosperms with immature embryos) were used. The possibility of somatic embryogenesis initiation also from somatic embryos (resulting in secondary and third generation of embryogenic callus) indicate high efficiency of this method of micropropagation. The best results at all stages of somatic embryogenesis (good proliferation of embryogenic callus, high rate of embryo regeneration and their survival) were obtained for Norway spruce, European larch and some hybrid larches.

The presence of acteoside substantially supports a placement of the family Byblidaceae in order Scrophulariales and subclass Asteridae. Moreover, the genera containing acteoside are listed; almost all of them appear to belong to the order Scrophulariales.

Opis:
In order to estimate the best germination conditions of Encyclia aff. oncidioides seeds, five different media (Fast, Knudson C modified by Vajrabhaya, Murashige and Skoog, PB2 and modified Vacin and Went) with different concentrations of plant growth regulators such as benzyladenine (BA), naphthaleneacetic acid (NAA) and gibberellic acid (GA3) were tested. No beneficial effect was observed when BA and NAA were applied to the germination medium and GA3 inhibited germination. The effect of light, activated charcoal, coconut water and casein hydrolysate on seed germination was also studied. The growth rate of seedlings on three different media supplemented with activated charcoal and plant growth regulators was checked. The applied plant growth regulators had no beneficial effect on the further growth of seedlings. Fast and PB2 media with 0.2% activated charcoal proved to be the best for E. aff. oncidioides seed germination, seedling development and plantlet propagation.

Opis:
The aim of the experiment was to determine suitable substrate type and optimal plant size for transfer of plantlets from in vitro to ex vitro under experimental outdoor conditions. Tests focused on the effect of substrate type (muddy and sandy) and starting size of plantlets gained through in vitro seed germination (0-3, 3.1-5,5.1-6, 6.1-10 cm) on plant growth. Three parameters (fresh weight, length, and the number of leaves) were compared to evaluate growth. Basic water parameters in experimental water tanks were regularly measured (pH, temperature, electrical conductivity, shadow intensity) and controlled to reach similar conditions to those in the natural habitat of this species. Overwintering was studied in a cellar with newly defined size categories (<6, 6.1-8, 8.1-10, 10.1-12, 12.1-15 cm). Both substrate type and starting size of plantlets significantly impacted growth. Plantlets grew better in the muddy substrate while a 100% success rate of rooting was gained with a starting size of 6.1-10 cm in both substrates. The biggest increase in fresh weight was observed with a starting size of 3.1-5 cm and 5.1-6 cm in both substrates. The greatest increase in fresh weight was observed in plants with a starting size of 3.1-5 cm in the muddy substrate (more than 95% increase). The best overwintering results were gained in the 6.1-8 cm size category.

The aim of the studies was to establish in vitro conditions for the culture of pea and lupin embryos as the first step in the development of an in vitro assisted single seed descent technique for the attainment of homozygous populations. Materials for the study included of pea, and narrow-leafed and yellow lupin cultivars. Embryos dissected from mature but still-green seeds were cultured in vitro on two modified MS media and under three temperature regimes. Shoot and root lengths of regenerated plants were measured after 7, 14 and 21 days of culture. For pea plants full-strength MS medium with 4 g l−1 agar and temperature 22/ 20°C (day/night) appeared to be the most conducive to shoot and root development, whereas for lupin plants lower temperatures were more propitious: 12°C in the dark for narrow-leafed lupin and 16/ 12°C (day/night) for yellow lupin. Almost all the cultured embryos developed into plants, but not all the regenerated plants survived acclimation to ex vitro conditions.

Opis:
Shoot tips from in vitro plants of four rose species were cryopreserved by the droplet vitrification method. Optimized conditions involved exposure to loading solution for 20 min, then treatment with plant vitrification solution (PVS2) for 20 min (Rosa agrestis, R. canina and R. dumalis) or 30 min (R. rubiginosa) followed by freezing in liquid nitrogen. Survival rate ranged from 78.3 to 95.1%, depending on the species. Regrowth rate of shoot tips was 50.5% for R. agrestis, 63.2% for R. rubiginosa, 71.4% for R. dumalis and 78% for R. canina. The preculture of donor plants in a medium with 0.25 цЫ sucrose facilitated the isolation of shoot tips and increased regrowth rate after cryopreservation. Plant regeneration was carried out in Murashige and Skoog medium with 1 цЫ 6-benzylaminopurine, 1.5 цЫ gibberellic acid and 0.087 M sucrose. Plants regenerated from cryopreserved shoot tips did not display morphological alterations in comparison with non-cryopreserved shoot tip - derived plants.

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.

Opis:
July and September. The most efficient regeneration and axillary multiplication were achieved on the medium supplemented with meta-topolin. The application of BAP caused a lower regeneration potency of explants and resulted in a decrease of shoot quality with every subculture. Four of the six cultivars showed growth inhibition after three months of growth on BAP-medium. The highest multiplication rate (2.7-4.7 depending on genotype) and the high quality of shoots were noted on the medium supplemented with mT (0.5-1.0 mg l-1). It is also very important to note that mT had stimulating effect on organogenesis in P. × hederaefolium and P. × hortorum cultivars over the long term. Moreover, meta-topolin had no after-effect on the growth and inhibition of rooting. Only one cultivar ("Sofie Cascade") rooted better on control medium without auxin. In case of the other cultivars, IBA added in concentrations of 0.01-0.1 mg l-1 had a stimulating effect on root production. The higher level of auxin inhibited root formation, stimulated senescence of shoots and had a negative after-effect on acclimatization in greenhouse conditions.
