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:
We used germination tests to assess the frequency of polyembryony in 9 asparagus cultivars with a high propensity to produce double embryos with different ploidy levels: Alpha, Andreas, Boonlim, Cipres, Eposs, Helios, Limbras, Ravel and Sartaguda. Twin embryos inside a single seed were found in 3 cultivars: Eposs 2n, Ravel 2n and Sartaguda 2n, at 0.60% frequency (15 seeds with twin embryos out of 2500 seeds). Of 30 obtained seedlings, 14 were separated diploid-diploid twins, 6 were conjoined diploid pairs, 8 were separated diploid-haploid and 2 were diploid-haploid pairs conjoined in the hypocotyl region. Some embryos showed unilateral dominance of one embryo (size and shape). The haploid status of the smallest embryo was confirmed by chromosome number (n=x=10) and flow cytometry (nuclear C DNA amount 1.95 pg). The haploid obtained in this manner possessed enough vegetative vigor to undergo chromosome doubling.

Opis:
In vivo and in vitro self-pollination of whole pistils of some clones of Salix viminalis enabled to obtain mature seeds containing cotyledonary embryos which after the transfer to MS medium developed into wholly formed seedlings. Pollination in vitro of placentae led to abundant pollen germination and formation of tubes which occasionally they were entering the ovules through micropyle. Fertilized ovules normally developed into germinable seeds. Distant pollination of stigmas in vivo and in vitro with pollen grains of Populus tremula, P.tomentosa, P. lasiocarpa showed the ability of pollen to germinate and to form tubes several hours after pollination. Some tubes penetrated the styles but did not enter into the placenta. When placentae were directly pollinated than pollen germinated abundantly and occasionally pollen tubes were found entering the micropyle. Embryological analysis of those ovules performed 3-5 days after pollination demonstrated the presence of globular embryos with several endosperm nuclei. The technique of in vitro placental pollination works well for Salix viminalis and it could probably be applied to other Salix species.

One-year old shoots of Rhododendron ‘Cunningham’s White’ and R. ‘Nova Zembla’ from which cuttings were obtained. The cuttings consisted of epidermis, periderm, cortex, sclerenchyma, phloem, cambium, xylem and pith. Adventitious roots of cuttings of that taxa were developed throughout basal burls or directly in cambium region.

Opis:
The pollen–stigma interaction plays an important role in reproductive process and has been continuously studied in many interspecific and intergeneric crossing experiments. The aim of this study was to investigate stigma receptivity (SR) of willow in order to determine the most suitable period for its pollination with poplar pollen and improve the effectiveness of Salix × Populus crosses. Tissue samples were examined histologically using light, epifluorescent, scanning, and transmission electron microscopy. Willow SR was determined by stigma morphological traits, test of pollen germination rate, Peroxtesmo test of peroxidase and esterase activity on stigma surface as well as papilla ultrastructure at anthesis. We have ascertained that the SR duration in willow is short, lasting from 1 to 2 DA. The poplar pollen germination rate on willow stigmas on 1 DA ranged from 26.3 to 11.2%.
