    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:
    A vanishing species in Poland - Plantago maritima L. was regenerated in vitro from tips of shoots (obtained in vitro) and from different explants of 4-week-old seedlings: seedling tips, hypocotyls, cotyledons, roots. Murashige and Skoog basal medium, supplemented with 0.6 pM indole-3-acetic acid in combination with cytokinins 6-benzyladenine, zeatin or kinetin, was used. The plants obtained in the result of micropropagation were normal in appearence. It was proved that Plantago maritima species was amenable to propagation from different kinds of explants. The method may be of significance for protection of sea plantain.

    Opis:
    The experiments were carried out on Lotus corniculatus (L.) seedling root explants of the cultivar varieties Skrzeszowicka, Caroll A10 and strain 175. Callus formation and shoot regeneration were the major explant response depended mainly on of the studied genotype and used plant growth regulators (PGRs). Primary cortex of proximal and distal end of explant was the most active tissue for callus proliferation. For shoot primordia differentiation deeper zones of cortex took a part. The process of meristematic centre initiation was not uniform and various level of shoot differentiation events were observed not earlier than 3 weeks of culture. Usually, the shoot primordia regeneration began on proximal rather than distal end of the explant. BAP rather than urea derivatives stimulated shoot proliferation in extended cultures. Increasing of BAP and TDZ concentrations brought about the explant polarity and expansion of the meristematic zones. The explant position in root did not have significant influence on the number of regenerated shoots. The cultures only had better bud formation by TDZ when compared to BAP. BAP stimulated bud formation and development of the shoots from them. Short term of TDZ treatment of explants stimulated meristem formation which developed into buds and shoots. CPPU stimulated callus proliferation and bud formation when explants pretreatment was prolonged from 12 to 36 hrs.

    Opis:
    The paper presents investigation on influence of root shortening on growth of 2−years−old Norway spruce seedlings after their development in the nursery. Measurements of basic morphological features reveal that strong length reduction increases regeneration of spruce root system. Together with that, slight decrease in height and diameter increment of the main shoot can be observed. Shortening of spruce roots improves significantly the balance between above− and belowground parts of the seedlings as well.

    Opis:
    The goal of this paper was to prove the possibility, and determine the most important hazards of beech planting stock production under the climatic conditions of north−eastern Poland. Considered were time of sowing, soil coverings and mulch type in four operational nurseries of the State Forests over the period of four years. The use of simple nursery technological solutions in bare−root forest nurseries is sufficient for the production of quality beech planting stock, also outside the natural distribution limits of the species. The most crucial natural factors for the production of beech seedlings proved to be: spring frost, damage to seed and seedling by maggots and birds. It was estimated that before the early frost, all seedlings had produced the top bud. The autumn sowing with use of sawdust covering was found to be the most effec− tive technological solution in the sense of planting stock productivity. The spring sowings were less effi− cient because of the necessity to use properly stratified seed, a condition hardly met in the poorly equipped bare−root nurseries. The largest 1/0 seedlings (dry weight per seedling) were those originated after the autumn sowing. The smallest seedlings were grown in plots with coniferous sawdust coverings. Another finding of the study was that the use of above ground covers, allowing 40% daylight intensity had reduced the final dimensions of the one−year old beeches.
