What processes in the system of the Ukrainian national language refl ect the word forms of the imperative which we fi nd in works by the outstanding Ukrainian poet B. Antonych? Thus some peculiarities of the individual speech of the poet, refl ecting peculiar features of his native Lemkiv dialect, are the reason to study the relationship between the morphological structure of word forms of the imperative mood and the type of their stress. The study of system interdependences and relations, existing at different structural levels of the Ukrainian language system, will give a possibility to identify a lot of characteristics of the Ukrainian verb in modern Ukrainian lexicography.

The text presents two case studies from the area of Polish middle voice morpho-syntax. One case concerns anticausatives formed with the particle się and their simpler counterparts based on identical roots. The other – "clear" alternating frame verbs, their prefixed correspondents and middle formations based on the same roots. The first case strikes us as problematic for both modern approaches to morpho-syntax in generative grammar – the lexicalist approach and the root based construction approach. It turns out to be problematic for the first model only, if certain proposals (in particular Alexiadou and Doron 2012) concerning non-active morpho-syntax are discarded. The second case shows, however, that certain data cannot be explained within the root based grammar, while the lexicalist mechanisms account for them naturally. Polish morpho-syntax calls for introducing clear demarcation lines between the data that can be rendered by syntactic mechanisms and such which require lexical analyses and "productivity" of the data cannot provide such a boundary. They need to be drawn on an empirical basis.

The processes of growth and development as well as the yield quality of crops depend on the abundance of soil nutrients and the ability of the plants to uptake nutrients. Nutrients can be taken up more efficiently after application of a biostimulant. The effect of biostimulants depends on the content of their active substance as well as the dose, timing and frequency of their application. In 2009-2011, a controlled field experiment was conducted in the Kuyavian-Pomeranian Province (53°13′N; 17°51′E). The objective was to analyse the effect of the timing and doses of foliar application of the biostimulants: Kelpak SL (seaweed extract containing phytohormones) and Asahi SL (a mixture of phenolic compounds) on the content of macroelements: Mg, P, Ca, N, Na and K in the storage roots of carrot directly after harvest and after storage (for 6 months in chambers with controlled conditions: temp. +1°C, Rh 95%). Kelpak SL was applied once in a dose of 3 or 2 dm3 ha-1, twice in doses of 3+2 dm3 ha-1 or 2+2 dm3 ha-1 at intervals of two or four weeks, as well as three times in doses 3+2+2 dm3 ha-1 or 2+2+2 dm3 ha-1, every two weeks. Asahi SL was applied twice in doses 0.5+0.5 dm3 ha-1,at a two-week interval. The first application of biostimulants was always performed at the 4-leaf stage. The study showed that the biostimulants Kelpak SL and Asahi SL, irrespective of the dose and frequency of application, increased the N concentration in the carrot roots. An increase in the Mg, P, Na and K concentrations was observed after a single application of Kelpak SL in a dose of 2 dm3 ha-1, and in the Ca concentration after a dose of 3 dm3 ha-1. Asahi SL did not affect the Mg, P, Ca and Na concentrations but increased the K content in the roots. After storage, the content of Mg, Na and K decreased, whereas the concentration of P, Ca and N did not change. Directly after harvest and after storage, positive correlation between N and K and between N and Na, as well as between Na and K was indicated.

The suitability of Eucalyptus grandis bark and root for the pulp and paper industry was investigated. The bark of E. grandis was cooked using sodium borohydride (NaBH4) in the kraft process, while the root of E. grandis was cooked using the soda-anthraquinone (AQ) process. Four different charges (0.0, 0.3, 0.5, 0.7%) of NaBH4 and AQ used as catalysts were added to the cooking liquor used in the processes. The chemical, mechanical and optical properties of the produced pulps were investigated and characterized. The yields, viscosity values, kappa numbers, as well as the brightness, tensile, burst and tear indices of the pulps were determined. The yield (RP: 39.1%, BP: 36.8%), viscosity value (RP: 897 cm3/g, BP: 650 cm3/g) and the kappa numbers (RP: 90, BP: 50) of the pulps produced from the root (RP) were higher than those of the pulps produced from bark (BP). The catalysts generally affected all the pulp properties, improving the properties of BP and RP. It was concluded that E. grandis bark and root can be suitable for the pulp and paper industry.

The aim of our work was to investigate the antioxidant activity of Rheum palmatum extracts. Antiradical activity against DPPH and ABTS radicals, reducing power FRAP and total phenolic contents, were investigated in one-, two- and three-year-old roots of rhubarb fertilized with nitrogen at the rates of 50, 100 and 200 kg N/ha. It was proved that nitrogen dose as well as the age of plantation did significantly influence antioxidant activity and total phenolic of root extracts. The highest values were determined in one-year-old plants, antioxidant activity ranged the level of 112–203 µM Trolox/g and total phenolic compounds average content was 22 mg GAE/g FW. Two-year-old roots were characterized by 3–11%, and three-year-old ones by 15–23% lower antioxidant activity and phenolic compounds content. When nitrogen dose increased, polyphenols content, DPPH and FRAP values increased as well, although, ABTS showed a different tendency.

Celem badań była ocena aktywności antyoksydacyjnej oraz zawartości polifenoli w ekstraktach z korzeni rzewienia dłoniastego. Aktywność antyoksydacyjna mierzona testami ABTS, DPPH i FRAP i zawartość polifenoli ogółem, była oceniana w roślinach jedno-, dwu-, i trzyletnich nawożonych azotem w dawce 50, 100, 200 kg N/ha. Stwierdzono, że zarówno dawka azotu jak i wiek rośliny miały istotny wpływ na aktywność antyoksydacyjną i poziom polifenoli w surowcu. Największą aktywność antyoksydacyjną 112–203 µM Trolox/g stwierdzono u roślin jednorocznych. Również u tych roślin odnotowano największą zawartość polifenoli (22 mg GAE/g św. m.). U roślin dwuletnich wartości te były o mniejsze o 3 i 11%, zaś u trzyletnich o 15 i 23%. Wraz ze wzrostem dawki azotu wzrastała aktywność antyoksydacyjna (testy DPPH i FRAP) i zawartość polifenoli.

A concentration of two phenylethanoids in the roots of two species: Rhodiola kirilowii and rosea were compared, aqueous and hydroalcoholic extracts from those plants were also analyzed. In order to determine the content of p-tyrosol and salidroside, the ultra performance liquid chromatography connected with a tandem mass spectrometry (UPLC-ESI MS/MS, Waters) was used. The obtained results shown that content of measured phenylethanoids depends on Rhodiola species. Roots of R. kirilowii contain more p-tyrosol, while R. rosea roots are reacher in salidroside. Our results indicate that the application of UPLC MS/MS method allows to determine the phenylethanoids content in tested samples with satisfactory precision.

Przedmiotem badań było zwalidowanie metody analitycznej oznaczenia zawartości fenyloetanoidów. Do detekcji p-tyrozolu i salidrozydu w analizowanych dwóch gatunkach różeńca wykorzystano wysokosprawny chromatograf cieczowy sprzężony z tandemowym spektrometrem mas (UPLC-MS/MS). Analizie poddano Rhodiola kirilowii oraz Rhodiola rosea uzyskane z hodowli gruntowej w 2009 r. w Instytucie Włókien Naturalnych i Roślin Zielarskich w Poznaniu. Dodatkowo z surowca przygotowano dwa wyciągi suche: wyciąg wodny i wyciąg wodnoalkoholowy (50% wyciąg etanolowy). Zawartość poszczególnych składników różni się w zależności od analizowanej matrycy.
