This study aimed at evaluating the physiological activity of common bean grown under the conditions of stress being induced by salinity and nitrogen deficiency and its lack in substrate. Three series of two-factorial hydroponic experiment with the common bean (Phaseolus vulgaris L.) cultivar Basta were carried out from May to July in 2013–2014. The first experimental factor was three levels of nitrogen content in a Hoagland hydroponic medium (level 1 – a complete medium, level 2 – without 50% N, level 3 – without 100% N). The second experimental factor was three levels of medium salinity (level 1 – no NaCl addition, level 2 – 30 mM NaCl addition, level 3 – 50 mM NaCl addition). Nitrogen deficiency in a Hoagland hydroponic medium, together with increased salinity level, significantly affected the changes in the physiological parameters of the common bean cultivar Basta being tested, i.e. assimilation pigment concentration (chlorophyll-a, chlorophyll-b and chlorophyll-a+b and carotenoids), assimilation and transpiration intensities, and RWC (relative water content). The 50% nitrogen deficiency in medium induced a significant increase in the concentration of all assimilation pigments in common bean leaves and was by far the highest among the experimental variants being tested. A significant decrease in the content of assimilation pigments was observed in the hydroponic mediums without nitrogen and salined with 30 and 50 mM sodium chloride. The interaction of these two experimental factors being analysed, i.e. nitrogen deficiency and its lack in a Hoagland hydroponic medium and its salinity, significantly decreased the intensity of assimilation in bean leaves, while a significant increase in transpiration was observed in the variant without nitrogen and with 50 mM NaCl. The experimental variants being tested had a significant effect on the changes in leaf water balance of the common bean cultivar being tested. Salinity, in interaction with nitrogen deficiency in medium, decreased relative water content (RWC) in leaves, irrespective of their level.

Vegetables are considered to be plants with high water requirements. A greater susceptibility to water deficit occurs in the periods of intensive growth and yield formation. At that time even a slight reduction in water supply can deteriorate yielding, thus those periods are referred to as critical periods in terms of water supply. The aim of this paper has been to analyse the pattern of precipitation deficits for the ground cultivation of cucumber, tomato, beans and peas in the Bydgoszcz region in the thirty-year period 1981-2010. The basic of analysis were results of standard meteorological measurements from the Research Station of the Faculty of Agriculture and Biotechnology ‚Mochełek’, University of Technology and Life Sciences. Values of optimal precipitation for medium soils were calculated according to Klatt. Atmospheric precipitation deficits in subsequent month of selected vegetables cultivation were calculated by diminish between the real and optimal precipitation. The trends of deficiency of precipitation in the examined period were estimated too. Very frequent occurrence of the atmospheric precipitation deficits during the entire cultivation period of selected vegetables, and especially in critical periods was demonstrated. Slight decreasing tendency of precipitation deficits in a vegetation periods was indicated, however in a critical periods in terms of water supply, the trend line remains at a practically constant level. The results obtained indicate the necessity of the irrigation in the cultivation of peas, beans, cucumbers and tomatoes.

W latach 2007-2008 prowadzono badania nad oceną kilku gatunków roślin pod kątem ich wykorzystania w ochronie fasoli przed zmienikiem. Fasolą uprawiano na polu doświadczalnym Instytutu Warzywnictwa w Skierniewicach, posiadającym certyfikat zgodności ze standardami dla uprawy ekologicznej. Wysiewano po 5 rządów fasoli na poletku, którego skrajne rządy obsadzano lub obsiewano rośliną sąsiedzką. Zastosowano następujące gatunki roślin sąsiedzkich: cząber (Satureja hortensis L), majeranek (Origanum majorana L.), szałwia lekarska (Salria officinalis L), aksamitka wzniesiona (Tagetes erecta L), burak ćwikłowy (Beta vulgaris L), cebula (Allium cepa L.J, koper ogrodowy (Apium graveolens L). W obiekcie kontrolnym w miejsce rośliny sąsiedzkiej wysiewano fasolę. Oceniano wysokość i jakość plonu nasion z poletka wyróżniając następujące frakcje: nasiona zdrowe, z plamami, pomarszczone, ospowate, uszkodzone przez strąkowca. Wysokość plonu nasion oraz jego jakość zależały od roku badań. W roku 2007 uzyskano wyższy plon ogólny nasion (średnio 3.67 kg/10 m 2) oraz bardzo wysoki udział nasion ospowatych w strukturze plonu (średnio 31.0%) . W roku 2008 średni plon nasion był wyraźnie niższy(2.77 kg), a, udział nasion ospowatych znikomy (średnio 2.6%). W obu latach badań najmniej nasion ospowatych stwierdzono w obiektach, w których fasola była uprawiana w sąsiedztwie kopru, cebuli i aksamitki.

During 2007-2008 the studies were conducted to examine a protective effect of selected plant species against lygus bugs (Lygus spp.) in organic production of bean. The plants were cultivated on the experimental organic field of Research Institute of Vegetable Crops at Skierniewice. The experiment run in the following scheme: 5 rows of bean, 2 side rows of examined companion species. The examined species were: summer savory (Satureja hortensis L.), marjoram (Origanum majorana L), sage (Salvia officinalis L), big marigold (Tagetes erecta L.), red beet (Beta yulgaris L), onion (Allium cepa L), dill (Apium graveolens L). In the control the side rows were taken by bean plants The seed yield quantity and quality was examined by dividing total yield into following groups : healthy seeds, spotty seeds, wrinkled seeds, pitted seeds, common bean weevil damage seeds. The seed yield depended on the year of research. In 2007 the total seed yield was higher amounting on 3.67 kg per 10 m2 average. The share of pitted seeds in total yield was also high (31.0%). In 2008 the mean seed yield amounted 2.77 kg, and the pitted seeds made only 2.6 % of the total yield. In both years of research the smallest amount of pitted seeds was found when dill, marigold and onion were used as companion plants.

The objective of the paper was to evaluate the impact of microwave stimulation of bean seeds on their germination process. Laboratory tests were carried out in 2012-2014 with the use of certified bean seeds (Phaseolus vulgaris L.) of Igołomska cultivar. Shortly before sowing, bean seeds were radiated with microwaves for 10, 30 and 60 seconds. Microwaves came from a magnetron which operated with 100 W power and produced waves of 2.45 GHz frequency. The germination process was described and parameters, which define the sowing value of bean seeds, were determined. Germination ability, relative germination ability (Maguier's index) and average germination time (Pieper's index). Fresh and then dry mass of plant mass were determined. The obtained results allow the statement that microwaves modify the germination process of bean seeds.

Celem pracy była ocena wpływu stymulacji mikrofalowej nasion fasoli na proces ich kiełkowania. Badania laboratoryjne prowadzono w latach 2012-2014 z wykorzystaniem kwalifikowanych nasion fasoli (Phaseolus vulgaris L.) odmiany Igołomska. Bezpośrednio przed siewem nasiona napromieniowano mikrofalami przez czas 10, 30 i 60 s. Źródłem mikrofal był magnetron działający z mocą 100 W i wytwarzający fale o częstotliwości 2,45 GHz. Zobrazowano przebieg procesu kiełkowania oraz wyznaczono parametry określające wartość siewną nasion fasoli: zdolność kiełkowania, względną szybkość kiełkowania (wskaźnik Maguiera) oraz średni czas kiełkowania (wskaźnik Piepera). Określono świeżą a następnie suchą masę roślin. Uzyskane wyniki pozwalają na stwierdzenie, że mikrofale modyfikują proces kiełkowania nasion fasoli.

Different responses among legume species were observed, but the morphological and physiological differences that confer drought resistance or susceptibility are not well explained. The objective of this study was the determination of variation of morphological characteristics within 7 field bean and 4 field pea cultivars as related to drought tolerance. Also differences in the effect of drought on seed germination and seedling growth in 2 field bean and 2 field pea cultivars of different drought tolerances were investigated. The examined cultivars were characterized by variation of certain morphological characteristics regarded as xeromorphic features associated with the ability of plant to survive under drought. The drought resistant cultivars (field bean Gobo and field pea Solara) in comparison with the sensitive ones (field bean Victor and field pea Bareness) were characterized by more favourable relations between the size of the above—ground parts and the size of root, as well as the frequency and size of stomata. Moreover, in the resistant cultivars there was observed, a smaller influence of simulated drought (ψ=−0.6 MPa) on the increase of dry matter of the above-ground parts and of the roots. Also there was smaller influence on the height of seedlings and on the length of lateral roots. The correlation coefficients between the measured characteristics and the values of the drought susceptibility index (DSI) were in most cases statistically not significant, although, on the whole, they were very high. This may be an indication of a relatively high participation of the measured characteristics in the total variation of the drought tolerance in the cultivars. In cultivars regarded as belonging to the group of sensitive ones, a more disadvantageous effect of simulated drought (ψ=−0.6 MPa) on seed germination was observed, especially in the determination of the promptness index (PI).

Broad bean (Vicia faba L. “Inovec”) seeds were artificially aged by means of storage at 30 %, resp. 25 % water content at 25 °C for 7-days to study the consequences on germination, root length and frequency of chromosomal aberrations. Under these conditions, significant changes in all parameters were observed. An increase of frequency of chromosomal aberrations in ana-telophase cells was confirmed by evaluation of c-metaphase cells. Synergic effect of artificial seed ageing was studied on different harvests of old seeds. Possible principles of this effect on cell level are discussed.
