Opis:: The aim of the study was to determine the effect of high voltage electrical stimulation (330 V, 17 Hz, 120 s) of beef half-carcass and heat treatment on tenderness and water holding capacity of meat. The experimental material was a semimembranosus muscle derived from Polish Holstein-Friesian heifers (n=12). In the experiment, a forced and natural air circulation ovens were used; the raw material was heated at 170ºC to obtain a final temperature from 55 to 80ºC inside the beef. Results showed that electrical stimulation improved tenderness of roasted beef, which was demonstrated in the decrease in the maximum shear force from 39 to 26%. The electrical stimulation had a negative effect on cooking losses during roasting and water content in the final product. It has also been shown that studied quality attributes of beef depends on the type of heat treatment. Beef prepared in forced air circulation oven, were characterized by lower water content and higher values of maximum shear and compression forces than those heated in natural air circulation oven

Opis:: It is shown that the main results of the theory of real interpolation, i.e. the equivalence and reiteration theorems, can be extended from couples to a class of (n+1)-tuples of Banach spaces, which includes (n+1)-tuples of Banach function lattices, Sobolev and Besov spaces. As an application of our results, it is shown that Lions' problem on interpolation of subspaces and Semenov's problem on interpolation of subcouples have positive solutions when all spaces are Banach function lattices or their retracts. In general, these problems have negative solutions.

Opis:: Many plant species can adapt to flooding and hypoxia by forming a root system with an altered architecture: thicker, shorter and shallower adventitious roots, than under aerated conditions. The internal gas transport is often improved by increased root porosity and aerenchyma, which is tissue with large intercellular spaces. The raised root aeration allows better supply of oxygen to plant tissues and diffusion of oxygen into the rhizosphere (Radial Oxygen Loss, ROL). This phenomenon creates narrow, but well aerated zones in the hypoxic soil, where phytotoxins are oxidised and methanotrophic as well as nitrifying bacteria can live. The aim of the study was to determine the change of root archi-tecture, porosity and ROL from roots of Plantago lanceolata plants originating from The Middle Vistula River Gorge. Selected plant species were subjected to transient flooding during 7 days of culti-vation on aerated and stagnant oxygen-deficient hydroponic medium. We observed the formation of shorter hypoxic, adventitious roots (56-69 mm) than control roots (112-196 mm) with high porosity (stagnant 15-21 %, control 8.5-9.4%), and the diameter of aerated zone (halo) increased from control values of 0-1.5 mm to 2-2.5 mm under hypoxic conditions.
Wiele gatunków roślin adoptuje się do powodzi i hipoksji. Mogą formować system korzeniowy o zmienionej architekturze: grubsze, krótsze i płytsze korzenie przybyszowe niż w natlenionych warunkach. Wewnętrzny transport gazów jest często poprawiany przez zwiększoną porowatość korzeni i aerenchymę, tkankę z dużymi przestworami międzykomórkowymi. Zwiększone natlenianie korzeni pozwala na lepszy transport tlenu do tkanek roślin i dyfuzję tlenu do ryzosfery (radialna utrata tlenu, ROL). Ten fenomen stwarza wąską lecz dobrze natlenioną, hipoksyczną strefę w glebie, gdzie fitotoksyny są utleniane a bakterie metanotroficzne i nitryfikacyjne mogą żyć. Celem badań było określenie zmiany architektury korzeni, porowatości i ROL z korzeni Plantago lanceolata zamieszkujących Małopolski Przełom Wisły. Wybrane gatunki roślin były poddane przejściowemu zalaniu przez 7 dni hodowli na natlenionym i hipoksycznym podłożu. Zaobserwowaliśmy formowanie krótszych korzeni przybyszowych (56-69 mm) niż u roślin kontrolnych (112-196 mm) o dużej porowatości (podłoże niedotlenione 15-21%, kontrolne 8,5-9,4%) a średnica strefy natlenionej (halo) zwiększyła się z wartości kontrolnej na poziomie 0-1,5 mm do 2-2,5 mm w warunkach hipoksycznych.

Opis:: The study aimed to determine the genetic variability in pitch pine (Pinus rigida Mill.) growing in the Niepołomice Forest (southern Poland). In the late nineteenth and early twentieth century, Adolf Cieślar of the Department of Forestry Research in Mariabrunn near Vienna, Austria established the experimental crops of pitch pine. During the study, 227 trees that grew in seven subunits were considered; an analysis of genetic polymorphism using the intersimple sequence repeats (ISSR) technique revealed that pitch pine is genetically variable. The average number of alleles at a given locus for all the pine trees was 1.649, while the effective number of alleles at the loci was 1.435. The value of expected heterozygosity was 0.254, while the percentage of polymorphic loci was 75.30%. The average genetic distance between the examined pines was 0.082. Principal coordinate analysis (PCoA) divided the examined pines into three groups, which was also confirmed by the structure-analysis results of the software STRUCTURE. The resulting division was mainly generated by the SR70 primer, which was indicated to be the primer that differentiated the examined populations of pitch pine. Affiliation of particular trees to selected groups was based on their occurrence in individual crops. This suggests a different origin of the seeds used to establish the research plots of pitch pine in the Niepołomice Forest.
