Opis:
To fertilize both grassland and turf lawns waste materials, including the substrate after mushroom cultivation have been used recently. The aim of this study was to determine the effect of the mushrooms substrate to change the amount of root mass of five turf lawns with varying precipitation of perennial ryegrass. Field experiment was established in 2004 in the agricultural station of University of Natural Science and Humanities in Siedlce. In the research, the following factors were used: 1) dose of mushroom substrate, 2) the mixtures lawns with different species composition and participation of perennial ryegrass. Within two years of research the evaluation of the amount of root mass of turf lawns were done. This assessment was made after plants’ vegetation in 2005 and 2006. The roots sampling of lawns were taken. After cleaning of the root and drying at 1050C, the mass was determined by weighing. The largest mass of roots (average from the study years and substrate doses) was observed for the two-component mixture (M1) with 80% share of perennial ryegrass, and the smallest for five-component mixture (M5), where the share of perennial ryegrass was 40%. The average for research years of and mixtures type, indicates that most of the root mass formed the turf lawns with the largest mushroom substrate doses, but at least on the control object. The majority of the tested lawn mixtures, with the exception of mixture five (M5) produced a greater mass of roots in the second year (2006) than in the first (2005) year, despite worse weather conditions.

Opis:
Fodder nutritive value of permanent grassland is dependent on the concentration of individual nutrients, the degree of digestibility and energy concentration. In a grassland study on the base crude fiber content and relevant conversion formulas, digestibility of dry matter and net energy concentration of the feed can be calculated, without the need for specialized equipment. The aim of the study was to determine the effect of mushroom substrate and farmyard manure supplemented NPK, on the digestibility and energy concentration in the sward of permanent meadows in three-year field experiment. In the study, overall digestibility and net energy concentration of feed derived from permanent grassland remained at a high level. Overall digestibility of yield dry matter of grass varies significantly, depending on the collected cuts and year of study, while the net energy concentration did not show differences under the influence of experimental factors studied. Mushroom substrate used in the experiment (alone and completed mineral NPK) caused no significant effect on the digestibility and net energy concentration of the tested feed with regard to both the farmyard manure used as standard and with NPK.

Opis:
The study was conducted in the years 1999–2001 in a meadow with the following fertilizer combinations: control object (without fertilizer), NPK mineral fertilization, fertilizing with manure, manure with NPK fertilization, fertilizing with spent mushroom substrate; spent mushroom substrate with NPK fertilization. The aim of the study was to determine the effect of permanent grassland fertilization both with spent mushroom substrate and the one supplemented with NPK on the up taking of manganese, copper and zinc by the meadow sward. After the cultivation of mushrooms, in comparison to the standard manure, the substrate used in the experiment was characterized by more than twice higher amount of manganese and zinc. However, the amount of copper in the organic materials was similar. In spite of having supplied lager amount of manganese, zinc and similar amount of copper to the mushrooms substrate, it caused the reduction of the uptake of the elements in the meadow sward. In spite of supplying larger amounts of manganese, zinc and copper the reduction of their up taking by meadow sward was observed in comparison to manure mushroom substrate. This may be connected with a slightly alkaline reaction of the soil environment, thus limiting the uptake of the studied micronutrients.

Opis:
A study on the cultivation of Festulolium braunii cv. ‘Felopa’ was carried out using polyurethane rings with a diameter of 36 cm and a height of 40 cm, which were sunk into the ground to a depth of 30 cm and filled with soil material. In this experiment, Kelpak SL was used as a bioregulator. It consists of natural plant hormones such as auxins (11 mg in dm3) and cytokinins (0.03 mg in dm3). The experimental factors were as follows: A1-control; A2 – 20% solution of the growth regulator; A3 – 40% solution; and A4 – 60% solution. The preparation was applied to all three regrowths in the form of spray, at a rate of 3 cm3 ring-1, at the stem elongation stage. The full period of this experiment was in the years 2010–2011. During this time, detailed investigations were carried out on aboveground biomass yield (g DM ring-1), number of shoots (pcs ring-1), leaf blade length (cm), width of the leaf blade base (mm), leaf greenness index (SPAD). The study showed a significant effect of the growth regulator on the formation of Festulolium braunii biomass. However, its highest effectiveness was observed when the 60% solution was applied.
Badania dotyczące uprawy Festulolium braunii ‘Felopa’ przeprowadzono w pierścieniach poliuretanowych o średnicy 36 cm i wysokości 40 cm, które wkopano na głębokość 30 cm i wypełniono materiałem glebowym. Czynnik doświadczalny stanowił bioregulator o nazwie handlowej Kelpak SL, w skład którego wchodzą naturalne hormony roślinne tj. auksyny (11 mg × l-1) i cytokininy (0,03 mg × l-1). Obiekty doświadczalne: A1 – kontrola oraz z roztworem bioregulatora A2 – 20%, A3 – 40% i A4 – 60%. Preparat aplikowano na trzy odrosty roślin w formie oprysku, w dawce 1cm3· pierścień-1, w fazie strzelania w źdźbło. Okres pełnego użytkowania obiektów doświadczalnych przypadał na lata 2010–2011. W tym czasie szczegółowymi badaniami objęto plon biomasy nadziemnej (g s.m·pierścień-1), liczbę pędów (szt × pierścień-1), długość blaszki liściowej (cm), szerokość podstawy blaszki liściowej (mm), indeks zieloności liścia (SPAD). Przeprowadzone badania wykazały istotny wpływ bioregulatora na kształtowanie się biomasy Festulolium braunii. Największą jego skuteczność odnotowano stosując opryski 60% roztworami.

Opis:
Nowadays, substances stimulating the growth and development of different agricultural plant species are used in intensive farming. Some of such plant growth regulators are Asahi SL and Moddus 250-EC. So far the literature dealing with growth regulators has focused mainly on their effects on deciduous trees. Because no data are available on how those substances affect conifer trees, this paper presents description of experiments on the effects of Asahi SL and Moddus 250-EC on the increase of tree height and branch length of Picea pungens and Thuja occidentalis. The research has proved that morphological features of the plants tested in the experiment varied according to which growth regulator was used and in what month the measurements were taken. Conifer trees sprayed with Asahi SL had a bigger yearly height growth rate and bigger growth of branches than those sprayed with the stimulator Moddus 250-EC.

Introduction and objective: Polycystic ovary syndrome (PCOS) is one of the most frequent reasons for anovulation in infertile women. It can affect 5% – 10% of women of reproductive age. One of the important factors associated with the typical clinical signs and hormonal disorders could be insulin resistance and hyperinsulinaemia. The primary objective of this study was to assess the prevalence of insulin resistance in PCOS women. The secondary objective was to evaluate changes in body mass index (BMI), waist-to-hip ratio (WHR), and insulin sensitivity after 3 months of metformin therapy Materials and methods: 68 patients were enrolled in the study. In all participants fasting and 2-h post-load glucose and insulin levels, WHR and BMI were evaluated before and after metformin (2 x 850 mg) therapy. Insulin resistance was assessed using G0/I0, G120/I120, and HOMA-IR indexes Results: Before the treatment, insulin resistance was observed in 26% patients according to HOMA-IR, and in 16% or 28% according to G0/I0 or G120/I120, respectively. Metformin therapy was associated with improvement in insulin sensitivity in HOMA-IR and G120/I120 defined insulin resistant patients. Conclusions: The percentage of insulin resistant PCOS patients differed depending on the method applied. It is necessary to find a single most useful method to measure insulin resistance. Metformin treatment significantly improves insulin sensitivity in insulin resistant patients.

Opis:
Research was carried out in years 2007-2009 on the basis of field experiment in split-plot design, in three repetitions. Monoculture lawn was set up for the experiment. In pure sowing, four species of lawn grass were studied: perennial ryegrass, red fescue, common meadow-grass, and common bent. In the experiment, the following factors were applied: bedding type: a – no hydrogel „0” – control plot; b – with the addition of hydrogel at the depths of 5 cm, 10 cm, and 15 cm; soil cover: a – cultivated soil (P); b – horticultural peat (T). At the end of each growth period, turf samples with root systems were collected from the plots at the depth of 10 cm. On their basis, the assessment of root dry matter was carried out and the number of roots was calculated on each turf block. In the particular research years, both the number of shoots and root mass formed by the studied monoculture lawns were diversified in relation to the bedding type. In the first research year, on the bedding with 5 cm depth of hydrogel placement, the studied monocultures formed the highest root mass, and in the second year the highest shoot number. Horticultural peat cover in both research years increased both the number of shoots and the root mass of the studied monoculture lawns.
Badania realizowano w latach 2007-2009 na podstawie doświadczenia polowego prowadzonego w układzie split-plot, w trzech powtórzeniach. W tym celu założono trawnik monokulturowy. W siewie czystym badano cztery gatunki traw gazonowych: życicę trwałą, kostrzewę czerwoną, wiechlinę łąkową i mietlicę pospolitą. W doświadczeniu zastosowano następujące czynniki badawcze: 1) rodzaj podłoża: a – bez hydrożelu „0” – kontrola; b – z dodatkiem hydrożelu umieszczonego na głębokości: 5; 10; 15 cm; 2) okrywa glebowa: a – gleba uprawna (P); b – torf ogrodniczy (T). Pod koniec każdego okresu wegetacji z poletek pobierano próbki darni wraz z systemem korzeniowym na głębokość 10 cm. Na ich podstawie dokonywano oceny suchej masy korzeni oraz na każdym krążku darni wyliczono liczbę pędów. W poszczególnych latach badań zarówno liczba pędów, jak i masa korzeniowa wytworzone przez badane murawy monokulturowe były zróżnicowane w odniesieniu do rodzaju podłoża. W pierwszym roku badań na podłożu z 5 cm głębokością umieszczenia hydrożelu badane monokultury wytwarzały największą masę korzeniową, a w drugim – liczbę pędów. Okrywa z torfu ogrodniczego w obu latach badań korzystniej wpływała zarówno na liczbę pędów, jak i masę korzeniową testowanych muraw monokulturowych.

Opis:
The aim of study was to compare the effects of two growth regulators on selected mor-phological features of yellow pine. In April 2012, 9 plants of yellow pine Lawson variety were planted to the soil. In April 15, 2013 a research agent in a form of following growth regulators: Asahi SL and Moddus 250-EC was introduced. There were the following experimental objects: C – control (only water spraying), As – Asahi spraying, Md – Moddus spraying. The tested features were: increase in plant height (cm), the increase in needle length (cm) of yellow pine. Measurements of increases in length of needles were made in each case on the same specially marked parts of the plants and performed on 27th of each month from beginning of May to ending of September. Among the used of growth regulators the greatest influence on the height increase of the tested trees as well as on the needle length of yellow pine more affected regulator Moddus. The largest total increase in the needles length of yellow pine was on the object with Modus and Asahi, and on control object it was significantly lower than on objects with growth regulators.

Opis:
In a pot experiment conducted in a greenhouse, the effect of CCC Bercema growth inhibitor to reduce vegetative shoot growth of perennial ryegrass and cocksfoot was studded. The experiment was set up in triplicate. Growth regulator was applied once, in a form of an aqueous solution. The following experimental objects were specified: control object, Bercema with a concentration of 10%, 20% and 30%. Ten measurements were performed every 3 days. The study was conducted under conditions of 12-hour artificial light daily. The results were statistically analyzed using two-factorial variance analysis . It was found that the greatest shoot growth reduction of ryegrass due to the highest inhibitor concentration (B- 30%), but for cocksfoot under the influence of the minimal concentration (B- 10%), compared to the control object. It has been noted that cocksfoot is more sensitive to the applied growth regulator, resulted in significantly greater inhibition of shoot regrowth than for ryegrass. In the experiment with the perennial ryegrass significant differences in the growth of shoots were found under the influence of inhibitor application at a concentration of 30%, compared to the control object. In the case of cocksfoot, all the concentration increases of Bercema inhibitor significantly differentiated the shoots regrowth.
