Opis:: This study investigates cadmium (Cd) accumulation in the plant leaves of juglans regia (walnut) and cydonia oblanga (quince) trees related to traffic emissions on the highway roadside. The plant leaf samples were collected from 20 sites on the D-100 Highway roadside and washed with deionized water before analyzed. Determination of Cd was carried out using an inductively-coupled plasma-mass spectrometer after microwave digestion of the samples. Cd concentration on the plant leaves was found to be between 0.04–0.11 mg/kg. In order to determine the traffic-based emissions, vehicles were counted and an emission inventory was prepared. 0.18 tons of Cd was found to be delivered into the atmosphere every day. Cd accumulation depends on traffic density because there were no residential area and industrial plants. The distribution of Cd accumulation caused by traffic emissions was mapped by using a geographic information system (GIS). The maps showed that the Cd accumulation was high in the areas near the highway and then gradually decreased by moving away from the highway.

Opis:: The aim of the study was to investigate how the foliar application of iodine, as well as its concentration in the working liquid, influence the growth of fresh and dry weight of plants, stems, leaves, roots and number of shoots and leaf laminae of sand Lucerne. The experiment was carried out in vases. The three plants that developed the largest number of leaves in the vase were left. The experimental factors as the plant growth regulator with the trade name Stymjod in three concentrations of 1.5%, 3% and 4.5% in the working liquid were introduced; the control involved distilled water. Two plant applications were performed. The first one in 6 appropriate leaf phase and the second in the branching formation phase. A single dose of the working liquid was 50 ml per vase. This dose of liquid caused the complete sprinkling of plants in a vase. The obtained results were statistically analyzed by means of analysis of variance. The experiment showed that the concentration of Stymjod in the working liquid is very important. It is difficult to say which concentrations gave the best results in cultivating sand lucerne. The present studies demonstrated that Stymjod applied foliarly at 4.5% concentration significantly affected the growth of stems and leaf blades. Additionally, 1.5% concentration increased the weight of fresh matter and dry matter of roots. The experiment showed that the effects of Stymjod application to hybrid alfalfa depended on its dose. It is difficult, however, to clearly state which concentration produced the best results so further research in this area is needed.

Opis:: At present, there are burning issues concerning waste utilization of the agro-industrial complex, rational usage of nature and transition to the use of environmentally friendly and low-waste technologies. One of the most forward-looking areas is the application of the principles of the so-called "green chemistry", in particular, the development of technological processes using renewable raw materials and chemicals, the chemicals with a short half-life and low cost while ensuring maximum efficiency. The article presents the results of antigiberrelic preparation effect, which is characterized by low dosage and half-life in soil from 3 to 43 days on productivity, growth processes, anatomical, morphological features and functioning of the leaf apparatus of white mustard plants and rapeseed. The research shows that CCC-750 reduced the height of mustard and rapeseed plants. Inhibition of growth processes of white mustard plants at the beginning of the flowering phase with an anti-gibberellic preparation led to increased stem branching, which, in its turn, resulted in an increase in the number and area of leaves throughout the growing season. Moreover, the use of quaternary ammonium salt on winter rape plants has led to a reduction in the number of leaves and leaf area in comparison to the control samples. The application of the retardant caused an increase in the productivity of the studied cultures due to the increase in the number of pods, the increase in the mass of thousands of seeds and the number of seeds in the pod.

Tytuł:: Dynamika wzrostu roślin pszenżyta ozimego odmian Woltario i Krakowiak w zależności od gęstości siewu

Opis:: Badania przeprowadzono na mikropoletkach w Puławach z odmianami pszenżyta ozimego — Woltario półkarłowego i Krakowiak o normalnej długości słomy. Uwzględniono trzy gęstości siewu- 2, 3, 4 mln ziaren/ha. W początkowych fazach wzrostu określono liczbę pędów, liści i suchą masę rośliny. W fazie 2-go kolanka rośliny odmiany Woltario, wymagającej rzadkiego siewu, w warunkach zwiększania odległości roślin w rzędzie, miały większą liczbę pędów, liści i wyższą suchą masę w porównaniu do roślin odmiany Krakowiak wymagającej gęstego siewu.
The investigations were carried out in microplots located in Puławy. Two cultivars of winter triticale: Woltario and Krakowiak were sown. The cultivars differ in their requirements as regards the sowing density. Plants of cv. Woltario need rather sparse sowing, whereas plants of cv. Krakowiak find better growing conditions at dense sowing. Three rates of sowing density were applied in the experiment: 2, 3 or 4 mln grains/ha. Number of stems per plant, number of leaves from one plant and plant dry matter were assessed at early growth stages. In cv. Woltario, compared to cv. Krakowiak, the effects of increasing plant-to-plant distance, evaluated at the 2nd node growth stage, were manifested by producing a greater number of stems and leaves. Moreover, the content of dry matter in cv. Woltario plants was higher than that in plants of cv. Krakowiak.

Opis:: Liście morwy białej mają wysoki potencjał prozdrowotny, zwłaszcza dla diabetyków. Zabiegi przetwarzania tego surowca nie są jednak ujednolicone, co skutkuje dużym zróżnicowaniem jakościowym pomiędzy preparatami dostępnymi na rynku. Dokonano wyboru najlepszej formy liści morwy Morus alba odmiany Żółwińska Wielkolistna, pozwalającej na utrzymanie właściwości funkcjonalnych preparatów końcowych, na podstawie analizy ich aktywności przeciwutleniającej. Testom poddano liście ‘całe’, ‘grube’ (rozdrobnienie 50-70 mm x 10-20 mm) i ‘drobne’ (rozdrobnione 30-40 mm x 5-10 mm), które leżakowano (przez 1 lub 4 godziny) i suszono w temperaturze 30, 60 lub 90˚C. Jako najlepsze wskazano preparaty otrzy-mane z liści ‘grubo’ rozdrobnionych.
White mulberry leaves have high pro-healthy potential, especially for diabetics. However, processing procedures of this plant are not standardized. It results in high differentiation between quality of products available on the market. In this paper the selection of the best form of Morus alba cv. Zolwinska Wielkolistna was made. Basing on the antioxidant tests, the health-promoting values of the final preparations, was made. Whole leaves, 'coarse' (50-70 mm x 10-20 mm crushed) leaves and 'fine' (30-40 mm x 5-10 mm crushed) leaves were tested, after further aging (for 1 or 4 hours) and drying (at 30˚C, 60˚C or 90˚C) processes. The preparations obtained from 'coarsely' shredded Morus alba leaves were indicated as the best.
