Opis:
In this research, the response of the plant Gypsophila arrostii Guss. to boron (B) under in vitro conditions was examined. The seeds were cultured on MS medium including 0, 10, 20, 40, 80 mg B l-1. Seedlings obtained from germinated seeds and grown in a culture medium for 8 weeks were analyzed. At the end of this period, stem length (cm), root length (cm), plant weight (g) and elemental content (mg kg-1) of the plants were determined. According to the results, the seeds of G. arrostii Guss. could germinate on media with up to 80 mg B l-1, and the seedlings demonstrated an ability to survive, albeit poorly, a dose of boron as high as 80 mg B l-1. In the experiment, the highest stem length (7.5 cm) was obtained from the 20 mg B l-1 treatment and the highest stem fresh weight (0.9 g) and stem dry weight (0.19 g) were measured in the 10 mg B l-1 variant. No significant statistical difference was determined between the boron treatments in terms of root length, root fresh weight and root dry weight. Our evaluation of the elemental content of plants demonstrated that the amount of boron in the root and stem increased parallel to its increase in the growth media. In the 80 mg B l-1 treatment, 601.9 mg kg-1 boron in root and 1,035.4 mg kg-1 boron in stem were determined. Besides, it was discovered that the contents of K, Mg, Zn, Na in root decreased while the contents of P, B, Mn, Cu in root increased in response to the growing amount of boron in the environment. In response to the increasing boron concentrations, the content of K, P, Mn, Cu, Zn and S increased while the amount of Ca, Mg and Na in the plant stem decreased. Consequently, G. arrostii Guss. was found to be a boron hyperaccumulator, collecting boron in tissues (in the roots and stems), in which it resembled some other types of Gypsophilla.

Opis:
Competitive interactions are common in plant communities, but the underlying mechanisms and effects of competition have not been fully elucidated to date. A pot experiment (3 series in 2009- 2011) was conducted to evaluate the effect of a sowing method of spring barley and Italian ryegrass, and different water condition on the nitrogen (N) content and accumulation in the aerial biomass of plants at different stages. The experimental factors were as follows: 1) sowing regime – pure sowing and mixed sowing – spring barley undersown with Italian ryegrass, 2) water supply – plants supplied with water to meet their full requirements and 50% water supply reduction. The N content of the aerial biomass of plants was determined at five phenological development stages of spring barley grown in a pure stand under optimal soil moisture conditions: leaf development, tillering, stem elongation, heading and ripening. Nitrogen uptake was determined based on the N content and dry matter accumulation in plants. Nitrogen concentrations in the aerial biomass of barley and ryegrass varied throughout the growing season. Nitrogen content was particularly high in leaves, and it decreased steadily during plant development. Neither the sowing regime nor the water supply exerted significant effects on the N content of the aerial biomass of spring barley. In Italian ryegrass, under optimal water supply, mixed sowing with spring barley decreased N concentrations in shoots only during tillering. In spring barley, mixed sowing reduced N uptake by biomass, and the observed decrease was exacerbated under water deficit. In Italian ryegrass, reduced water supply decreased N uptake, but the effect of competitive interactions between the analyzed species was usually stronger than the influence of water deficit. Differences in N accumulation in aerial biomass were determined by the amount of biomass produced in mixed stands and the responses of barley and ryegrass to water deficit.

Opis:
Copper is an essential trace element in living organisms, but its excess interferes with metabolic transformations in plant, animal and human cells. The uptake of copper from contaminated soils can be regulated, for example, by soil liming or application of other substances which enhance soil adsorption capacity and Cu binding in the substrate. The purpose of this study has been to assess the response of maize to soil contamination with copper depending on the applied neutralizing substances. The tested factors were increasing concentrations of Cu in soil: 0, 200, 400 and 600 mg Cu kg ?1 dm, and soil application of mineral (lime, loam and zeolite) and organic (manure, peat and bark) neutralizing substances. Soil contamination with copper within the range of 200 to 600 mg kg ?1 of soil caused reduction in maize yields. Positive influence such as alleviation of the harmful effect of copper contamination was demonstrated by lime and manure, which enhanced yields of maize, especially in the series polluted with 200 and 400 mg Cu kg ?1 . The other soil amending substances, especially peat added in amounts of 400 and 600 mg kg ?1 of soil, caused aconsiderable depression in maize yields. A linear dependence has been demonstrated between the concentration of Cu in maize plants and the content of Cu in the substrate, with the root content of Cu being on average six-fold higher than in aerial organs. Mineral soil amendments significantly decreased the BTC index in maize compared to organic substances, and lime as well as pine bark decreased the BCF index to 2.33 and 1.67 versus the value of 4.21 found in the control treatment without any neutralizing substances. The uptake of copper depended on the volume of yield and ? to a lesser degree ? on the concentration of Cu in plants. The uptake of copper by plants was the highest in treatmentscontaminated with a rate of 200 mg Cu kg ?1 , which was the consequence of higher yields from that treatment than from the plots polluted with 400 or 600 mg Cu kg ?1 of soil.
