Opis:: Little is known about the impact of exotic invasive plant species on soil invertebrate communities. The influence of highly productive invader Reynoutria sachalinensis on the soil microarthropods was studied. Three sites, with different coverage of the invader, have been selected in the mixed forest in the Jura Krakowsko-Częstochowska. The lowest abundance of microarthropods and the lowest oribatid species richness were noted in the monospecific Reynoutria infestation stand. The reduction of abundance of saprophagous mites (Oribatida, Acaridida) and springtails were observed at the totally invaded site, whereas gamasid and actinedid mites reacted positively to the presence of Reynoutria. Observed abundances and species richness of microarthropods at studied sites were in accordance with theories on biodiversity. Antifungal activity of phenolic compounds present in leaves of R. sachalinensis may negatively influence on saprophagous representatives of microarthropods. On the other hand, predacious mites profited from the simplified vegetation structure.

Opis:: Accumulation of Cd, Pb, Zn, Cu (HM) by spring barley (Hordeum vulgare L.) from sod podzolic sandy loam and chernozem soils, impacted by heavy metals pollution in the soils, is studied in the article. The aim of study has been to determine spring barley bioaccumulation capacity impacted by the HM pollution with the high level of Cd, Pb, Zn, Cu concentration in soils. The HM concentration diapason caused biomass reduction – the scope of toxic tolerance was obtained. The range of contaminants concentration in soil, which caused the plant biomass reduction, from the beginning to plants death – the scope of toxic tolerance, is the index of a species reaction on selected xenobiotic. It shows: “threshold” concentration of a contaminant that caused a plant biomass inhibition; toxic process development and the correlation between contaminants concentration in soil and/or plant and the plants inhibition; the concentration that caused the plant death. Spring barley accumulation indexes of the studied metals were calculated. Relevant scopes of the plant-uptake index for each metal were calculated. Dynamics of the toxic process development of spring barley as impacted by the pollution in the break-down by studied metals were observed on two different soils. Toxic process dynamic evaluation gives the possibility to simulate concentration of the trace metal in plants, concentration of available forms of these elements in soils, and also contamination level (content of metals) that caused plants height and plant weight reduction by 10%, 50% and 90%.
Celem pracy było określenie wpływu zanieczyszczenia gleb piaszczysto-gliniastych bielicowych i czarnoziemów przez metale ciężkie (Cd, Pb, Zn, Cu) na bioakumulację tych pierwiastków w jęczmieniu jarym (Hordeum vulgare L.). Podwyższone stężenie metali ciężkich spowodowało spadek plonu biomasy (od 10 do 90%). Stwierdzono, że im wyższe stężenie pierwiastków w glebie tym reakcja negatywna roślin była większa, aż do zamierania roślin. Wyliczono wskaźniki akumulacji dla każdego z pierwiastków metali. Ocena dynamiki procesu zanieczyszczenia gleb przez metale ciężkie (na podstawie wskaźników akumulacji) daje możliwość stymulowania stężenia tych pierwiastków w glebie.

Opis:: Physalis peruviana is one of the most promising tropical fruit plants because of its rapid growth, high yield, and nutritional quality. Th is study was designed to investigate plant development under heavy metal contamination (Cd, Pb) and responsiveness to arbuscular mycorrhizal fungi (AMF) colonization by Rhizophagus clarum and Claroideoglomus claroideum. Th e antioxidant capacity, total lipid content and fatty acid profi le in fruits, accumulation of Cd and Pb in diff erent plant parts, plant dry biomass, and mycorrhizal colonization were determined. As a result of inoculation, a considerable reduction in Cd and Pb in the fruits was observed, compared with non-inoculated plants. Th e fruit number and dry weight increased in plants associated with C. claroideum. Th ese plants also showed higher acid phosphatase activity, root protein accumulation and glomalin production. Th e type of antioxidant defense was AMF strain-dependent. Antioxidant activity and H2O2 neutralization were enzymatic rather than non-enzymatic processes in the fruits of C. claroideum plants compared with those forming an association with R. clarum. Mycorrhizal establishment changed the composition and concentration of fruits’ fatty acids. Th e ratio of unsaturated fatty acids was increased. With respect to the accumulation of bioactive compounds in golden berry the present fi ndings are important for obtaining the optimum benefi ts of mycorrhizal association under unfavorable conditions.
