Opis:: For several decades an increase of platinum in the environment was recorded. This is connected with the release of platinum from automobile catalytic converters and pharmaceutical industries. In the conducted experiments the effect of various forms and concentrations of platinum on the germination and roots growth of different plants (oat, garden cress and tomato) was investigated. Two separate experiments were performed with lower (experiment 1st: 1, 5 and 10 mg/L) and higher (experiment 2nd: 10, 20 and 40 mg/L) [Pt(NH3)4](NO3)2 or PtCl4 dosages. There was no significant effect of dose and form of platinum on the germination of seeds (experiment 1st and 2nd). The effect of platinum containing substances dose on root growth of young seedlings was observed during experiment, dependent on the species of tested plants. The root length of oat plants was similar in all treatments in experiment 1st. The shortest tomato roots were observed in the case of a 10 mg/L of PtCl4, it was statistically shorter than the control plants (treated with water) as well. The roots of the tomato treated with [Pt(NH3)4](NO3)2 were the same length as observed for the control sample. The garden cress root growth was not affected by [Pt(NH3)4](NO3)2, but a solution containing Pt4+ stimulated the root growth. The roots of tomato and oat treated with [Pt(NH3)4](NO3)2 had similar length as the control plants in contrast to the far shorter roots treated with PtCl4 (experiment 2nd). Moreover, the treatment with [Pt(NH3)4](NO3)2 stimulated the growth of garden cress roots compared to the control, while only the lowest dose of PtCl4 stimulated the root growth.

Opis:: The root system architecture (RSA) displays complex morphological characteristics because of diverse root growth behaviors. Recent studies have revealed that swarming behavior among roots is particularly important for RSA to adapt to environmental stimuli. However, few models are proposed to simulate RSA based on swarming behavior of roots. To analyze plasticity of RSA affected by swarming behavior, we propose viewing it as a swarm of single roots. A swarming behavior model is proposed by considering repulsion, alignment, and preference of individual single roots. Then, the swarming behavior model is integrated into a simple and generic RSA model (called ArchiSimple). Lastly, characteristics of RSA affected by swarming behavior model and non-swarming behavior model are compared and analyzed under three different virtual soil sets. The characteristics of RSA (such as primary root length, lateral root length, lateral roots, and resource uptake) are significantly promoted by swarming behavior. Root system distributions can also be greatly affected by swarming behavior. These results show that root foraging and exploration in soil can be regarded as collective behavior of individual single root.

Opis:: The aim of the study was to determine the effect of various biopreparations on the growth of the apple root system, the number of spores of AMF, the total number of bacteria and microscopic fungi in the rhizosphere soil, and the degree of mycorrhizal association in the roots of two apple tree cultivars. The experiment was established in the spring of 2009 in the Experimental Orchard of the Institute of Horticulture in Dąbrowice. The research objects were one-year-old maidens of the apple cultivars ‘Topaz’ and ‘Ariva’ grafted on M26 rootstock. The trees were treated with the following biopreparations: control, control NPK (standard NPK fertilization), manure, Micosat F + manure, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + manure, BioFeed Quality + manure, Tytanit + manure, Vinassa + manure, Florovit Eko, and Florovit Pro Natura. Treatment of ‘Topaz’ and ‘Ariva’ apple trees with the biopreparations Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eko and Florovit Pro Natura produced positive effects on the growth of apple roots and their mycorrhizal frequency, and the size of the populations of microorganisms in the rhizosphere soil.
Celem badań było określenie wpływu różnych biopreparatów na wzrost systemu korzeniowego, liczbę zarodników grzybów mikoryzowych, ogólną liczbę bakterii i grzybów mikroskopowych w glebie rizosferowej oraz stopień asocjacji mikoryzowej w korzeniach dwóch odmian jabłoni. Doświadczenie założono wiosną 2009 r. w Sadzie Doświadczalnym Instytutu Ogrodnictwa w Dąbrowicach. Obiektem badań były jednoroczne okulanty jabłoni odmian Topaz i Ariva szczepione na podkładce M26. Rośliny traktowano następującymi biopreparatami: kontrola, kontrola NPK, obornik, Micosat F + obornik, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + obornik, BioFeed Quality + obornik, Tytanit + obornik, Vinassa + obornik, Florovit Eco oraz preparat Florovit Pro Nature. Traktowanie drzew jabłoni ‘Topaz’ i ‘Ariva’ biopreparatami Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eco oraz Florovit Pro Nature wpłynęło korzystnie na wzrost korzeni, stopień frekwencji mikoryzowej i wielkość populacji mikroorganizmów w glebie rizosferowej.

Opis:: The aim of this study was to investigate the phytotoxic effects of seven metal ions (Cd(II), Cr(VI), Cu(II), Hg(II), Ni(II), Pb(II) and Zn(II)) on length of roots of five rapeseed (Brassica napus L. subsp. napus) cultivars registered in Slovakia (Atlantic, Baldur, Californium, Oponent and Verona). The phytotoxic effect of metals was evaluated using IC50 values. The studied metal ions inhibited germination and root growth of rapeseed seedlings. In general, the toxicity of metal ions decreased in the following order Cu > Cr >Hg > Cd > Pb > Ni > Zn. Atlantic, Baldur and Californium were more sensitive to Cd than to Ni, for Oponent and Verona higher toxicity exhibited Ni. From the studied rapeseed cultivars Atlantic and Californium were found to be most sensitive to tested metals. On the other hand, high tolerance to metal treatment was determined for Baldur. Czech cultivar Opponent showed high tolerance to Cd, Cr, Cu and Pb, but it was sensitive to Hg and Ni. The above-mentioned results confirmed differences in the metal tolerance of tested rapeseed cultivars.
