    Opis:
    The rapidly increasing multifarious use of metallic nanoparticles in technology has necessitated evaluation of their impact on environmental, biotic and human health. The present study investigated the effects of different concentrations of bulk and nanosized CuO on seed germination and seedling growth of Ricinus communis in a randomized completely design with four replications. The experimental treatments included four concentrations of bulk CuO (10, 50, 100 and 500 ppm), four concentrations of nanosized CuO (10, 50, 100 and 500 ppm), and the control without CuO. The results indicate that only the weighted germination index and seedling dry biomass of Ricinus communis were significantly affected by the treatments. Other germination characteristics, plumule and radicle length, and seedling fresh weight were not significantly affected by bulk and nanosized CuO concentrations. It can be concluded that bulk and nanosized CuO in this cocentrations not toxic for germination and growth of Ricinus communis.

    Opis:
    The phytoextraction is a process that uses living plants for cleaning up the heavy metals from contaminated soil. The cadmium and lead contamination of soils results from the application of sludge or urban composts, fertilizers, pesticides, motorization, metallurgy, and different technological processes. In industrial terrain the content of cadmium and lead in soils has increased in the recent years. This study was undertaken to evaluate the potential of Amaranthus caudatus L. ‘Atropurpureus’ and Ricinus communis L. ‘Sanguineus Apache’ for phytoextraction of cadmium and lead. Two species of ornament plants, i.e. Amaranthus caudatus L. ‘Atropurpureus’ and Ricinus communis L. ‘Sanguineus Apache’, were planted in drainless containers in a substrate artificially polluted with cadmium and lead in order to evaluate their suitability for phytoremediation of soils or substrates contaminated with these metals. Cadmium was applied at increasing rates of 0, 1, 5 and 10 mg Cd•dm-3 in the form of cadmium sulfate 3CdSO4∙8H2O, while lead was used at 0, 100, 500 and 1000 mg Pb∙dm-3 in the form of lead acetate (CH3COO)2Pb•3H2O. The applied doses of cadmium and lead in the experiment reflected different degrees of soil pollution. After five months of growth it was found that Amaranthus caudatus L. accumulated the biggest concentrations of cadmium and lead in leaves and the lowest concentrations in inflorescences. Ricinus communis L. accumulated the highest concentrations of cadmium in stems, while the lowest concentrations in inflorescences, whereas the biggest concentration of lead was accumulated in inflorescences and the least lead was accumulated in leaves. The biggest reduction of cadmium and lead concentrations after the completion of the experiment was found in substrates, in which Amaranthus caudatus L. was grown. The tested species of ornamental plants may be used in the phytoextraction of cadmium and lead from soils contaminated.
    Fitoekstrakcja jest jedną z metod oczyszczania gleby z metali ciężkich przez wykorzystanie roślin. Zanieczyszczenie gleb kadmem i ołowiem spowodowane jest miejskimi ściekami, miejskimi kompostami, motoryzacją, nawożeniem, pestycydami, metalurgią i różnymi procesami technologicznymi. W glebach terenów przemysłowych w ostatnich latach obserwuje się zwiększanie zawartość kadmu i ołowiu. W podjętych badaniach oceniano potencjał Amaranthus caudatus L. i Ricinus communis L. do fi toekstrakcji kadmu i ołowiu. Dwa gatunki rośli ozdobnych: Amaranthus caudatus L. ‘Atropurpureus’ i Ricinus communis L. ‘Sanguineus Apache’ posadzono w pojemnikach bezodpływowych w podłożu sztucznie zanieczyszczonych kadmem i ołowiem w celu ocenienia ich przydatności do fi toremediacji gleb lub podłoży skażonych tymi metalami. Kadm zastosowano we wzrastających dawkach: 0, 1, 5, 10 mg Cddm-3, w postaci siarczanu kadmu 3CdSO4∙8H2O, natomiast ołów w dawkach: 0, 100, 500, 1000 mg Pb∙dm-3, w postaci octanu ołowiu (CH3COO)2Pb∙3H2O. Zastosowane dawki kadmu i ołowiu w doświadczeniu odzwierciedlają różny stopień zanieczyszczenia gleb. Po pięciu miesiącach wzrostu stwierdzono, że Amaranthus caudatus L. ‘Atropurpureus’ najwięcej kadmu i ołowiu akumulował w liściach a najmniej w kwiatostanach. Ricinus communis L. ‘Sanguineus Apache’ najwięcej kadmu akumulował w łodygach a najmniej w kwiatostanach, natomiast najwięcej ołowiu akumulował w kwiatostanach a najmniej w liściach. Największy ubytek kadmu i ołowiu po zakończeniu doświadczenia stwierdzono w podłożach, w których uprawiano Amaranthus caudatus L. ‘Atropurpureus’. Badane gatunki roślin ozdobnych mogą być wykorzystywane do fi toekstrakcji kadmu i ołowiu z gleb skażonych kadmem i ołowiem.

    Opis:
    Carbon nanotubes act as regulators of plant germination and growth and are able to change the morphology and physiology of plant cells. The castor plant (Ricinus communis L.) belongs to the Euphorbiaceae family and is a very important medicinal plant. The aim of this study was to investigate the effect of 10 different concentrations of multi-walled carbon nanotubes (MWCNTs) (2, 5, 10, 20, 50, 75, 100, 125, 250 and 500 μg · ml–1) alongside the control under laboratory conditions on the germination and growth of castor seedlings. The results demonstrated that the maximum percentage of germination (96.7%) and relative germination percentage (100%) were found in the concentrations of 50 and 100 μg · ml–1, respectively, and the highest germination rate (53.3%) and the mean germination time (4.6 days) was seen in the concentration of 75 μg · ml–1. However, no statistically significant differences were found between the different concentrations in any of the germination factors. In the concentration of 100 μg · ml–1, there was a significant increase in the seedling vigor index I (400) when compared with the concentrations of 5 and 10 μg · ml–1. The maximum seedling vigor index II (11.3) was found in the concentration of 100 μg · ml–1 and was significantly different from the control and all applied concentrations. The length of radicle in the 100 and 125 μg · ml–1 had a significant increase when compared with the control and the concentrations of 10 and 50 μg · ml–1. The maximum seedling length (4.6 cm) was seen in the concentration of 100 μg · ml–1 where there was a significant increase with 10 μg · ml–1. Moreover, in the 100 μg · ml–1 concentration, the largest number of rootlets (8.6) was seen and when compared with the control and concentrations of 5, 10 and 50 μg · ml–1, there was a statistically significant increase. The maximum wet weight (0.3 g) and dry weight (0.1 g) of seedlings were obtained in the concentration of 100 μg · ml–1 and when compared with the control, there was a significant increase. It was found that in all factors related to the growth of seedlings, the concentrations of 10 and 50 MWCNTs had an inhibitory effect on the response index. The MWCNTs concentration of 100 μg · ml–1 was considered as the optimum concentration in the growth stage of castor seedlings.

    Opis:
    Biodiesel is a clean, renewable, biodegradable, environmentally benign, energy efficient and diesel substituent fuel used in diesel engine. It provides a feasible solution to the twin crises of fossil fuel depletion and environmental pollution. It is produced from renewable sources such as vegetable oils or animal fats by trans-esterification. Although this fuel has gained worldwide recognition for many years, it is not being widely commercialized like petroleum diesel in the world, not widely produced and used especially in our country Ethiopia. Analysis of fatty acid methyl ester composition of the biodiesel produced from castor oil was done with the help of GC-MS and 8 fatty acid methyl esters were identified. Acid and base catalyzed methods were used in the synthesis of biodiesel from castor seed oil. In addition to this the variables that affect the amount of methyl ester yield were determined and an optimum of 96.7 % fatty acid methyl ester (FAME) conversion was obtained at a methanol to oil molar ratio of 6:1, 1.0 % mass NaOH, 65 °C reaction temperature and 3 hour reaction time. The energy content of the oil and biodiesel were 39 MJ/Kg and 40.7 MJ/ Kg respectively which is determined by bomb calorimeter. Other physicochemical properties of the biodiesel were determined and all these lie within the ASTM and EN biodiesel standards except kinematic viscosity. Therefore, castor seed oil methyl ester could be used as an alternative energy resource in diesel engine by blending with petroleum diesel.

    Opis:
    Invasive alien species are non-native plant species that displace native species and pose adverse effects to environment, ecosystem, economy, and human health by diminishing the growth of native plants and by exhibiting higher stress tolerance. In our present study, four invasive alien species, namely Lantana camara, Parthenium hysterophorous, Ricinus communis, and Ageratum conyzoides, were studied from different locations. Plants growing under natural environmental conditions were sampled at random in the vicinity of Jalandhar. To gain insights into the biochemical basis of invasiveness of these plants, the samples were subjected to chemical fingerprinting by using UV-Vis, fluorescent, and Fourier transform-infrared (FT-IR) techniques under natural abiotic stress conditions (moderate and hot conditions). Indices of oxidative stress, such as malondialdehyde (MDA), were also studied. MDA levels were enhanced under hot conditions. Elevated peaks (major and minor) were observed in UV fingerprinting during adverse abiotic conditions. Fluorescent spectroscopy also validated the enhanced levels of secondary metabolites. FT-IR spectroscopy confirmed the presence of alkaloids and phenolics during stress conditions. Peaks were identified as rutin, vanillic acid, ascorbic acid, and glutathione reduced. The obtained results showed that under stressful conditions, the studied plants may produce an increased level of metabolites that might play a role in minimizing the oxidative stress faced by these plants. It was concluded that the studied plants, namely P. hysterophorus, L. camara, R. communis, and A. conyzoides, have the potential to cope with abiotic stress such as high temperature, which could be the reason for their invasiveness and vast adaptability.
