“…This fact can be attributed to organic matter decomposition and absorption of the nutrient by the plant, which showed intense growth rate along the entire cycle, besides the migration of the element to other chemical forms in the biosolid. As already mentioned, Zhang et al (2010) report that plants of the genus Pennisetum have great capacity of Zn phytoextraction.…”

“…After this period, there was a decrease in the Zn content, which can be associated with the greater absorption by P. purpureum. Alvarenga (2015) highlights that the highest leaf biomass production of this species occurs at 139 days of cultivation in biosolid and Zhang et al (2010) report that plants of the genus Pennisetum exhibit great capacity of Zn phytoextraction, which can partially justify its reduction in the exchangeable form.…”

A B S T R A C TIn order to reduce the effect of heavy metals on the biosolid, it is necessary to promote its phytoremediation. It is important to know the total content and chemical forms of these elements in the residue for analyzing its behavior and potential toxicity. Thus, the aim of this study was to evaluate the fractionation and behavior of Cu and Zn in biosolid cultivated with Pennisetum purpureum in different periods. The experiment was carried out using a randomized complete block design. The treatments, with five replicates, corresponded to Pennisetum purpureum cultivation in biosolid for 30, 60, 90, 120 and 150 days after planting. The total contents of Cu and Zn in the biosolid remained below the critical limits established by the CONAMA Resolution 357, and there was a reduction in these values with Pennisetum purpureum cultivation. Furthermore, the increment in the grass cultivation period caused intense reduction of Zn contents bound to organic matter, but there was an increase in soluble Zn and residual Zn. Additionally, there was an intense reduction in the content of Cu bound to sulfides. Therefore, for biosolid phytoremediation purposes, the grass should be cultivated for 150 days.Fracionamento de cobre e zinco em biossólido cultivado com Pennisetum purpureum em diferentes períodos R E S U M O Para atenuar o efeito da presença de metais pesados no biossólido, faz-se necessária a sua fitorremediação, sendo fundamental o conhecimento das concentrações totais e das formas químicas destes elementos no resíduo para fins de análise do seu comportamento e potencial toxicidade. Assim, objetivou-se avaliar o comportamento e fracionamento do Cu e Zn em biossólido cultivado com Pennisetum purpureum em diferentes períodos. O experimento foi realizado utilizando-se delineamento em blocos casualizados. Os tratamentos, em cinco repetições, corresponderam ao cultivo de Pennisetum purpureum em biossólido por 30, 60, 90, 120 e 150 dias a partir do plantio. As concentrações totais de Cu e Zn no biossólido ficaram abaixo dos limites críticos da Resolução CONAMA 375, havendo redução destes valores com o cultivo de Pennisetum purpureum. Além disso, o incremento do período de cultivo da gramínea causou intensa redução da concentração de Zn ligado à matéria orgânica; por outro lado, houve aumento do Zn solúvel e residual. Já para o Cu houve intensa redução da concentração do elemento ligado a sulfetos. Assim, para fins de fitorremediação do biossólido, recomenda-se o plantio da gramínea por 150 dias.

“…They belong to the so-called hyperaccumulators, which have been found to accumulate large amounts of heavy metals [3][4]. It is recommended that phytoremediation of soils contaminated with heavy metals be carried out using plant species of different applications, including grasses and energy crops [5][6][7].…”

The aim of our research was to assess the effectiveness of phytoextraction of heavy metals from sewage sludge by 'Rubik' and 'Albik' varieties of Jerusalem artichoke. The 6-year field experiment involved four levels of fertilization with sewage sludge at doses of 0,10,20,40, . The research evaluated the amount of Jerusalem artichoke yield as well as the uptake and use of heavy metals by the Jerusalem artichoke varieties.It was established that increasing doses of sewage sludge had significantly increased the yield of the Jerusalem artichoke varieties. Increasing doses of sewage sludge also had a significant effect on the increase in the content of heavy metals in aboveground parts of plants. The highest heavy metal uptake with the yield of the Jerusalem artichoke varieties was observed at a dose of 60 Mg DM • ha -1. Among the tested varieties of Jerusalem artichoke, Albik had higher yield, higher content and uptake of heavy metals, and greater recovery of these elements as compared to Rubik. Therefore, based on the obtained research results, Albik can be recommended for phytosequestration of heavy metals from sewage sludge amended soil.

“…Silphium perfoliatum L. is a perennial, tall, yellow flowering C 3 plant, characterized by a wide range of valuable practical traits and has been cultivated as a medical, melliferous, fodder, ornamental, and reclamation plant (Niqueux, 1981;Neumerkel and Märtin, 1982;Troxler and Daccord, 1982;Daniel and Rompf, 1994;Kowalski and Wolski, 2005;Kowalski and Kędzia, 2007;Zhang et al, 2010). In recent years, S. perfoliatum L. has been of interest as an energy crop, especially for biogas production (Vetter et al, 2010;Bauböck et al, 2014;Mast et al, 2014;Gansberger et al, 2015).…”

SummarySilphium perfoliatum L. is a perennial and flowering crop that has been investigated in recent years for its potential as an energy plant, particularly for biogas production. A stand establishment by sowing of seeds is complicated, owing to the low germination capacity of untreated S. perfoliatum L. seeds. Consequently, germination experiments were carried out with two-to four-factor levels to determine the effect of selected factors (medium, pretreatment, light, temperature, prechilling) on dormancy and germination of S. perfoliatum L. seeds and to achieve maximum germination rate. All factors had a highly significant effect on germination. Germination experiments displayed a primary and physiological dormancy. Germination could be significantly increased by using a 0.05% GA 3 solution during the imbibition phase, a light-dark cycle, alternating temperatures between 20°C and 30°C, and a wet stratification for seven days at 0°C. The experiments helped to fully exploit the germination potential and to develop a germination test method for S. perfoliatum L.Keywords: bioenergy, cup plant, dormancy, seed production, seed treatment ZusammenfassungSilphium perfoliatum L. ist eine ausdauernde und blühende Pflanze, die in den letzten Jahren hinsichtlich ihres Potentials als Energiepflanze für die Biogasproduktion untersucht wurde. Eine gesicherte Bestandesbegründung mittels Saat ist aufgrund der geringen Keimfähigkeit von unbehandelten S. perfoliatum L.-Samen schwierig. Folglich wurden Keimversuche mit zwei bis vier Faktorstufen durchgeführt, um die Wirkung ausgewählter Faktoren (Medium, Vorbehandlung, Licht, Temperatur, Vorkühlung) auf die Dormanz und die Keimung von S. perfoliatum L.-Samen zu bestimmen und die maximale Keimfähigkeit zu erreichen. Alle untersuchten Faktoren hatten einen signifikanten Effekt auf die Keimung. Die Keimfähigkeitsversuche ergaben eine primäre und physiologische Dormanz. Die Keimfähigkeit wurde durch den Einsatz einer 0,05% GA 3 -Lösung während der Quellungsphase, eines Licht-und Dunkelwechsels, einer alternierenden Temperatur zwischen 20 und 30°C und einer nassen Stratifikation von sieben Tagen bei 0°C signifikant erhöht. Damit wurde das Keimfähigkeitspotential ausgeschöpft und eine Keimfähigkeitsprüfmethode für S. perfoliatum L. entwickelt.
