“…Five of the clones used in Experiments 1 and 2 (namely 'Fondachello', 'Tortorici', 'Cefalú', 'Agrigento' and 'Licata') were collected from the Experimental Fields at University of Catania (Italy) (hereinafter referred as UNICT) (10 m a.s.l., 37°24'N, 15°03'E), and whose sites of origin are reported in Cosentino et al [35]. Two clones (namely 'Martinensis' and 'Granadensis') used in Experiment 1 were collected in different riparian areas of Spain and a commercial clone ('Piccoplant') used in Experiment 1 was provided by a private company (Piccoplant, Oldenburg, Germany).…”

Perennial rhizomatous grasses are regarded as leading energy crops due to their environmental benefits and their suitability to regions with adverse conditions. In this paper, two different experiments were carried out in order to study the salinity (S) and water stress (WS) effects on biomass production in giant reed (Arundo donax L.). In Experiment 1, eight clones of giant reed were subjected to four S and WS treatments: (i) well-watered with nonsaline solution, (ii) water stress with non-saline solution, (iii) well-watered with saline solution and iv) water stress with saline solution. In Experiment 2, five clones of giant reed were subjected to increasing S levels in two locations: University of Catania (UNICT-Italy) (i)well-watered with non-saline solution and (ii)wellwatered with mild saline solution; and University of Barcelona (UB-Spain) (iii)well-watered with non-saline solution and (iv)well-watered with severe saline solution. Photosynthetic and physiological parameters as well as biomass production were measured in these plants. According to our data, giant reed seems to be more tolerant to S than WS. Both stresses mainly affected stomatal closure to prevent dehydration of the plant, and eventually decreasing the photosynthetic rate. The differential performance of the giant reed clones was ranked according to their tolerance to S and WS by using the Stress Susceptibility Index. 'Agrigento' was the most WS resistant clone and 'Martinensis' was the most S resistant. 'Martinensis' and 'Piccoplant' were found to be the most suitable clones for growing under both stress conditions. Moreover, 'Fondachello', 'Cefalú' and 'Licata' were the most resistant clones to increasing S levels.Keywords: Arundo donax L.; biomass; water stress; salinity stress; photosynthesis; Stress Susceptibility Index.

“…The total reclamation time may be reduced 4-fold if an average biomass production of 40 Mg ha -1 DW was considered. This yield level is commonly obtained with giant reed in Italy from the 2 nd -3 rd cropping year (Angelini et al, 2005(Angelini et al, , 2009Cosentino et al, 2006) and it could be easily obtained also on our site due to the low Cd pollution level and high soil fertility. Obviously, there could be a significant reduction in reclamation time if total uptake is taken into account, considering that at the end of the reclamation period all the rhizomes also have to be removed from the soil.…”

Assisted phytoextraction of heavy metals: compost and Trichoderma effects on giant reed (Arundo donax L.) uptake and soil N-cycle microflora

Little information is available as to the real effectiveness of the phytoextraction remediation technique, since laboratory experiments are still the most common way in which this is measured. Given this, an experiment on a cadmium-polluted soil was carried out in open field conditions in Southern Italy with the aim of assessing the growth and the phytoextraction potential of giant reed (Arundo donax L). Compost fertilisation and Trichoderma harzianum A6 inoculations were used to verify the possibility of increasing the metal uptake of the crop. Biomass yield of giant reed in the first growth season (average 12.8 Mg ha -1 ) was not affected by the Cd concentration in the soil and this increased significantly with compost fertilisation (13.8 Mg ha -1 ). Both compost fertilisation and T. harzianum inoculation increased cadmium uptake and translocation in leaves. Nitrifying bacteria was shown to be a useful tool to biomonitor soil quality. These results proved the suitability of the giant reed for assisted-phytoremedation with the use of compost fertilisation and T. harzianum. IntroductionThe extent of soil pollution by potentially toxic elements (PTE) in industrialised areas is well documented (Glass, 1998;Black, 1999) and represents an important environmental concern due to their potential accumulation in the food chain. Human activities such as industrial plants, mining, road transport and the unwise application of sewage sludges, fertilisers and pesticides to agricultural soils are recognised to be the main sources of PTE pollution (do Nascimento et al., 2006;Lado et al., 2008). A large number of methods are available to remediate soils, such as soil washing with synthetic surfactants. However, these are extremely expensive, such that a large number of sites remain contaminated (Ensley, 2000). Moreover, ex situ soil reclamation techniques lead to a big reduction in soil fertility due to the soil disturbance and to the toxicity of synthetic surfactants. Soil washing with humic substances extracted from composted organic matter or from geochemical deposits represents a reliable alternative (Conte et al., 2005) and phytoextraction is a valuable complementary technique. It is low cost and environmentally safe (Wu et al., 2006) and is able to both remove heavy metal pollutants from the soil and to offer important economic and agronomic advantages (Mattina et al., 2003). It involves the utilisation of plants to remove heavy metals from soil and concentrate them in the biomass. For years now, metal hyperaccumulating plants such as Alyssum murale, Berkheya coddii, Brassica juncea and Thlaspi caerulescens have been considered the most suitable tool to decontaminate metal-polluted soils, but the low biomass growth and scarce ability to accumulate various different metals together (Krämer, 2005) have discouraged their inclusion in commercial phytoextraction protocols (do Nascimento et al., 2006). Consequently, the current trend is to use fast-growing high biomass crops that accumulate moderate levels of metals in ...
