“…At the end of the study period, P. australis showed a higher above-ground/below-ground ratio (2.7) than A. donax (1.5; Table 2). The reported high above-ground production confirms the high productive potential of the two species cultivated under optimal water and nutritional conditions (Idris et al, 2012a;Borin et al, 2013b).…”

C3 plant species are widely used to vegetate constructed wetlands (CW), but so far no information is available on their effect on CW CO2(eq) balance in the Mediterranean climate. The aim of this research was to study carbon dioxide (CO2) and methane (CH4) emissions and CO2(eq) budgets of CW horizontal sub-surface flow pilot-plant beds vegetated with Arundo donax L. and Phragmites australis (Cav.) Trin. ex Steud. compared with an unvegetated bed in Sicily. The highest total plant biomass production was measured in the bed vegetated with A. donax (17.0 kg m -2 ), whereas P. australis produced 7.6 kg m -2 . CO2 and CH4 emissions and showed significant correlation with average air temperature and solar radiation for each bed. The CO2 emission values ranged from 0.8±0.1 g m -2 d -1 , for the unvegetated bed in April, to 24.9±0.6 g m -2 d -1 for the bed with P. australis in August. The average CO2 emissions of the whole monitored period were 15.5±7.2, 15.1±7.1 and 3.6±2.4 g m -2 d -1 for A. donax, P. australis and unvegetated beds respectively. The CH4 fluxes differed significantly over the monitored seasons, with the highest median value being measured during spring (0.963 g m -2 d -1 ). No statistical differences were found for CH4 flux among the studied beds. Cumulative estimated CH4 emissions during the study period (from April to December) were 159.5, 134.1 and 114.7 g m -2 for A. donax, P. australis and unvegetated beds respectively. CO2(eq) balance showed that the two vegetated beds act as CO2(eq) sinks, while the unvegetated bed, as expected, acts as a CO2(eq) source. Considering only the above-ground plant biomass in the CO2(eq) budgets, P. australis and A. donax determined uptakes of 1.30 and 8.35 kg CO2(eq) m -2 respectively.

“…It is classified as an emergent aquatic plant (Cook, 1990). Like P. australis, it is a C3 species, with an unusually high photosynthetic capacity (Rossa et al, 1998) and productivity similar to that of C4 species (Christou et al, 2001;Borin et al, 2013b).…”

The different water and irrigation methods have been selected with respect to the main availability and practice of the different units [18]. Each RU planted one of the four species in its own larger plot (ranging from 60 to 480 m 2 ) and the other ones in the smaller plots (ranging from 9 to 60 m 2 ) with three repetitions.…”

“…Arundo donax (giant reed) is a perennial plant that grows in Mediterranean climates with high biomass production and potential for pulp, chemicals and energy [138]. The lignin content in the whole stalk is 21.1% [139] with 16-22% in the internodes and 15-20% in nodes [140].…”

The objective of this chapter is to provide a concise overview of lignin composition and structure in different species and materials (wood, barks and nonwood plants). It includes a brief review on the lignin precursors and their polymerization as well as of the analytical tools used for lignin characterization from wet chemical to spectroscopic methods. Wood of gymnosperms is characterized by high lignin content (25-35%) and a HG-type of lignin with more guaiacyl (G) units and a small portion of p-hydroxyphenyl (H) units. Wood of angiosperms has a lignin content of 15-28%, with a GS-lignin having different proportions of syringyl (S) units. Nonwoody monocotyledon species have different lignin content (9-20%) and a HGS type of lignin, characterized by a high proportion of H units. Bark lignin content ranges from 13 to 43% and is of HGS-type with species-specific composition and different in the bark components, phloem and cork. Lignin composition and macromolecular structure are key issues to understand the properties of lignocellulosic materials and to design a lignin-based pathway within biomass biorefineries. The available information on lignin composition is still limited to a few species and plant components. This is certainly an area where more research is needed.
