“…1) and Ti (Exp. 2) were similar in the control treatments (WW S-and S0, respectively) across the giant reed clones even at different locations, with the A sat values similar to those reported by Papazoglou et al [39] and Nackley et al [27].…”

“…Giant reed is a C 3 perennial rhizomatous grass (PRG) belonging to the Poaceae family. It has been reported that giant reed has a high photosynthetic potential [26] and a relatively high transpiration rate, therefore it requires more water to produce the same biomass as many C 4 biomass crops [27,28]. Related to yield, the greater biomass productivity of giant reed is also achieved under low input conditions.…”

Salinity and Water Stress Effects on Biomass Production in Different Arundo donax L. Clones

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.

“…Indeed, the instantaneous WUE (A/E), averaged between the three growing seasons and measurement times, was 5.01 mol CO 2 /mmol H 2 O at FC and 5.32 mol CO 2 /mmol H 2 O at WP (data not shown). Stomata regulation and reduced transpiration have been reported as primary mechanisms for drought avoidance for several crops, including for M. sinensis and A. donax (Clifton-Brown and Lewandowski, 2000;Ings et al, 2013;Nackley et al, 2014). Similarly to A. donax, leaf rolling was detected in Saccharum thereby increasing avoidance of dehydration by reducing incident radiation on leaves, leaf temperatures, and water loss (Cosentino et al, 2014b).…”

“…These effects are currently not simulated by Arungro because extensive information about giant reed responses to different atmospheric CO 2 concentrations is still lacking. However, a recent exploratory study [46] demonstrated that giant reed grown under enriched CO 2 environments markedly reduced transpiration rates, in turn, increasing the water use efficiency and enhancing drought tolerance. Concerning nutrient availability, the simulation of unlimited conditions under the explored conditions is likely to provide reliable estimates for both current and future scenarios.…”
