“…The overall objective of this study was to assess whole plant and leaf-level physiological responses of Tamarix ramosissima to extreme NaCl concentrations. Previous results suggested that Tamarix ramosissima maintained physiological functioning in the field from 0 to 14 g•l -1 NaCl [47]. In this study, Tamarix ramosissima had decreased gas exchange, maximum quantum yield of photosystem II, and Ψ w at 15 and 40 g•l -1 NaCl, compared to the control.…”

Hydrologic alterations of river systems in western North America over the past century have increased soil salinity, contributing to the establishment and spread of an introduced halophytic species, Tamarix ramosissima (Ledeb.). The physiological responses of Tamarix ramosissima to salinity stress are incompletely known. To assess the salinity tolerance of this species, we measured several whole plant and leaf-level physiological responses of Tamarix ramosissima cuttings grown in a controlled environment over three NaCl concentrations (0, 15 and 40 g•l -1 ). Tamarix ramosissima photosynthesis (A 2000 ), stomatal conductance to water (g s ), water potential (Ψ w ), and the maximum quantum yield of photosystem II (F v /F m ) decreased at 15 and 40 g•l -1 NaCl compared to control treatments. However, after approximately 35 days, Tamarix ramosissima had increased photosynthetic rates, maximum quantum yield of photosystem II, and stomatal conductance to water. These data suggests that physiological functioning of Tamarix ramosissima acclimated to extremely high NaCl concentrations over a relatively short period of time. Additionally, we present preliminary evidence that suggests proline synthesis may be the mechanism by which this species adjusts osmotically to increasing salinity.

“…Similarly, our gas exchange data show reduced stomatal conductance at 40 g•l -1 NaCl. In controlled outdoor experiments Tamarix ramosissima maintains high leaf stomatal conductance when under water or salt stress [9,[46][47][48].…”

“…These nutrients are rare in cereals but essential to maintain a dietary balance and are also a source of income and traditional medicines [ 6 , 7 , 8 ]. However, abiotic stresses have caused a significant dysfunction in the bio-functioning of the ecosystems and in the long term, would no longer allow plant cover to ensure its sustainability and development [ 9 ].…”

“…In this relationship, only E, D, and R are difficult to measure. For the case of woody plant water functioning, E, D and R are negligible (Lufafa et al, 2008;Seghieri, 2010;Moiwo et al, 2011;Carter and Nippert, 2012). We freed ourselves from D by prospecting a 0-200 cm soil slice beyond which there is little or no variation in moisture.…”

Water deficit is considered by several authors to be the most limiting factor for agricultural production in the subtropics (Kizito et al., 2006; Porcel and Ruiz-Lozano, 2004; Bader et al., 2006; Logan et al., 2010; Rodriguez-Gamir et al., 2011; Conedera et al., 2011). On woody plants, only a few isolated studies (on Acacia, and combretaceae) exist in the tropical zone south of the Sahara. Noteworthy are the works done on Sahelian forest species, Acacia tortilis (Diouf, 1996), Combretum glutinosum, Guiera senegalensis; Piliostigma reticulatum; Balanites aegyptica, Boscia senegalensis, A. senegal and Ziziphus mauritiana (Fournier, 1995; Kizito et al., 2006; Lufafa et al., 2008). Characterization of plant water functioning is a tool for selecting plants and/or varieties for their tolerance to water deficit (Lufafa et al., 2008; Zhu Qiuan et al., 2011; Logan et al., 2010). It is most often done at young age for ease of use (nursery and early field establishment of seedlings). However, even as adults, woody plants remain dependent on climatic factors such as rainfall (Kisito et al., 2007; Lufafa et al., 2008). It is therefore important to understand the in situ water functioning of adult plants to better explain the depressive effects of such complex water stress at a young age. However, the behavior of plants in situ is influenced by the climatic conditions and the uniformity (age) of the subjects (tamarind plants) to be followed. The present work was carried out on adult T. indica plants in situ in Senegal (Niokhoul in the Sahelian zone and Mbassis in the Sudano-Sahelian zone) and aimed mainly to: (1) understand and describe the physiological water management strategies of tamarind under arid conditions; and (2) understand the impact of this water management strategy on phenology and productivity. The study was conducted in Senegal, characterized by a dry and arid climate. It adopted a field approach (Seghieri, 2010; Conedera et al., 2010) based on adult stands and climatic data collected at the study sites. Ultimately, the adaptation mechanism of tamarind to water deficit would be that of avoidance, described by various authors (Khalfaoui, 1985; Lacape, 1996; Nwalozie and Annerose, 1996; Rouhi et al., 2007; Roussel, 2008; Maes et al., 2009). Indeed, the plant first proceeds to a decrease in water potential (case of the Mbassis stand) and in case of continuous water deficit, it integrates the reduction of the leaf surface by the progressive fall of the leaves and flowers which can go up to the total defoliation (case of the stand of the Sahelian zone in Niokhoul).
