“…Risks associated in using highly saline water as a plant water source include poor seed germination, reduced seedling growth, and reduced plant vigor (Sairam and Tyagi , Paz et al. , Riccardi et al. , Sperling et al.…”

“…As groundwater in the region is high in salinities (2.58-29.70 g/L), plants grown in the TDHS are typically drip-irrigated with local saline groundwater (Xu et al 2006). Risks associated in using highly saline water as a plant water source include poor seed germination, reduced seedling growth, and reduced plant vigor (Sairam and Tyagi 2004, Paz et al 2012, Riccardi et al 2014, Sperling et al 2014, Zhao et al 2014.…”

Survival and growth of three afforestation species under high saline drip irrigation in the Taklimakan Desert, China

Afforestation of shelterbelts is a sustainable practice to protect highways from shifting sand dunes in desert areas. The Taklimakan Desert Highway Shelterbelt (TDHS) in China is known as “the Great Green Wall of Taklimakan Desert” and borders a 436‐km distance along the highway. This study assessed the early survival, above‐ground growth, and root growth of three salt‐ and drought‐tolerant plant species (Calligonum aborescens Litv., Tamarix ramosissima Ledeb., and Haloxylon ammodendron (C. A. Mey.) Bunge) in TDHS; those were drip‐irrigated with local high saline groundwater. The results demonstrated that more than 80% of Haloxylon ammodendron seedlings could survive regardless of irrigation water salinities ranging from 2.82 to 29.70 g/L. In contrast, survival rates of Calligonum aborescens seedlings were greater than 65% when using irrigation water salinities ≤13.99 g/L and less than 50% when irrigated with water having salinities of 20.99–29.70 g/L, respectively. However, plant survival rates of Tamarix ramosissima were much lower than 50% when irrigated with water having salinities >4.82 g/L. Furthermore, under the same salinity, the height, crown width, and maximum width of basal stems were the greatest for Calligonum aborescens plants and the lowest for Tamarix ramosissima plants. Root length varied among the species depending on tree age and the applied water characteristics. We conclude that afforestation is feasible with saline water in this extreme arid shifting desert, particularly Calligonum aborescens plants should be grown at the outer margin of the shelterbelt due to its faster growth to more quickly stabilize the shifting sand. Our study may provide a good resolution for afforestation and marginal saline water utility in most arid and semiarid regions.

“…This region is characterised by the presence of soil Na 2 CO 3 and NaHCO 3 (Costa & Garc ıa 1998), the main sources of high soil alkalinity (pH > 9.0). In a previous work, the response of L. tenuis plants to saline, alkaline and mixed saline-alkaline stresses were compared in relation to plant growth, key nutrient accumulation and root architecture and anatomy (Paz et al 2012). However, the morpho-anatomical responses of L. tenuis shoots to the above stresses remains unexplored.…”

Akaline, saline and mixed saline–alkaline stresses induce physiological and morpho‐anatomical changes in Lotus tenuis shoots

Saline, alkaline and mixed saline-alkaline conditions frequently co-occur in soil. In this work, we compared these plant stress sources on the legume Lotus tenuis, regarding their effects on shoot growth and leaf and stem anatomy. In addition, we aimed to gain insight on the plant physiological status of stressed plants. We performed pot experiments with four treatments: control without salt (pH = 5.8; EC = 1.2 dSÁm À1 ) and three stress conditions, saline (100 mM NaCl, pH = 5.8; EC = 11.0 dSÁm À1 ), alkaline (10 mM NaHCO 3 , pH = 8.0, EC = 1.9 dSÁm À1 ) and mixed salt-alkaline (10 mM NaHCO 3 + 100 mM NaCl, pH = 8.0, EC = 11.0 dSÁm À1

“…Evident differences in the morphology of the root system as a function of salt stress treatment were found in L. tenuis (Echeverria et al, 2008). Neutral and alkaline salts produced a similar detrimental effect on L. tenuis growth, whereas the effect of their combination was synergistic (Paz et al 2012). The pattern of morphological changes in L. tenuis root architecture after the alkaline treatment (in the absence of NaCl) was similar to that found in the mixed saltalkaline treatment and different from that observed in neutral salt.…”

“…Alkaline stress refers to the presence of alkaline salts (Na 2 CO 3 or NaHCO 3 ) in the soil, whereas saline stress is related only to neutral salts such as NaCl or Na 2 SO 4 .Although saline stress has been addressed in numerous studies, alkalinity rather than salinity is the main constraint for cropping activity (Paz et al 2012). Studies on abiotic stress in L. tenuis have been focused principally on NaCl tolerance (Sánchez et al 2005;Sannazzaro et al 2006Sannazzaro et al , 2007Echeverria et al 2008;Uchiya et al, 2016), whereas less studies has addressed its tolerance level to alkaline and mixed salt-alkaline stresses.…”

The Salado River Basin region is the most important livestock breeding area in Argentina, wherethe Lotus species has been traditionally cultivated as forages. Nearly 60% of their land surface is dominated by salt-affected soils with severe constraints for crop cultivation. In order to cope with that limitation, farmers have utilized species such as non-native L. tenuis (ex-Lotus glaber), which shows a very good adaptation. As a result, inter-seeding of L. tenuis has been proposed as a strategy of choice for improving forage production in marginal areas. The increase in soil quality by these means is achieved by an increment of the organic matter content, improvement of soil fertility as well as microbial biodiversity. Thus, the introduction of L. tenuis and/or other Lotus genotypes could have enormous benefits for similar constrained lands around the world. We are developing an integrated analysis of the changes that occur in soils under legume production. We will not only analyze the microbial diversity associated, but also soil physical and chemical characteristics and the impact of different legume-microbes association on mitigation of GHG emissions. In addition, we are identifying the main genetic determinants associated with interesting agronomic traits such as plant tolerance against biotic and abiotic stresses and the content of condensed tannins. Our future and present research will build a solid base for the improvement of agronomicallyimportant species and the development of better strategies for the management of constrained lands such as the lowlands in the Argentinean Pampas.
