“…One of the possible solutions is development of crop cultivars tolerant to higher concentrations of salinity. The biological approach, to overcome the salinity problem, has received considerable attention in the last few decades (Weber et al, 2007). The deleterious effect of salinity on plant growth area associated with (i) low osmotic potential of the soil solution (water stress), (ii)…”

A pot culture was carried out with Oryza sativa L. vari-Co-39, to investigate the effects of supplementary calcium chloride on plants grown at NaCl (50mM) concentration. Treatments were: (1) Control: nutrient solution alone (C); (2) nutrient solution plus 50mM sodium chloride (NaCl); (3) nutrient solution plus 10mM calcium chloride (CaCl 2 ); (4) nutrient solution plus 15mM calcium chloride (CaCl 2 ); (5) nutrient solution and 50 mM NaCl plus supplementary 10 mM CaCl 2 (NaCl + CaCl 2 ); and (6) 50 mM NaCl plus additional mixture of 15 mM CaCl 2 in nutrient solution (NaCl + CaCl 2 ). The plants grown under salt stress produced low dry weight and relative water content than those grown in standard nutrient solution and in CaCl 2 alone. Supplemental calcium chloride added to nutrient solution containing salt significantly improved growth and relative water content. Membrane permeability increased with high NaCl application and these increases in root membrane permeability were decreased with supplementary Ca. The concentration of chloride (Cl) increases highly for all treatments. Sodium (Na) concentration in plant tissues increased in both shoots and roots at high NaCl treatment. Application of supplementary Ca lowered Na concentration. Concentrations of Ca. K and N were at deficient ranges in the plants grown at high NaCl levels and these deficiencies were corrected by supplementary Ca. The ameliorating effect of Ca on growth and physiological variables could reduce the negative effect of salinity of Oryza sativa L., plants.

“…It also has potential for production of oilseeds, forage, and biofuels (Glenn et al, 1991(Glenn et al, , 1999Weber et al, 2007;Christiansen, 2008). S. bigelovii is an out-crossing plant; however, seed setting with self-pollination is possible.…”

ABSTRACT. Salicornia spp is one of the most salt-tolerant vascular plants and is native to salt marshes and estuaries. We developed expressed sequence tag derived-simple sequence repeat (EST-SSR) markers for estimating genetic diversity and marker-assisted Salicornia breeding. Six polymorphic EST-SSRs of 40 detected 27 alleles, ranging from three to five alleles per locus. The average number of alleles per locus was 4.33 and 4.17, and the major allele frequency at locus DY529765 was high, being 0.859 and 0.857 in S. bigelovii and S. europea, respectively. Gene diversity, heterozygosity and polymorphism information content were highest at locus DY529950 and similar in EST-SSR-based molecular variance in two Salicornia populations these two species. Gene diversity increased with increase in the number of alleles that had a low major allele frequency at a locus. Six polymorphic loci effectively discriminated 46 taxa into three clusters via different analyses. Significant deviation of F ST from zero in three suggested populations for six loci indicated population differentiation and limited gene flow among them. A reduced median network established that taxon SB65 is primitive. SMART (simple modular architecture research tool) analysis of peptide sequences of six EST-SSRs showed that loci DY529765, DY529950 and EC906203 contained transmembrane, TLC, AgrB and NTR domains and might be involved in salinity stress tolerance. These EST-SSRs are a valuable resource for marker development and may be useful in marker-assisted Salicornia breeding.

“…There are, however, salt-tolerant plants, called halophytes that can grow and complete their life cycles in saline water. Halophyte species have been identified to produce a variety of useful products, including firewood or timber from mangroves for example [27]; fresh vegetables [28,29]; oilseeds [30][31][32]; grains [31]; medicine [33,34]; forages for livestock [35][36][37]; for phytoremediation [38,39]; biofuel [40][41][42][43]; as biofilters for saline aquaculture effluent [44,45] and ornamentals [46]. There have been efforts to grow some of these species in agricultural settings using seawater [30,31].…”

Sustainable Agriculture in the Arabian/Persian Gulf Region Utilizing Marginal Water Resources: Making the Best of a Bad Situation

One way to encourage agricultural self-sufficiency in arid regions is to increase the productivity of conventional freshwater agriculture. Another way is to develop and implement novel strategies and technologies that do not deplete scarce freshwater. Here we describe several options for countries in the Gulf region to increase their agricultural production by taking advantage of a lesser used resource-marginal water. Marginal water can be treated sewage effluent, produced oilfield water, brackish groundwater or seawater. We describe how this resource can be used to grow salt-tolerant forage crops, microalgae and aquaculture crops. Policies needed to implement and/or scale-up such practices are also outlined.
