“…Besides, some toxic metabolites can be degraded to the inorganic sulfate in the medium of moderately high sulfate ion concentration (50-100 mM Na 2 SO 4 ) (Shevyakova 1981). In the current study, plant growth responded differently to NaCl and Na 2 SO 4 stress (Table 1), which appeared to be species specific as observed in previous studies (Franklin et al 2002;Colla et al 2012;Devinar et al 2013). It was found that Clposed a greater interfering effect on plant development and water balance than SO 4 2- (Rogers et al 1998).…”

“…With salinity level at the same equimolar concentration, sulfate is less toxic to jack pine (Franklin et al 2002), pea (Hamdia and Shaddad 1996) and lucerne (Medicago sativa L.) (Rogers et al 1998). On the contrary, growth of Cornus stolonifera Michx (Renault et al 2001), Ocimum basilicum (Tarchoune et al 2010) and Prosopis strombulifera (Devinar et al 2013) decreased strongly in plants treated with Na 2 SO 4 than in plants treated with NaCl of the same molar concentration.…”

Salinity is a major factor negatively affecting plant growth and agricultural productivity. To gain a better insight into Basella alba responses to different salt stress, some physiological parameters were investigated on this species after 15-day exposure to 200 mM NaCl or 100 mM Na 2 SO 4 stress. Plant growth was significantly suppressed under salinity and a more pronounced impairment induced by NaCl instead of Na 2 SO 4 was observed. A high level of water content was maintained in salt-treated shoot. Salinity stress caused marked increase in Na ? , Ca 2? , Cl -and SO 4 2-concentrations and decrease in K ? level and K ? /Na ? , Ca 2? / Na ? and Mg 2? /Na ? ratios in plants. The absorptive abilities of K ? , Ca 2? and Mg 2? in plants were improved significantly under salinity. Plants suffered a deeper oxidative stress in the presence of NaCl than Na 2 SO 4 as evidenced by the higher increase in foliar superoxide anions (O 2 Á-) and malondialdehyde (MDA) production as well as electrolyte leakage. No salt-induced alterations were observed on foliar hydrogen peroxide (H 2 O 2 ) level. B. alba responded to the oxidative stress by enhancing antioxidant capacity involving ascorbate, reduced glutathione as well as antioxidant enzymes. Superoxide dismutase (SOD), ascorbate peroxidase (APX) and glutathione reductase (GR) were all involved in the detoxification of reactive oxygen species (ROS) in plants exposed to salt stress, whereas catalase (CAT) only functioned in the Na 2 SO 4 -treated plants. The ability of water maintenance in shoot and improvement of cation absorbability as well as enhanced foliar antioxidant capability all contribute to the salt adaptation of B. alba, whereas a more efficient cation transport system and antioxidant mechanisms may be responsible for the better acclimation of this species to Na 2 SO 4 than NaCl.

“…These plant hormones are considered as the most vital elements that are critical in controlling physiological responses in plant under salt stress environment (Khan and Khan 2013). ABA ABA is considered as the stress hormone because it effect internal signaling of plant against adverse environment, and plays a vital role throughout the plant life cycle and facilitates plant reactions to different abiotic and biotic stresses (Keskin et al 2010;Devinar et al 2013). ABA biosynthesis increased in rice under osmotic stress due to salt accumulation (Kumar et al 2013).…”

Rice (Oryza sativa L.) is highly susceptible to the rhizosphere salinity than other cereals. High sensitivity has been observed, mainly at vegetative and reproductive stages in rice. It is the duty of plant physiologists to comprehend the growth, development, and physiological processes of rice plants under stress. This paper includes the overview of rice growth and developmental processes influenced by salt stress and the regulation pathways involved in these processes. It also includes the promising salt tolerance strategies, i.e., genetic modification techniques, agronomic practices to improve rice growth, yield, and role of phytohormones and their management, especially inhibition of ethylene biosynthesis by using inhibitors 1-methylcyclopropene (1-MCP). Rice cultivation may be a first choice for improvement of salt tolerance through plant growth regulators and improved cultivation techniques. This study will significantly improve the understanding toward low rice grain yield and poor rice resistance under salt stress and will also stream scientific knowledge for effective utilization of salt affected soils by using different regulating ways.

“…In fact, NaCltreated plants accumulated similar levels of Na+ than Na 2 SO 4 -treated plants in their leaves, but they succeeded in ion compartmentalization and osmoregulation with direct consequences on their growth; these plants showed the lowest levels of SA. This response suggests that SA production is not a protective hormonal signal like ABA but a signal of injury in P. strombulifera under these adverse conditions (Devinar et al, 2013).…”

In this study, the profile of plant phytohormones traditionally considered as plant growth promoters (GA 1 , GA 3 , GA 4 , IAA and Z) was determined in roots and leaves of the halophyte Prosopis strombulifera grown hydroponically in iso-osmotic solutions of NaCl, Na 2 SO 4 and their mixture. Hormonal levels were correlated with growth parameters and ABA levels. Different sodium salts in the medium differentially affected the synthesis of these compounds. NaCl treated plants showed the greatest accumulation of GA 4 and GA 1 and lower levels of their metabolites GA 8 and GA 34 both in root and leaves, in coincidence with the optimum growth observed at Ψo -1.9 Mpa this response was also observed at Ψo -2.6 MPa. IAA level was unaltered in these plants while Z content was higher in roots than in leaves. In contrast, both leaves and roots from Na 2 SO 4 treated plants showed lower GA 1 and GA 4 and increased GA 8 and GA 34 levels at high salinity. High levels of IAA were found in roots of these plants, but the ABA/IAA ratio increased with increasing salt concentrations in the culture medium. This pattern was also observed in the high ABA/GAs ratios. Z levels were very low in all salt treatments. The results of this study show that the halophytic growth under NaCl treatment is mainly regulated by GA 1 and GA 4 and low relative levels of ABA and IAA. The toxicity of sulfate alters this pattern reversing the ratio ABA/GAs and increasing the synthesis of IAA in conjunction with increased lateral root formation. In bisaline-treated plants intermediate values were observed in the levels of these phytohormones as compared to monosaline treatment.
