“…3). Those results in agreement with those of numerous studies in various plant species (Grieve and Fujiyama 1987;Subbarao et al 1990;Song and Fujiyama 1996a;Botella et al 1997;Navarro et al 2000).…”

“…Under salt stress Salinity induced K + deficiency which has been implicated in growth and yield reduction of various crops, spinach (Chow et al, 1990) and maize (Botella et al, 1997). The increment of Ca concentration in the leaves of Nebraska cultivar may be due to that most of Ca migrates to the shoot as an osmoregulation to resist salt determined effects on shoot cells.…”

A water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth parameters (leaves and root dry weights) and some of biochemical parameters (nutrients concentration, photosynthesis pigment, Carbonic Anhydrase Activity (CAA), antioxidant enzyme activity Peroxidase (POD) and lipid peroxidation). The reduction effect on Paulista cultivar was higher than Nebraska cultivar at 100 mM NaCl salinity stress. Meanwhile, POD activity was increased under salt stress conditions. Lipid Peroxidation (LP) under 100 mmoL NaCl salinity was significantly increased. The two cultivars showed an increase in MDA content with NaCl salinity stress, but the increase in sensitive cultivars Paulista was higher than that in salt-tolerant Nebraska cultivar. Application of (AsA) not only mitigated the inhibitory effect of salt stress in both kidney bean cultivars, but also in some cases induced a stimulatory effect greater than that estimated in the control plants on growth parameters which were accompanied by marked increases in nutrients concentration and photosynthetic system (pigments and carbonic anhydrase activity). Ascorbic Acid (AsA) has been shown to be an essential antioxidant; agent may act as a scavenger of ROS for mitigating the injury on bio-membranes under salt stress. Therefore, this study suggested that (AsA) application may induce an adaptive response in kidney bean through stimulation of the antioxidant enzymes activities, photosynthesis processes and lower lipid peroxidation, in Nebraska relative to Paulista may contribute to salt tolerance mechanism in Nebraska.

“…1b), offering an alternative, or additional, explanation of enhanced K + release under Na + exposure (Britto et al 2010;Coskun et al 2013). Combined, the above effects of impaired K + influx and enhanced efflux are expected to result in blockage of K + translocation to the shoot (Erdei and Kuiper 1979;Botella et al 1997;Kronzucker et al 2006;Munns and Tester 2008), with obvious consequences for downstream events such as photosynthesis and stomatal function.…”

Sodium as nutrient and toxicant

Background Sodium (Na + ) is one of the most intensely researched ions in plant biology and has attained a reputation for its toxic qualities. Following the principle of Theophrastus Bombastus von Hohenheim (Paracelsus), Na + is, however, beneficial to many species at lower levels of supply, and in some, such as certain C4 species, indeed essential. Scope Here, we review the ion's divergent roles as a nutrient and toxicant, focusing on growth responses, membrane transport, stomatal function, and paradigms of ion accumulation and sequestration. We examine connections between the nutritional and toxic roles throughout, and place special emphasis on the relationship of Na + to plant potassium (K + ) relations and homeostasis. Conclusions Our review investigates intriguing connections and disconnections between Na + nutrition and toxicity, and concludes that several leading paradigms in the field, such as on the roles of Na + influx and tissue accumulation or the cytosolic K + /Na + ratio in the development of toxicity, are currently insufficiently substantiated and require a new, critical approach.
