“…Treatment with SA increased the pigment contents (Moussa and Khodary, 2003;Krantev et al, 2008). Pretreatment of plants with SA induced a considerable increase in 14 CO 2 assimilation, photosynthetic activity and chlorophyll content, as also reported by Khan et al (2003), Moussa and Khodary (2003) and Krantev et al (2006). The activities of both carboxylating enzymes (RuBPC and PEPC) exhibited a strong reduction at all the Cd concentrations applied (Moussa, 2004;Krantev et al, 2006).…”

“…The exogenous application of SA increased yield (Raskin, 1992). Further, SA retarded ethylene synthesis, affected membrane depolarization, stimulated the photosynthetic apparatus and protein synthesis, and increased the content of chlorophyll (Khan et al, 2003;Shakirova et al, 2003). Salicylic acid mediates some positive acclimation responses to abiotic stress factors, such as heavy metals, herbicides, low temperatures and salinity (Janda et al, 1999;Metwally et al, 2003).…”

Treatment with CdCl 2 (0, 100, 400 and 1000 µM) resulted in the inhibition of root dry biomass and root elongation and to increased Cd accumulation in the roots. These treatments also decreased the relative water content, chlorophyll content, 14 CO fixation, phosphoenol pyruvate carboxylase and ribulose-1,5-bisphosphate carboxylase activity and abscisic acid (ABA) content, while increasing the malondialdehyde, hydrogen peroxide and free proline contents and causing changes in the chloroplast and root ultrastructure. Pretreatment of seeds with SA (500 µM) for 20 h resulted in the amelioration of these effects.

“…The activities of enzyme CA in the plants receiving both NaCl (100 mM) and AsA were 6.7 and 22.30% higher than those receiving NaCl (100 mM) alone. Ascobicacid (AsA) plays a key role in the activation of rubisco and PEP carboxylase and CA under stress as documented by explain the (AsA) mediated elevation in the activity of CAA is that it corrects the stress mediated damage to the plasma membrane, as evident from an increase in the membrane stability (Khan et al, 2003).…”

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.

“…SA treatments increased the level of cell division by stimulating the mitotic system of the apical meristem of roots which caused better plant growth [13]. SA has important roles in flowers induction, nutrients uptake, ethylene biosynthesis [6], stomatal movement, photosynthesis and various physiological processes including plant growth [7]. The effects of SA have been well established in inducing salt tolerance in many field as well as vegetable crops such as bean [14], tomato [15].…”

“…Increasing plant tolerance against stress to improve productivity for our extra world population is now best implications in agriculture. Hayat et al [6] recognized salicylic acid (SA) as a plant hormone whose plays a vital physiological role on growth and development [7] and abiotic stress tolerance in plants.

Introduction: This experiment was set up to investigate the beneficial effect of salicylic acid to reduce the harmful consequence of salinity on cabbage productivity where Salt stress severely limits plant growth, development and yield. Methods: We had grown cabbage plants under different levels of NaCl salinity (0, 4, 8 dS m -1 ) alone or supplemented with foliar spray of different concentrations of salicylic acid (SA, 0, 0.25 and 0.5 mM). This experiment was laid out in a randomized complete block design with three replications. Collected all data were statistically analyzed following the analysis of variance (ANOVA) technique using MSTAT-C program and the mean differences were adjudged by least significant difference (LSD) test at 5% level of significance. Results: Results showed that, higher concentrated salt treated plants give the significant lower growth and head yield. Plant growth as well as yield of cabbage such as heads thickness, diameter and weight were decreased with increased level of salinity such as 8 dS m -1 compared with other treatment. While, foliar application of SA increased growth and yield also hindered stress induced growth and production inhibition. The improvement in plant height, leaf number, leaf length and breadth, foliage coverage, number of root and weight, head thickness, diameter and weight were increased with increased concentration of SA and higher value were recorded from 0.50 mM SA. Conclusions: It can be concluded that SA improve the plant defense system to resist the toxic effect of salinity.
