Seed vigor is a complex physiological trait required to ensure the rapid and uniform emergence of plants in the field under different environmental conditions. Therefore, salicylic acid (SA, 0.5 mM) and calcium (Ca 2+ , 50 mM) priming were used as exogenous growth enhancers to stimulate wheat (Triticum durum Desf. cv. Yelken) seed vigor under high salinity. The main aim was to address whether priming of wheat with SA, Ca 2+ and SA+Ca (SA, 0.5 mM + Ca 2+ , 50 mM; their combination) could bring about supplementary agronomic benefits particularly under stressful environments such as salinity. Exogenous application of SA or Ca 2+ alone improved plant behavior in the presence of salinity stress. Nevertheless, the best results in terms of growth, seed vigor and total phenolic -flavonoids, chlorophyll -carotenoids contents and phenylalanine ammonia-lyase (PAL), ascorbic acide oxidase (AAO) activities and lipid peroxidation levels (LPO) were obtained in response to the combined SA+Ca treatment.

“…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).…”

“…SA pretreatment alleviates Cd toxicity in barley (Metwally et al, 2003) and maize plants (Krantev et al, 2008). It has recently been found that SA treatment caused both ABA and proline accumulation in wheat and increased resistance to salinity (Shakirova et al, 2003). SA ameliorates the damaging effects of heavy metals, such as lead and mercury (Mishra and Choudhuri, 1999).…”

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.

“…Azooz (2009) positively correlated the increased water contents with ameliorative and growth promoting effects of phenolics. Increase in seedling growth due to exogenous SA was correlated with enhanced cell division within apical meristems (Shakirova et al 2003). Higher concentration of FA (1000 ppm) inhibited seedling growth which was reflected by decrease in shoot length and biomass of roots and shoots (Table 1).…”

The present study reports the effects of pre-treatment with ferulic acid (FA) on antioxidant response of wheat seedlings. In comparison to hydropriming, 100 and 150 ppm of FA significantly enhanced seedling growth of wheat at 6th day after germination (DAG). However, 1000 ppm of FA led to reduction in seedling growth. Roots and shoots of wheat seedlings pre-treated with 100 ppm of FA showed significant upregulation of peroxidase (POX), ascorbate peroxidase (APX) activities. Although catalase (CAT) remained unaffected in the roots, but showed about 2-fold increase in the shoots. Despite of low glutathione reductase (GR) and high polyphenol oxidase (PPO) activities in the shoots and roots, respectively, ascorbic acid and total phenolic contents also increased at 6th DAG which may be due to the activation of their biosynthetic pathways in seedlings pre-treated with 100 ppm of FA. Proline content of wheat seedlings pre-treated with 100 ppm of FA remained unaffected. Results signify the role of FA pre-treatment in augmenting the antioxidant response of wheat and thereby suggest that at lower concentrations, it can be used for improving performance of wheat under various environmental constraints.
