“…Therefore, we hypothesize that FF and also SA as a seed pre-treatment may be the best appropriate for food crops that are naturally rich in phenolic compounds. Plant phenolics could be utilized in agriculture as eco-friendly alternatives for weeds and pest management (Saleh and Madany 2015). From our results, maximum PAL activities and maximum phenolic content were observed in shoots grown from seeds primed 0.1 mM SA + FF combined pre-treatment.…”

“…Thereby, the significant accumulation of salicylic acid in the shoot of salt-stressed wheat, SA + FF combined pre-treatment seedlings can contribute to the growth ameliorative effect of SA and FF. Application of 100 mM NaCl increased the level of ferulic, cholorogenic, salicylic acids, decreased syringic, vanillic, gallic and trans-cinnamic acids in previous studies (Saleh and Madany 2015). In our study, it is determined that SA + FFcombined pre-treatment resulted an increase (p < 0.05) in all the detected free phenolic compounds and this result could bring out a direct or indirect role of SA + FF-combined pre-treatment in regulation of shikimic acid biosynthetic pathway.…”

“…This statement may be supported by the threefold increases of scopoletin, approximately twofold increases of phenolic acids in the shoot of SA + FFprimed wheat under non-salinity conditions. Scopoletin and caffeic and vanillic acids has been determined as the major phenolic compounds in wheat by the other researches (Saleh and Madany 2015).…”

The potential effect of combined salicylic acid and fish flour to improve plant tolerance to salt stress was investigated. This pre-treatment improved the growth of wheat seedlings under salinity when compared to control (untreated wheat seedlings). Moreover, combined pre-treatment improved significantly phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzyme activities, also phenolic-flavonoid content in the shoots of salt stressed seedlings. One of the most important consequences of increase in salt stress is the oxidative tissue damage. In our study, salt stress increased lipid peroxidation levels (LPO) and also the loss of chlorophylls levels during stress might also be related to photo-oxidation resulting from oxidative stress. Whereas phenylalanine ammonia-lyase (PAL) activities of wheat shoots increased by a 2.1-fold under salt stress, the activities of shoots grown from seeds primed with salicylic acid and fish flour (SA + FF) increased by a 4-fold for 0.05 mM SA + FF, 4.8-fold for 0.1 mM SA + FF and 3.7-fold for 2.5 mM SA + FF combined pre-treatment under salt stress. Also, the combined salicylic acid + fish flour primed seedlings showed higher content of the scopoletin, and salicylic, syringic, vanilic and gallic acids under both salt and nonsalinity stress conditions.

“…Therefore, our research shows that saline stress induced during the growth of sunflower plants immediately after germination, causes the accumulation of proline in the plumules in response to the stress factor. In this context, other studies have also shown that the accumulation of free proline in saline stress conditions is an osmotic control reaction of sunflower plants (Lehmann et al, 2010;Khalil, 2017, Reddy et al, 2004;Saleh and Madany, 2015).…”

The purpose of the experiment was to highlight the germination of sunflower seeds affected by the presence of saline stress and the identification of tolerant genotypes. The biological material was represented by sunflower cvs. (Helianthus annuus L.): Coril, Select, Santiago and Fundulea-206. To simulate the saline conditions, germination solutions of sodium chloride (NaCl) were used with concentrations corresponding to the osmotic pressures -6 and -10 atm and the control seed hydration was performed with distilled water. Determination of seed germination, growth of seedling, percentage of plumules dry matter, chlorophyll content and free proline were performed. The experimental data obtained suppose the existence in the assimilation apparatus of sunflowers seedling subjected to stress a competitive chlorophyll/free proline biosynthesis processes. The experimental results regarding the effect of salinity on seed germination and seedling growth revealed important differences between genotypes. The radicle growth in the germination process were strongly affected by saline excess, with significant differences between cultivars. Saline stress results in significant reductions in the amount of chlorophyll, and high levels of free proline. It can be observed that with the increase of the stress level the percentage of the dry matter increases, indicating an accentuated water deficit.

“…In the present study, the decrease in TPC could be ascribed to decreased activity of phenylalanine ammonia lyase (PAL: the first enzyme of the phenylpropanoid pathway that catalyzes the elimination of NH 3 from L-phenylalanine to produce trans-cinnamate) probably due to the accumulation of toxic levels of Na + and Cl -. Supporting information is provided by [45], who reported that decreased phenol accumulation was associated with lower PAL activity in wheat. The susceptibility of the phenylpropanoid metabolism to salinity justifies our previous conclusion about the sensitivity of M. vulgare to salt stress.…”
