“…More or fewer data were reported by Abbas et al (2015) that foliar application of silicon (150 mgL −1 ), decreased lipid peroxidation and increased antioxidant enzymes activities in both leaves and root of okra under salt stress.Similar studies showed that siliconmediated enhancement in antioxidant enzyme activities and decreased in oxidative stress in saltstressed tomato plants grown in sand culture (Li et al, 2015). Figure 3 and Fig.4 indicated that salinity stress caused highly significant increases in all the assessed organic compounds (total soluble sugars proteins, amino acids and proline content).…”

T HE PRESENT study was carried out to investigate the effect of high NaCl concentrations on some growth parameters and physiological processes of wheat (Triticum aestivum L.) plant. The results indicated that Gemeza.9 was the most sensitive cultivar to high salinity levels compared to all tested wheat cultivars. Moreover, salinity stress caused a reduction in the germination percentage by 65% and all growth parameters by 21%, 25% and 60% in the lengths of shoot, root and leaf area, also by 27% and 48% in fresh weights of shoot, root and 40% and 75% in dry weights of shoot and root. It also increased the activity of antioxidant enzymes (peroxidase and catalase), lipid peroxidation and ascorbic acid content. Salinity induced increase of osmolytes compounds such as total soluble proteins, carbohydrates and amino acids. Furthermore, all measured yield parameters, the percentage of grain's maturity and productivity were highly decreased. Accordingly, the role of potassium humate and potassium silicate either sole or combined in alleviating the toxic effect of salinity was also studied. Results showed that application of potassium humate as sole had a stimulatory effect higher than potassium silicate or their combination. It increased the germinating percentage by 128% at 200mM NaCl. In addition, potassium humate and potassium silicate increased the photosynthetic activity, decreased the activity antioxidant enzymes (Peroxidase and Catalase) as well as biosynthesis of MDA and ascorbic acid also they induced increase biosynthesis of proteins and carbohydrates in yielded grains. Accordingly, our study recommends the application of potassium humate as an organic fertilizer and potassium silicate as a foliar spray for improving the quality and quantity of the sensitive wheat cultivar Gemeza.9 cultivated in salty lands and increases its productivity.

“…Salinity stress seriously declines crop productivity by way of osmotic stress, ion toxicity and oxidative stress. In the current study, salt stress noticeably decreased the growth attributes of cowpea plants such as shoot length, shoot and root dry weights and leaf area, which is in agreement with some previous reports on many crops (Kausar et al, 2013;Li et al, 2015;Abd-Allah et al, 2015;Dhanyalakshmi et al, 2013). Nonetheless, pre-treating seeds with MeJA enhanced the growth of cowpea under saline conditions.…”

Reduction in RWC under salt stress in the present study is in concurrence with the results of Abeer et al (2015) on cowpea, Gulmezoglu et al (2016) on green bean, Wang et al (2015) on cucumber, Li et al (2015) on tomato, and AbdAllah et al (2015) on common bean.

“…1). The reduction in photosynthetic pigments level due to salt stress has been reported in plants species Li et al, 2015). Decline in leaf chlorophyll content under NaCl stress has been attributed to preventing pigment and biosynthesis of proteins, destruction of pigment protein complex and increased activity of chlorophyllase enzyme Abd-Allah et al, 2015).…”

“…Adverse effects of salt stress are ascribed to osmotic stress, ion toxicity and production of ROS (Singh et al, 2015;Gupta and Huang, 2014). These effects cause various physiological, biochemical and agronomic changes, such as oxidative stress (Kausar et al, 2013;Sadak and Abdelhamid, 2015), internal nutrient imbalance Tartoura et al, 2014), alteration water status (Wang et al, 2015;Li et al, 2015), reduction pigments content, gas exchange and photosynthesis (Aftab et al, 2011;Wang et al, 2015), inhibition in seed germination (Nasri et al, 2016;Kusvuran, 2015) and reduction of growth and loss in productivity (Tartoura et al, 2014;Kausar et al, 2013). In order to cope up with salt stress plants undergo various biochemical and physiological changes, including: biosynthesis of compatible solutes and osmoprotectants, ions homeostasis and compartmentalization, control of ion uptake and transport, selective accumulation or exclusion of ions, generation of nitric oxide, changing hormone levels and enhancing antioxidative systems (Gupta and Huang, 2014).…”

Amelioration of salinity tolerance in cowpea plants by seed treatment with methyl jasmonate

A pot experiment was conducted to investigate the role of methyl jasmonate (MeJA) in alleviation of the adverse effects of salinity on cowpea. Seeds were soaked in 0, 25 and 50 µM MeJA for 20 h and then the seedlings were irrigated with different concentrations of NaCl (0, 50 and 100 mM). Salt stress markedly decreased growth attributes namely shoot length, shoot and root dry weight and leaf area. NaCl stress also significantly reduced chlorophyll value, stomatal conductance, net photosynthetic rate, total soluble proteins and relative water content (RWC). Furthermore, salinity noticeably increased proline and total soluble sugars content. Nonetheless, seeds treatment with MeJA especially 50 µM, improved the growth of cowpea plants by increasing chlorophyll value, stomatal conductance, net photosynthetic rate, total soluble proteins, proline accumulation, total soluble sugars and RWC under salt stress conditions. Thus results indicate that pretreatment of seeds with MeJA could be used as an effective technique for improving cowpea plants tolerance to salt stress.
