“…The most common and significant effect of salt and drought stresses on plants is the inhibition of growth and biomass production (Kavas et al 2015). Our results showed that SD1 and SD2 decreased G. uralensis growth and biomass compared with control, and this adverse effect was partly reversed by Si addition (Table 2 and 3), which is consistent with previous findings in sugarcane (Ashraf et al 2010), G. uralensis seedlings (Zhang et al 2017), and canola (Hashemi et al 2010).…”

Silicon has been widely reported to have a beneficial effect on improving plant tolerance to biotic and abiotic stresses. However, the mechanisms of Si in mediating responses to simultaneous salt and drought stresses are still poorly understood. Glycyrrhiza uralensis Fisch. is classified as a non-Si accumulator and suffered from salt and drought stresses. In this study, we investigated the long-term application of Si on Si content in G. uralensis roots, stems and leaves, leaf anatomy, ultrastructure, chlorophyll (Chl) content, gas exchange characteristics, relative water content, and growth of two-year-old plants under different salt and drought stresses. Silicon application resulted in a higher Si uptake in G. uralensis roots and more Si accumulation in leaves (especially deposition of Si on cell walls), and Si counteracted the adverse effects induced by salt and drought stresses on the leaf anatomy and ultrastructure. In plants treated with Si, a higher chlorophyll content, net photosynthetic rate and relative water content led to a higher growth rate and dry mass under salt and drought stresses compared with corresponding non-Si treated plants.Additional key words: chlorophyll, leaf ultrastructure, net photosynthetic rate, relative water content, stomatal conductance, transpiration rate, water use efficiency.

“…However, to date little is known about the effect of abiotic stress on phytochemical accumulation in edible sprouts and the application of environmental stress to enhance their quality traits as well as the actual translatability of the enriched-bioactive compounds to biological benefits in lifestyle-related diseases. The effect of salt stress on bioactive compounds accumulation was studied in sprouts of radish (Yuan et al, 2010), broccoli (Guo et al, 2014), lentil (Świeca, 2015), peanut (Kavas et al, 2015), alfalfa ) and buckwheat (Lim et al, 2012). In wheat (Triticum aestivum L.) the impact of salt stress was only evaluated in terms of germination rates and biometric determinations (Datta et al, 2009) while no quality trait was assessed.…”

Effects of sprouting and salt stress on polyphenol composition and antiradical activity of einkorn, emmer and durum wheat

Germination is related with improvements of nutritional value of seeds, since it promotes accumulation of health-promoting phytochemicals. However, only few studies have investigated on phytochemicals accumulation during sprouting under sub-optimal conditions. Thus, we investigated the effect of salinity during germination of an einkorn (TMoM), an emmer (TDiZ) and a durum wheat (TDuC) genotype on the total polyphenols (TPC), free-and bound-phenolic acids [PAs; i.e. caffeic acid, syringic acid, Pcoumaric acid, trans-ferulic acid, and salicylic acid] contents and antiradical activity (Trolox equivalent antioxidant capacity; TEAC) of sprouts and wheatgrass. The following NaCl treatments were applied: 0 (control), 25, 50 and 100 mM NaCl concentration throughout the whole experiment, or 50 and 100 mM NaCl until sprout stage and then 0 mM until wheatgrass stage (recovery treatments). TMoM showed higher total bound-PAs both in sprouts and wheatgrass with respect to the other Triticum genotypes (+25% and 24%, respectively) as well as of total bound-PAs and bound-SA in the recovery treatments. Moderate salt stress significantly increased all the investigated variables in TDiZ. Salt stress induced higher TPC and TEAC as well as total free-PAs values till 50 mM NaCl in TDuC, whilst significantly lowered total boundPAs due to the negative variation of both P-CA (-84%) and trans-FA (-81%) acids. Results indicate that salinity during germination could be efficiently modulated to improve the nutritional quality of sprouts, wheatgrass and cereal-based products.

“…Carrasco-Rios and Pinto (2014) 33 grew the maize plants in 50 and 100mM NaCl stress and reported decreased catalase activity in plant shoots at 100mM NaCl stress. Kavas et al (2015) 13 treated two 12-day old peanut cultivars with 0/100/ 300mM NaCl for 16 days and found decreased catalase activity in both. Naik et al (2016) 16 treated 10-day old niger plants with 0-500mM NaCl for 24/48/72 hours and reported reduction in catalase activity.…”

“…However, majority of reports are of increase. Salt stimulated GR increase has also been reported in a number of plants like Gossypium hirsutam (0-150mM NaCl for 30 days) 34 , Phaseolus vulgaris (5-day old plants with 400mM NaCl for 48 hours) 35 , Atriplex hortensis (260mM NaCl for 3 months) 32 , Zea mays (21 day old two maize varieties in 0/50mM/100mM NaCl for 15 days) 35 , Arachis hypogea (two 12-day old peanut cultivars with 0/100/ 300mM NaCl for 16 days) 13 , chickpea (0-200 mg L −1 NaCl) 15 , Brassica juncea (250mM NaCl stress for 6 hours) 17 and Guizotia abyssinica (0-500mM NaCl for 24/48/72 hours) 16 .…”

The antioxidant enzymes system in the shoot of the Zea mays was checked in the laboratory. The seeds Soil culture of Zea mays (cv. African Tall-09) were purchased from the local market and sterilized properly. The growth was done for five days and treated by two NaCl (100mM and 200mM) levels, two kinetin (2µM and 5µM) levels and their respective combinations. The enzymatic assays of key antioxidant enzymes i.e. catalase, guaiacol peroxidase (GPX), ascorbate peroxidase, superoxide dismutase and glutathione reductase (GR) in maize leaves were done. The assessment of important metabolic parameters i.e. lipid peroxidation, non-protein thiol levels and proline content in maize leaves was also performed. The activity of catalase was very strongly responsive for kinetin and increased its activity at both the levels. The activity of GR was also inhibited in case of salt and kinetin grouping of lower concentration level. The GPX activity was inhibited by 100 and 200mM of NaCl levels in external medium but stimulated by 5µM Kinetin level alone as well as in high amount salt combination levels while superoxide dismutase of Zea mays shoots was stimulated and showed noteworthy gain were shown in response to 200mM NaCl level as well as kinetin levels. The lower combina tion of both salt and kinetin suppressed the activity of ascorbate peroxidise while the lipid peroxidation and proline content were increased by both the salt treatments.
