“…On the contrary, Hernandez et al () suggested that Ca addition decreased CAT and APX activities and that the higher salt tolerance observed after Ca addition was due to the protection it exerted on the plasma membrane. In the present study, the activities of CAT and APX increased after Ca addition supporting Al‐Whaibi et al () results and suggesting that Ca addition might directly enhance enzyme activities and decrease oxidative stress and growth inhibition.…”

“…Both CAT and APX activities increased with Ca application. Al‐Whaibi, Siddiqui, and Basalah () reported that Ca application to the solution improved plant growth and enhanced the activities of antioxidant enzymes in Triticum aestivum L. under salt stress. On the contrary, Hernandez et al () suggested that Ca addition decreased CAT and APX activities and that the higher salt tolerance observed after Ca addition was due to the protection it exerted on the plasma membrane.…”

Zoysiagrass (Zoysia japonica Steud.), a native grass in Japan, is a warm‐season turfgrass displaying high salt tolerance, mainly derived from salt excretion through salt glands. The present study focused on how external calcium (Ca) affects sodium (Na) excretion from salt glands to relieve salt stress, including response to oxidative stress, and discussed the physiological mechanisms possibly involved. Treatments using 0, 25, 50, 75, 100, 125 and 150 mmol/L sodium chloride (NaCl), with or without applying 2 or 10 mmol/L calcium chloride (CaCl2), were conducted for seven days. Growth inhibition and an abrupt increase in Na excretion from salt glands occurred above 100 mmol/L NaCl treatment, while Na concentrations in shoot and root tissues increased with increasing NaCl concentration from 0 to 75 mmol/L treatment. Above 100 mmol/L NaCl treatment, pectic acid‐binding Ca and glycinebetaine concentrations decreased in shoot and root tissues, but free proline concentration and the activities of plasmalemma ATPase, catalase (CAT) and ascorbate peroxidase (APX) increased. Calcium application alleviated growth inhibition when added to high level of NaCl treatments (over 100 mmol/L NaCl). Compared to the treatment without Ca, Na concentration in shoot and root tissues and ATPase activity in the root decreased, but Na exclusion from salt glands, pectic acid‐binding Ca concentration in shoot and root tissues, and ATPase, CAT and APX activities in the shoot increased. Thus, Na excretion through salt glands seems to occur when Na concentration in the plant exceeds its accumulation limit, and this salt tolerance reaction involving salt glands proceeds in two steps: the grass absorbs and accumulates Na in the shoot and root up to a threshold, above which Na is removed through salt glands. Calcium application promoted Na excretion through salt glands, especially under growth‐inhibiting Na concentrations, which might be induced by the increase in extracellular excretion of Na by plasmalemma ATPase.

“…SA or Ca alone as well as in combination significantly improved proline concentration. 14 The present study investigated whether exogenous SA and Ca 2+ could improve the seed germination of wheat via increasing phenolic contents under salinity stress. A range of plant physiological reactions to SA application are known, but more extensive studies focusing on the effects of SA on phenolic contents under high salinity are still lacking.…”

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.

“…Consequently, there is an increase in the cytosolic concentrations of Ca 2þ . Interestingly, simultaneous addition of SA and Ca 2þ reduces the NaCl-induced oxidative stress in wheat more effectively by preventing the accumulation of malondialdehyde (MDA) (Al-Whaibi et al, 2012). Raz and Fluhr (1992) reported that in the presence of an exogenous Ca 2þ , SA could induce chitinase formation in tobacco leaves that lack CaM.…”
