“…In this experiment, growth parameters were inhibited under NaCl concentrations. Reduction of plant growth under salinity have been previously reported by other researchers [6,10,28]. Exogenous application of PEN prevented, to some extent, the negative effects of stress, especially in 200mM NaCl treated plants, and allowed increased plant growth (Table 1).…”

“…However, its productivity decreases as the salinity level increases [5]. Under saline conditions, plants have adopted mechanisms to protect themselves by some strategies such as the accumulation of compatible solutes, the production of reactive oxygen species, and accumulation of important secondary metabolites [6]. The accumulation of compatible solutes such as proline and carbohydrate, which is in cytosole, is considered as a basic strategy for the protection of plants in response to stress conditions [7,8].…”

Salinization of soil is recognized as one of the most pressing environmental challenges to resolve for the next century. The ability to respond to environmental stimuli is among the most fundamental processes that enable plants to survive. Penconazole (PEN), a triazole group of fungicide, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses. The purpose of this work is to assess the effect of sodium chloride (0, 50, 100, and 200mM) and PEN (15mg/L) on some biochemical responses of sesame. Results revealed that some growth parameters decreased under salinity however, compatible solutes, H 2 O 2 and Malondialdehyde (MDA) levels, flavonoid content, and PPO enzyme activity increased. PEN application had a positive effect on growth parameters, proline and H 2 O 2 contents, SOD, CAT and POX enzyme activities, but decreased MDA, carbohydrate, flavonoid and anthocyanin contents, as well as PPO activity. According to our results, PEN changed physiological and biochemical parameters, and therefore, due to its low price and availability is suggested for reduction of the negative effects of salinity in sesame.

“…However, the combined application of SA (0.005 mM) and/or Ca 2+ (0.5 mM) increased the phenolic and flavonoid content as well as the total antioxidant scavenging activity, which would help to alleviate the adverse effects of salinity stress on plant growth. Increase in growth and total soluble phenolic and flavonoid content due to SA application (50 and 250 μM) have also been reported in Matricaria chamomilla (Kovacik et al 2009), safflower (Carthamus tinctorius L.) (Shaki et al 2017), and Oueslati olive plants (Olea europaea L.) (Methenni et al 2018). In addition, increases have also been shown in wheat for the combined application of SA and Ca 2+ under saline conditions (Yucel and Heybet 2016).…”

Amaranth (Amaranthus tricolor L.) is a plant that is rich in vitamins, minerals, and phytochemicals. It is grown as a leafy vegetable in marginal environments, but high salinity levels in the soil can have a detrimental effect on its growth. These deleterious effects of salinity can be alleviated by exogenously applying signaling compounds such as salicylic acid (SA) and calcium (Ca), which can improve plant adaptation to stressful conditions. The present study evaluated the physiological and phytochemical responses of red amaranth (Amaranthus tricolor L.) to foliar-applied salicylic acid (SA; 0.005 mM) and calcium (CaSO 4 •2H 2 O; Ca, 2.5 mM) either alone or in combination (SA + Ca) under conditions of 100 mM NaCl salinity. The setup was placed under greenhouse condition from May to October 2017. Treatments without salinity and applied with SA or Ca were used as controls for comparison. Salinity stress reduced the growth and biomass, total chlorophyll contents, and increased electrolyte leakage with Na + and Cl − accumulation in shoot and roots. Nonetheless, exogenous applied SA and/or Ca 2+ reduced the adverse effects of salinity by modulating growth, Na + exclusion from roots, and increased total phenolics, flavonoids, and antioxidant activity in red amaranth. The combined application of salicylic acid and calcium can be a better strategy for improving the salinity tolerance of amaranth under salt-stressed conditions.

“…Our previous work indicated that growth parameters which were followed by measuring fresh and dry weight of safflower plants were remarkably inhibited under different NaCl concentrations. However, the application of SA improved the negative effect of salinity by increasing plant growth especially in 200 mM NaCl-treated plants (Shaki et al 2017). In the current study, some biochemical and molecular parameters were investigated to better understand the effects of exogenous application of SA on safflower plants in saline conditions.…”

“…Our previous works indicated that SA minimizes the negative effects of salt stress by improving growth parameters, accumulation of compatible solutes, and increasing antioxidant activity, and therefore, could be used for partial amelioration of salt stress in safflower (Shaki et al 2017(Shaki et al , 2018. To the best of our knowledge, there is no information available so far about the effect of SA on ions homeostasis, hormonal cross-talk and fatty acids compositions in salt-treated safflower plants.…”

It has been shown that salicylic acid (SA) acts as an endogenous signal molecule responsible for inducing stress tolerance. The aim of the present work is to investigate the effect of sodium chloride (0, 100, and 200 mM) and exogenous SA (1 mM) on some biochemical and molecular responses of safflower. Results revealed that K + , Ca 2+ , indol-3-acetic acid (IAA), and gibberellic acid (GA) contents decreased under salinity however, Na + content, and SOS1 and NHX1 genes expression increased. Further, palmitic and oleic acids contents decreased, while stearic, linoleic, and linolenic acids content increased under salinity. Exogenous SA had a positive effect on K + , Ca 2 + , IAA, and GA contents, but decreased Na + content. In addition, SA induced expression of SOS1 and NHX1 genes in all plants. Our data indicate that SA helps safflower to better cope with salinity. The results provide new insights to mechanisms that help regulate salinity resistance in safflower. SA may be considered as a foliar application to ameliorate salinity effects, due to its low price and availability.
