“…At the stage of 30 DAS, the foliage of the resulting plants was sprayed with 10 -5 M of salicylic acid (SA), except control which received double distilled water (DDW) instead of SA. The concentration of SA was selected on the basis of our earlier experiments (Hayat et al, 2010). The plant samples were collected at 60 and 90 DAS to assess various growth and physiological parameters.…”

The present study was designed with an objective to elucidate the effect of the exogenous application of 10 -5 M of salicylic acid (SA) to the foliage of the chickpea plants exposed to 0, 25, 50 or 100 mg cadmium (Cd) per kg of soil. The foliage of the plants grown in soil amended with varying doses of Cd was sprayed with 10 -5 M of SA at 30 days after sowing (DAS). The plant samples were collected at 60 and 90 DAS to assess various parameters. The damage caused due to the Cd exposure was partially overcome by the exogenous application of SA. The SA treatment resulted in a significant increase of growth, photosynthesis, yield and the activity of antioxidative enzymes viz. catalase, peroxidase and superoxide dismutase in the plants exposed to 0, 25 or 50 mg Cd per kg of soil. However, the treatment did not prove to be fruitful in alleviating completely the stress generated by 100 mg Cd per kg of soil.

“…27 Understanding how planted forest trees tolerate low water 28 availability, studying new insights to anticipate its impacts and al pathways (Kissoudis et al, 2014) lead to changes in the biological 48 responses for the maintenance of plant stress tolerance (Wang and (Pastor et al, 1999). 61 The exogenous application of SA has been considered a short-62 term solution to improve the adverse effects of water deficit on 63 plants (Singh and Usha, 2003), however the precise mode of SA 64 action remains unclear (Hayat et al, 2010), in particular for trees. 65 Research on SA application and water deficit tolerance in 66 Eucalyptus species remains completely absent.…”

A B S T R A C TEucalyptus genus is the most widely planted hardwood tree, which productivity and development are limited by low water availability. Plant drought tolerance can be managed by adopting strategies, such as the exogenous application of salicylic acid. The main objective of the present study was to assess whether the exogenous foliar salicylic acid application would ameliorate the damages of water deficit on Eucalyptus globulus plants. Plants were watered at 70% (well water) or 15% (water deficit) of field capacity and four concentrations of salicylic acid (0, 0.75, 2.5 and 5.0 mM) were applied. Water potential, total chlorophylls and carotenoids contents, chlorophyll fluorescence parameters, leaf gas exchange, malondialdehyde, total soluble sugars, starch and total phenols contents were measured. The global hormonal content was quantified by ultra-performance liquid chromatography-mass spectrometry and specific local dynamics of indolacetic acid and abcisic acid were detected by immunolocalization in leaves. A multivariate statistical approach was used to get an overview of the plant physiological status. E. globulus water deficit response included growth rate decline associated with reduced in both water potential and leaf gas exchange parameters. Plant water deficit defence strategies led to an increase in total chlorophylls and carotenoids contents, lipid peroxidation, phenols and total soluble sugars. Six from the 18 hormones detected increased in water deficit plants. Exogenous salicylic acid application improved water deficit tolerance of E. globulus by improving water potential with a positive impact in primary metabolism (photosynthetic rate, soluble sugars) but also in secondary metabolism and defence mechanisms (higher total phenols and less lipid peroxidation) in the highest salicylic acid concentrations. Also, changes in endogenous levels of abscisic and salicylic acids, gibberellins 4 and 7, and specific cytokinins were found in water deficit plants with salicylic acid application. Our results indicated that salicylic acid application could be a potential chemical priming strategy to ameliorate water deficit effects on E. globulus plants.

“…Hayat et al (2005) reported that the pigment content was significantly enhanced in wheat seedlings raised from grains pre-treated with a low concentration (10 -5 M) of SA, whereas higher concentrations were not beneficial [74]. However, a reduction in chlorophyll content was observed in plants pre-treated with SA [56] [75] [76]. The present study showed that changes on the pigment contents were more sensitive to quizalofop-p-ethyl and quizalofop-p-ethyl + SA (Figures 9-12).…”

“…In plants, phenols are hypothesised to have many functions, including protection against UV-B radiation and defence against pathogen attack and wounds [55]. When applied exogenously at suitable concentrations, SA enhanced the efficiency of antioxidant systems in plants [56]. Phenolic compounds are antioxidants that accumulate in plants under stress [57].…”

Herbicides adversely affect both the target plant and its environment. In this study, Helianthus annuus L. cv. "Oliva CL" was treated post-emergence with 0.3 to 3.1 mM quizalofop-p-ethyl. The peroxidase activity (POD), ascorbate peroxidase activity (APX), lipid peroxidation, pigment system and total phenolic content were then determined on the 1st, 5th, 10th and 15th days following treatment. The POD activity increased on all application days, and the APX activity increased on the 5th day and decreased on the 10th and 15th days. In addition, the malondialdehyde (MDA) content was increased on the 1st, 5th, 10th and 15th days, except for the in H. annuus plants treated with 1.6 to 3.1 mM quizalofop-p-ethyl. The total chlorophyll, carotenoid and total phenolic content were important and changed in a time dependent manner. In the present study, we also investigated the possible role of salicylic acid (SA) in protecting H. annuus seedlings from herbicide toxicity. The plants were first treated with 0.5 mM SA pre-emergence and then treated with 0.3 to 3.1 mM quizalofop-p-ethyl herbicide post-emergence. In general, increases in the POD activity and MDA content were observed in the treatment groups on all application days. In the treated groups, the APX activity increased until the 15th day. In the SA pre-treated plants, the total phenollic, total chlorophyll and carotenoid content were also important in a time dependent manner.
