“…This decline is related to the distracted scavenging activity of this enzyme (Shahbazi et al, 2011). This finding was in line with those of Ahmad Sajid et al (2016), Yordanova and Popova (2007) and Esfandiari Ghalati et al (2020). SA adjusts the antioxidant capacity of the salt exposed-plants via increasing or inhibiting the activity of antioxidant enzymes including catalase, superoxide dismutase and ascorbate peroxidase (Ahmad et al, 2018;El-Esawi et al, 2017;Li et al, 2014;Pirasteh-Anosheh and Emam, 2018).…”

“…Over recent decades, some efforts have been introduced as efficient strategies to lessen the destructive impacts of salt stress on plant metabolism, i.e. the exogenous applications of putrescine (Esfandiari Ghalati et al, 2020), nitric oxide (Kaya et al, 2019), proline (Freitas et al, 2019) and salicylic acid (Naser Alavi et al, 2014).…”

“…According to the Iranian Ministry of Agriculture statistics, from 14,000 hectares of tropical fruits plantation, 1750 ha dedicated to guava and the yearly production of guava in Iran is about 4119 tons (The center of information and technology, 2019). The impacts of NaCl on the seed germination (Hooda and Yamdagni, 1991), young (Cavalcante et al, 2007;Esfandiari Ghalati et al, 2020) and mature plants (Ali-Dinar et al, 1999) of guava have demonstrated its destructive effects.…”

The rising demand for guava fruit worldwide is due to its richness in vitamin C, high yielding and two bearing seasons. Given the salt stress threat to guavas and the necessity of protective strategies, in the present research guava seedlings were subjected to sodium chloride (0 and 50 mM) and salicylic acid (0 and 1 mM). To ascertain a logical conclusion, the activity of antioxidant enzymes, antioxidant capacity of DPPH, ferric reducing antioxidant power, total flavonoid and phenol contents were monitored in saltexposed guava seedlings. Based on our findings, the most superoxide dismutase (87.46 µmol min −1 g −1 DW) activity, ferric reducing antioxidant power (408.82 mmol g −1 DW), DPPH scavenging activity (80.65%), flavonoid (14.15 mg QE −1 g DW) and phenol (34.02 mg GAE g −1 DW) contents were found in 50 mM NaCl-exposed plants, which were enriched by 1 mM salicylic acid. A high correlation was observed among non-enzymatic antioxidant parameters (DPPH scavenging activity, ferric reducing antioxidant power, total flavonoid content and total phenol content). In conclusion, salicylic acid improved guavas salt tolerance by increasing both enzymatic (peroxidase and superoxide dismutase) and non-enzymatic (ferric reducing antioxidant power, DPPH scavenging activity, total phenol and flavonoid contents) pathways.

“…Plants express both enzymatic and nonenzymatic antioxidant activities to thwart stress-induced oxidative damage [63]. In this study, the N5 treatment prompted a decrease in the antioxidant enzymes' activity (CAT, POD, and SOD), with concomitant low proline and malondialdehyde (MDA) contents, which might be associated with the level of salinity exposure.…”

Salinity is a major constraint in improving agricultural productivity due to its adverse impact on various physiological and biochemical attributes of plants, and its effect on reducing nitrogen (N) use efficiency due to ion toxicity. To understand the relationship between sodium chloride (NaCl) and increased N application rates, a pot study was performed in which the ammonical (NH4+) form of N was applied as urea to maize crops at different rates (control, 160, 186, 240, 267, 293, and 320 kg N ha−1) using two salinity levels (control and 10 dS m−1 NaCl). The results indicate that all biochemical and physiological attributes of the maize plant improved with increased concentration of N up to 293 kg ha−1, compared to those in the control treatment. Similarly, the optimal N concentration regulated the activities of antioxidant enzymes, i.e., catalase activity (CAT), peroxidase activity (POD), and superoxide dismutases (SOD), and also increased the N use efficiencies of the maize crop up to 293 kg N ha−1. Overall, our results show that the optimum level of N (293 kg ha−1) improved the salinity tolerance in the maize plant by activating stress coping physiological and biochemical mechanisms. This may have been due to the major role of N in the metabolic activity of plants and N assimilation enzymes activity such as nitrate reductase (NR) and nitrite reductase (NiR).

“…In addition, foliar treatment of salt-tolerant rice under salt stress increased shoot growth, grain yield and proline content, inhibited Na + and Cl – uptake, and prevented chlorophyll degradation ( Krishnamurthy, 1991 ). It also improved salt tolerance of yellow guava seedlings ( Psidium guajava L.) ( Esfandiari Ghalati et al, 2020 ). The exogenous application of Put also proved to be very effective in increasing the growth, photosynthetic pigments, yield and quality of onions ( Allium cepa ), offering better results than the application of Glu.…”

Pure Organic Active Compounds Against Abiotic Stress: A Biostimulant Overview

et al. 2020

View full text Add to dashboard Cite

Biostimulants (BSs) are probably one of the most promising alternatives nowadays to cope with yield losses caused by plant stress, which are intensified by climate change. Biostimulants comprise many different compounds with positive effects on plants, excluding pesticides and chemical fertilisers. Usually mixtures such as lixiviates from proteins or algal extracts have been used, but currently companies are interested in more specific compounds that are capable of increasing tolerance against abiotic stress. Individual application of a pure active compound offers researchers the opportunity to better standarise formulations, learn more about the plant defence process itself and assist the agrochemical industry in the development of new products. This review attempts to summarise the state of the art regarding various families of organic compounds and their mode/mechanism of action as BSs, and how they can help maximise agricultural yields under stress conditions aggravated by climate change.
