Effects of Salicylic Acid on Triticale under Salt Stress

Abstract

The goal of this study was to determine the effect of salicylic acid (50 µM) on triticale grown under salt stress. In this study, we investigated shoot and root lengths, malondialdehyde, proline, ion leakage, relative water content, chlorophyll content. The results indicated that salicylic acid is quite effective to deal with salt stress. Anatomically shoot (3%) and root lengths (4%), as well as relative water content (12%) and chlorophyll content (9%), were increased by salicylic acid under salt toxicity by comparison to merely the salt application. Moreover, according to the only salt stressed plant, malondialdehyde, proline, and ion leakage were decreased 7%, 26%, 23% respectively by the application of salicylic acid in shoot tissues under salt stress. Similarly, SA decreased malondialdehyde, proline and ion leakage in root tissues under salt stress. Overall our results indicated that salicylic acid can be used for agricultural production of triticale under salt stress.

Salicylic acid and thiourea ameliorate the negative impact of salt stress in wheat (Triticum aestivum L.) seedlings by up-regulating photosynthetic pigments, leaf water status, and antioxidant defense system

“…Among the potential endogenous hormones, salicylic acid (SA), and thiourea (TU) has been marked assuming a very noteworthy role in plant growth and development and impact a wide assortment of plant physiological processes, ion uptake and transportation, proline metabolism, and plant water relations by minimizing salt toxicity under stress situations (Wakchaure et al, 2018;Kaya et al, 2019). The shoot and root length, chlorophyll content, relative water content was found to increase whereas malondialdehyde, proline and ion leakage were decreased after application of SA in Triticale under saline condition (Erkan and Aras Aşci 2021). Furthermore, both TU and SA serve as a critical signalling molecule for counteracting the negative effects of ROS induced oxidative stress by the enhancement of antioxidant enzyme activity such as CAT, APX, and POD (Patade et al, 2012;Yadu et al, 2017;Kaya et al, 2020).…”

In addition, numerous reports demonstrated that salt stress caused a significant increase in MDA content on rice and maize which was prevented by SA treatments (Erkan & Aras Aşci, 2021;Pandey et al, 2021). Several previous studies also reported that priming with exogenous SA and TU was found to mitigate the salt stress in rice (Oryza sativa), onion (Pisum sativum), potato (Solanum tuberosum), faba bean (Vicia faba), mung bean (Vigna radiata), and lentil (Lens culinaris) by intensifying the activities of antioxidant enzymes and osmotic adjustment and by promoting root and shoot formation and by stimulating flowering (Mani et al, 2012;Mostofa & Fujita 2013;Khan et al, 2014;Ahmad et al, 2017;Nooren et al, 2017;Nie et al, 2018;El-Kinany, 2020;Yadav et al, 2020;Pandey et al, 2021).…”
