“…Exogenous application of MeJA or SA suppressed the production of the oxidative stressors, while MeJA + SA showed statistically significant effects in drought-stressed French bean plants Figures 4 and S2B). These findings are in accordance with previous studies showing that combined treatments with MeJA and SA reduced the levels of oxidative stress indicators in maize seedlings under drought [27] and in Eureka lemon under chilling stress [30].…”

“…The exogenous application of these two hormones together to mustard [18,24], grasses [25], jatropha [22], Verbascum [26], and maize [27] has been shown to protect plants against abiotic stresses, including drought, by regulating important physiological processes ranging from photosynthesis to nitrogen and proline metabolism and by activating the antioxidant defense system. Previous studies on wheat [28], maize [27], sweet potato [29], and Eureka lemon [30] have suggested that treatment with 5-20 µM MeJA and/or 0.5-2 mM SA effectively enhances the defense signaling routes to mitigate damage due to the abiotic stresses.…”

Drought stress impairs the normal growth and development of plants through various mechanisms including the induction of cellular oxidative stresses. The aim of this study was to evaluate the effect of the exogenous application of methyl jasmonate (MeJA) and salicylic acid (SA) on the growth, physiology, and antioxidant defense system of drought-stressed French bean plants. Application of MeJA (20 μM) or SA (2 mM) alone caused modest reductions in the harmful effects of drought. However, combined application substantially enhanced drought tolerance by improving the physiological activities and antioxidant defense system. The drought-induced generation of O2●− and H2O2, the MDA content, and the LOX activity were significantly lower in leaves when seeds or leaves were pre-treated with a combination of MeJA (10 μM) and SA (1 mM) than with either hormone alone. The combined application of MeJA and SA to drought-stressed plants also significantly increased the activities of the major antioxidant enzymes superoxide dismutase, catalase, peroxidase, glutathione peroxidase, and glutathione-S-transferase as well as the enzymes of the ascorbate–glutathione cycle. Taken together, our results suggest that seed or foliar application of a combination of MeJA and SA restore growth and normal physiological processes by triggering the antioxidant defense system in drought-stressed plants.

“…It is worth noting that methyl dihydrojasmonate (MDHJ), a volatile likely involved in fruit cold response, was not detected in freshly-harvested fruit and appeared toward the end of storage at both temperatures ( Table 2). The implication of MDHJ in chilling tolerance has been explored (Cao, Zheng, Wang, Jin, & Rui, 2009) and its postharvest application has been shown to increase cold tolerance in lemon (Siboza & Bertling, 2013). Based on these observations, the emission of this compound could be a consequence of the development of peel damage or part of key signaling mechanisms triggered in response to chilling injury.…”

Grapefruits are sensitive to develop chilling injury (CI) on the peel upon postharvest storage at low temperature. We investigated the influence of the storage at 2 and 12 ºC on CI, carotenoids, and emission of volatiles by intact fruit. CI symptoms at 12 ºC were restricted to green fruit peel sectors but at 2 ºC the CI severity was higher and distributed through the whole fruit surface. Fruit peel coloration and carotenes content increased at 12 ºC whereas experienced minor changes at 2 ºC. At 2 ºC the emission of total volatiles and specific monoterpenes, mainly limonene, but also linalool and terpineol was enhanced, while storage at 12 ºC resulted in higher emission and diversity of cyclic sesquiterpenes and aliphatic esters. Results indicate a selective emission of volatiles by intact red grapefruit that appears to be a specific response to the storage temperature or to the cold-induced damage.

“…For example, dipping lemon in 2 mM SA solution for 30 s reduced ROS accumulation, reduced CI symptoms, but increases the antioxidant capacity during storage at −0.5°C for 42 days 7 . Treatments with SA derivatives, such as methyl salicylate (MeSA) and acetylsalicylic acid (ASA) also reduced CI symptoms of pomegranate during storage at 2°C for 84 days, by increasing the total antioxidant capacity (TAC) and the contents of total phenolic compounds and anthocyanin 8,9 .…”

ABSTRACT:The effects of salicylic acid (SA) on reactive oxygen species (ROS) and the antioxidant defence system of mango fruits cv. Nam Dok Mai No. 4 in cold storage were evaluated. Mature mangos were dipped in 1 mM SA and distilled water (as control) for 10 min and stored at 5 ± 1°C with 90 ± 2% RH for 42 days. Chilling injury (CI) and ROS levels including superoxide radical (O · -2 ), hydrogen peroxide (H 2 O 2 ) and hydroxyl radical (HO · ) in the exocarp were measured every 7 days. The level of antioxidant system components, viz., enzymatic antioxidants: enzyme activity and gene expression of superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX); and nonenzymatic antioxidants: ascorbic acid, total glutathione and total phenolic contents, total antioxidant capacity (TAC) were determined. In the control fruits, the levels of O · -2 , H 2 O 2 and HO · increased during storage with a decrease in ascorbic acid and total glutathione contents, while total phenolic content, TAC, enzyme activities, and gene expression of SOD, CAT, and APX increased during the first 21 days of storage but thereafter gradually decreased. CI symptoms appeared in the control fruits on day 21 and rapidly increased thereafter. During storage, SA-treated mango fruits exhibited significantly higher activities of SOD, CAT, and APX; and increased levels of ascorbic acid, total glutathione, total phenolic compounds, and TAC compared to that of the control fruits. High activities of antioxidant enzymes were associated with higher gene expression, which was correlated with the reduction of CI in SA-treated fruits. We conclude that during cold storage, the SA-treatment strengthens the antioxidant defence system reducing CI in mango fruits cv. Nam Dok Mai No. 4 during cold storage.
