“…Certain studies also showed that the MDA content decreased in the SA treatment during cold stress in watermelon (Yang et al 2008) and bamboo (Luo et al 2012). SA also alleviates abiotic stress-induced oxidative damage as indicated by a downregulation in lipid peroxidation (MDA level) in plants (Posmyk et al 2005;Huang et al 2008;Yang et al 2008;Luo et al 2012). In addition to these, the MDA results showed that exogenous SA applied before cold stress could previously prepare barley plants against cold damage and this protective effect could be seen for 24 days after it was applied.…”

In this work, the time-dependent effect of exogenous salicylic acid (SA) applied before cold stress was investigated on the regulation of antioxidative respond mechanisms in two barley (Hordeum vulgare L.) cultivars (Akhisar and Tokak) differed in cold tolerance. SA (0.1 mM) was applied to 7-days old barley seedlings growing under control conditions (20/18°C). After this application, the seedlings were transferred to cold conditions (7/5°C) at different times (7, 14, 21 and 28 days) for 3 days. Then, the contents of malondialdehyde (MDA), hydrogen peroxide (H 2 O 2 ) and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) were determined in the leaves (control, cold and SA + cold) from the seedlings harvested at 10, 17, 24 and 31 days. Moreover, the effect of cold stress was evaluated on the endogenous SA level at the both cultivars by comparing to control plants. The MDA content increased in the cold treatment while it decreased in the SA treatment at all the days studied at the both cultivars. The SA + cold treatment could have a variable effect on H 2 O 2 content at the tolerant barley (Tokak) while decreased its content at the sensitive cultivar (Akhisar). The SA + cold treatment could increase the activities of POX and SOD at both cultivars, but it increased the CAT activity at the tolerant cultivar while decreased at the sensitive cultivar. In addition, the content of endogenous SA was decreased by cold stress at all the days studied at the barley cultivars as compared to control plants. The results show that the SA treatment could be effective on the regulation of the parameters studied at cold conditions until 31 days after SA application, and the importance of exogenous SA treatment before cold stress. It was concluded that exogenous and endogenous SA could play an ameliorating role on cold tolerance by regulating reactive oxygen species and the activities of antioxidative enzymes in both cold-sensitive and cold-tolerant cultivars of barley.

“…Although the MDA concentration increased in GABA treated seedlings, the magnitude of this increase was less than seedlings not treated with GABA (Table 2). It seems that GABA decreased the accumulation of lipid peroxidation product, MDA, which is regarded as an indicator of the loss of structural integrity in membranes subjected to chilling stress (Posmyk et al 2005). It was observed that proline amount increased in tomato seedlings after chilling stress (86.15 μmolg-1FW compared to control 17.1 μmolg-1FW).…”

“…Superoxide dismutase (SOD) activity was assayed by measuring its ability to inhibit the photochemical reduction of nitro blue tetrazolium chloride (NBT) using the method of Posmyk et al (2005). Catalase (CAT) activity was assayed by measuring the rate of disappearance of hydrogen peroxide (Hernandez et al 2001).…”

Low temperature during germination and early seedling growth is one of the most significant limiting factors in the productivity of plants. Tomato seedling germination is sensitive to chilling stress. Gamma-aminobutyric acid (GABA), as a non-protein amino acid, involved in various stress tolerances in plants. In this study, 5-day old tomato seedlings were exposed to chilling stress (2±0.05°C for 48 h) and then the effects of 0, 100, 250, 500 and 750 μmolL −1 concentrations of GABA on electrolyte leakage, proline and malondialdehyde (MDA) content were investigated. The resultS showed that the antioxidant enzyme activity, electrolyte leakage, MDA and proline content were significantly reduced by GABA treatments. However under chilling stress seedlings treated with GABA exhibited significantly higher sugar and proline contents as compared to un-treated seedlings. These results suggest that GABA treatment protects tomato seedlings from chilling stress by enhancing some antioxidant enzymes activity and reducing MDA content which results in maintaining membrane integrity.

“…Membrane lipid peroxidation may be one of the first events in the manifestation of CI, in which phase MDA was produced and damaged to cell membrane (Imahori et al 2008). Posmyk et al (2005) suggested that the MDA levels in a tissue can be a good indicator of the membranes integrity of plants subjected to low temperature. Lipid peroxidation is one of the adverse effects of CI on plant cells leading to MDA accumulation.…”

Alleviation of postharvest chilling injury of tomato fruit by salicylic acid treatment

et al. 2012

Tomato fruit at the mature green stage were treated with salicylic acid at different concentration (0, 1 and 2 mM) and analyzed for chilling injury (CI), electrolyte leakage (EL), malondialdehyde (MDA) and proline contents and phospholipase D (PLD) and lipoxygenase (LOX) activities during cold storage. PLD and LOX activities were significantly reduced by salicylic acid treatment. Compared with the control fruit, salicylic acid treatment alleviated chilling injury, reduced electrolyte leakage, malondialdehyde content and increased proline content. Our result suggest that the reduce activity of PLD and LOX, by salicylic acid may be a chilling tolerance strategy in tomato fruit. Inhibition of PLD and LOX activity during low temperature storage could ameliorate chilling injury and oxidation damage and enhance membrane integrity in tomato fruit.
