“…In our study, we found that SA or SNP significantly decreased the root dry mass, however, the treatments of SA + SNP increased the dry mass of shoots and plant height under UV-B stress (Table 1). These results are in an agreement with the growth stimulation by SA in mung bean seedlings (Singh et al 2014) and alleviation of UV-B stress by NO in wheat (Fu et al 2013). It is possible that under UV-B stress the better performance of plants treated with SA, SNP, or SA + SNP is mainly associated with higher activities of antioxidant enzymes and direct ROS scavenging capacities.…”

“…Previous studies have shown that SA was direct scavenger that protects plants from oxidative damage (Li et al 2014, Singh et al 2014, Sheng et al 2015. Additionally, NO protects the plants from oxidation damage by the maintaining cellular redox homeostasis and promoting the transformation of O 2 •-to H 2 O 2 and O 2 and also by enhancing the activities of enzymes scavenging H 2 O 2 (Zheng et al 2009).…”

The effects of exogenous salicylic acid (SA), sodium nitropusside (SNP, a nitric oxide donor), or their combination on dwarf polish wheat (Triticum polonicum L.) seedlings under UV-B stress were studied. UV-B stress significantly decreased plant height, shoot dry mass, pigment content, net photosynthetic rate, intercellular CO 2 concentration, stomatal conductance, transpiration rate, and variable to maximum chlorophyll fluorescence ratio (F v /F m ) in all plants, but less in the presence of SA, SNP, and their combination. On the other hand, there were considerable increases in malondialdehyde, proline, O 2•-and H 2 O 2 content under UV-B stress. When SA, SNP, and their combination were applied, the content of MDA, proline, H 2 O 2 , and O 2 •-was less increased. Moreover, there were considerable increases in activities of superoxide dismutase, peroxidase, ascorbate peroxidase, and glutathione reductase under UV-B stress and more in the presence of SA, SNP, and their combination. Therefore, it is considered that the combination of SA, SNP, and especially their combination can alleviate UV-B stress in dwarf polish wheat.

“…may regulate ROS level directly or indirectly and thus, the antioxidants are an indicative of level of tolerance in plants [21]. In stress condition, the balance between the productions of ROS and antioxidants get disturbed and thus, level of ROS is enhanced to an extent that causes severe damage to the biomolecules [22,23]. ROS directly react with biomolecules cause lipid peroxidation, protein oxidation and DNA mutation [24,25].…”

“…Application of SA enhances the photosynthetic rate and maintains the stability of the cell membrane through regulating enzymatic activity (Ghanta et al, 2014), which eventually alleviated oxidative stress (Wasti et al, 2012), but the underlying mechanism remains unclear (Wang et al, 2014). This effect of SA on oxidative stress response was observed in a variety of plants: Solanum lycopersicum (Manaa et al, 2014;Wasti et al, 2012), Arabidopsis thaliana (Borsani et al, 2001), Vigna radiata (Singh et al, 2014), and Triticum aestivum (Kumar et al, 2015;Li et al, 2013;Zhao et al, 2011). In different T. aestivum cultivars, variations in the expression levels of heat stress-associated proteins have been documented (Kumar et al, 2012).…”

Rhododendrons (Rhododendron) are ornamental plants that exhibit poor thermotolerance. Salicylic acid (SA) and Ca2+ regulate the physiological and biochemical mechanisms in plants adapted to adverse environmental conditions. This study investigated the role of SA and CaCl2 in managing heat tolerance of Rhododendron ‘Fen Zhen Zhu’. Plants of the triennial Rhododendron ‘Fen Zhen Zhu’ were pretreated with SA and CaCl2, alone and combined. Following this pretreatment, the plants were subjected to 38/30 °C (day/night) incubation for 6 days, and then allowed to recover for 20 days under 25/17 °C (day/night) in a chamber. Changes in morphology were observed and recorded. Data were collected on plant chlorophyll content, malondialdehyde (MDA) content, H2O2 level, antioxidant enzyme activity, and total soluble protein content. The results revealed that the plant growth was considerably affected by heat stress, the leaves became brown and withered, and the plant defoliated. Under heat stress, chlorophyll content and total soluble protein levels decreased. Peroxidase (POD) activity and superoxide dismutase (SOD) also decreased, whereas the H2O2 and MDA content increased. Individual or combined application of SA and CaCl2 had a positive effect on plant growth, chlorophyll content, total soluble protein levels, and enzymatic antioxidant activity under heat stress. In general, the effect of the combined application of SA and CaCl2 was superior to individual application. In addition, treatment with high CaCl2 concentrations effectively alleviated the decrease in chlorophyll content. However, at low SA and CaCl2 concentrations, SOD and POD activity and total soluble protein accumulation increased whereas MDA and H2O2 levels decreased. These results suggest that SA and CaCl2 may interact to alleviate heat stress.
