“…4). The activity of antioxidant enzymes depends on the plant species, organ/tissue, and stress extent (43). Zangeneh and Rasouli [44] stated that in white quince grapes, the SOD enzyme activity increased linearly with the increase of humic acid concentration from zero to 2000 mg/liter.…”

Foliar application of nutrients improves the performance and quality of grapes, and silicon is recently classified as an essential element for plants. For this purpose, a factorial experiment was conducted in a complete randomized design with three replications on grapes cv. ‘Fakhri’. The treatments included three levels of potassium silicate (0, 1000 [S.K1], and 2000 mg.L− 1 [S.K2]), combined with three levels of humic acid (0, 1000 [H1], and 2000 [H2] mg.L− 1). Morphological, physiological, and biochemical characteristics, as well as leaf microelements, were measured. The highest yield (10.56 kg/vine) was obtained with 2000 mg.L− 1 K2SO3×2000 mg.L− 1 humic acid. The interactive effects of these two treatments changed the activity of catalase, peroxidase, and superoxide dismutase, and the content of zinc, manganese, iron, and copper elements in grape leaves increased. This result indicates that potassium silicate and humic acid had a synergistic effect and increased all quantitative and qualitative indices of ‘Fakhri’ grapes studied in this experiment.

“…Ethylene is known to induce respiratory activity, thereby depleting carbohydrates levels (Gonzalez-Candelas et al, 2010;John-Karuppiah and Burns, 2010). On the other hand, ethylene is also involved with flower abscission by triggering abscission zone formation (Van Doorn, 2002) and by oxidative stress promoted by ROS, including the overproduction of superoxide anion (O 2 − ) and hydrogen peroxide (H 2 O 2 ) (Rogers and Munné-Bosch, 2016;Ren et al, 2017;Jędrzejuk et al, 2018;Bayanati et al, 2019).…”

Selenium (Se) is considered a beneficial element in higher plants when provided at low concentrations. Recently, studies have unveiled the interactions between Se and ethylene metabolism throughout plant growth and development. However, despite the evidence that Se may provide longer shelf life in ethylene-sensitive flowers, its primary action on ethylene biosynthesis and cause-effect responses are still understated. In the present review, we discuss the likely action of Se on ethylene biosynthesis and its consequence on postharvest physiology of cut flowers. By combining Se chemical properties with a dissection of ethylene metabolism, we further highlighted both the potential use of Se solutions and their downstream responses. We believe that this report will provide the foundation for the hypothesis that Se plays a key role in the postharvest longevity of ethylene-sensitive flowers.

“…Depending on the nature of metal cofactors present in the structure plant SODs, they are classi ed into three main groups, including MnSOD, FeSOD, Cu/ZnSOD (Saibi and Brini 2018). MnSOD gene was differentially expressed in rose (Bayanati et al 2019) and strawberry (Christou et al 2013) in response to NaCl-induced salinity stress. The seedlings of a salttolerant pea cultivar represented higher transcript levels of MnSOD, CuZnSOD, phospholipid hydroperoxide glutathione peroxidase (PHGPX), and cytosolic GR and APX in comparison to seedlings of the salt-sensitive cultivar (Hernández et al 2000).…”

Salinity is one of the most crucial abiotic stresses which is the consequence of increase in the concentration of NaCl ions influencing plant’s growth, development, and yield. Gama-butyric acid gamma (GABA) is a non-protein amino acid involved in various metabolic processes that accumulates in many plant species during stress conditions. The present study was aimed to evaluate the effect of GABA (0 and 25 mM) and salinity (3 and 5 dS/m) on physiological characteristics and expression pattern of some salinity-related genes in strawberry cv. Aromas under soilless culture condition 12, 24, and 36 h after treatments’ initiation. Based on the results, salinity increased the content of H2O2, MDA, and proline while it decreased the percentage of MSI and the activity of SOD and POD antioxidant enzymes. In contrast, the implementation of GABA not only decreased H2O2 and MDA content, and maintained MSI percentage, but also it improved the activity of antioxidant enzymes and the transcription level of DREB, cAPX, MnSOD, and GST genes. Under non-stress conditions, GABA acted as a mild stressor by imposing effects similar to abiotic stress which could help plants adapt under the adverse environmental conditions. We concluded that strawberry plants represented a higher salinity tolerance by enhancing both enzymatic and non-enzymatic antioxidant physiological protection mechanisms and also by increasing the transcription of salinity-related genes upon GABA application.
