“…In the other side, the concentrations of total phenols and total antioxidant activity of leaves and fruits of olive plants were higher than of figs plants. The above results agreed with those obtained by Sulaiman and Hassan (2011), Mujić et al(2012), Malek and Sanaa (2013) and El-Sayed et al (2014).…”

The main source of irrigation water to fig and olive trees in the Northwestern Coast of Matrouh Province is rains water which is starting from October or November until February and March every year. In some areas, possible use supplementary irrigation water system from wells water after the rainy season is ens. The most soils of the Northwestern Coast are calcareous soils which are different in the calcium carbonate content from one region to another. Regarding to the mineral fertilizers functions in plant; the macronutrients functions in plant such as; the photosynthetic processes in leaves and plant growth were remarkably improved by high nitrogen nutrition. Nitrogen contributes greatly in the formation of the following, protein synthesis, necessary component in cell structure, leafy growth and carbohydrate production (Cechin & Fumis, 2004 and Weisany et al., 2013). Phosphorus involved in the photosynthesis, energy and nutrient transport in plant, it can establish a strong root base and produce strong all through the growth plant stages (Ceulemans et al., 2011 and Lambers et al., 2014). Potassium is involved in many processes in plant such as photosynthesis, water retention and uptake of the plant, protects plant from frost, reduce it disease in root, shoots and leaves of the plant, has good characteristics quality such as producing of uniform size, color and maturity, with enhanced flavor, free of blemishes and devoid of any sign of diseases (Britto and Kronzucker, 2008 and Wang et al., 2013). The micronutrients functions in plant such as; Iron (Fe) involves for many processes in plant such as the process of absorption from the soil through the roots, control transfers from the roots to the parts of the plant above soil surface, the intensification of the iron concentration in the mitochondria and chloroplasts and during seed germination and reduce the presence of iron in the wood (Conte and Walker, 2011). Iron deficiency leads to facilitate the transfer of heavy metal such as manganese, zinc, cobalt, and cadmium, while sufficient level or above of iron prevents it (Barberona et al., 2014). Plant's ability to withhold iron and redistribute within the plant for non-iron link the causes of infectious diseases to the presence of competing on the iron link between them and thus increase the plant's ability to cope with such infectious diseases (Expert et al., 2012). Manganese (Mn) plays an important role for many processes in plant such as oxidation and reduction processes in plants, such as the electron transport in photosynthesis, in chlorophyll production, as an activating for more 35 different enzymes and carbohydrates synthesis (Mousavi et al., 2011). Zn influences the activity of plant enzymes, hydrogenase, carbonic anhydrase and synthesis of cytochrome, Zn involves in plant carbohydrate metabolism, maintenance of the integrity of cellular membranes, protein synthesis, regulation of auxin synthesis and pollen formation, Zn has positive effect on water uptake and transport in plants and also reduces the adve...

“…Jasmonic acid and its related compounds, which can be identified in many plant species, have been regarded as endogenous regulators of both abiotic and biotic stress-induced responses, and also as influential signal molecules in the responses to stresses [3]. The ability of JA to stimulate the expression of proteins putatively involved in plant defense such as peroxidases [21] has been associated with an increase in natural plant resistance to stress conditions. Previous reports have also indicated that exogenous application of JA could be used as a beneficial tool for the control and management of some biotic and abiotic stresses in different plant species such as wheat [22], maize [23], tomato [24], but few studies have highlighted the effect of appropriate concentrations to mitigate drought stress in cotton [25].…”

Precise and appropriate management of farmland for a cotton crop to reach the highest water use efficiency with a low water supply and an acceptable yield is required in arid- and semiarid regions. This study in Iran aimed to find the most appropriate concentration of jasmonic acid (JA) and the best stage for application to cope with any negative impacts of water deficit stress. A split-plot factorial experiment based on a randomized complete block design with three replications was used in 2 consecutive years (2016–2017). Two irrigation intervals of 10 and 20 days were used, with four concentrations of JA (0, 25, 50, and 100 mg L<sup>−1</sup> ) and applications at three crop stages (vegetative, reproductive, and vegetative and reproductive together). The final results showed that the 20-day interval significantly decreased relative water content, the quantity of cotton, cotton yield and its related traits including boll number per plant, the 1,000-seed weight, seed cotton yield, lint yield, and lint percentage. It also increased the content of proline and soluble sugars. The 50-mg L<sup>−1</sup> concentration of JA applied at the vegetative-reproductive stages appropriately mitigated the negative effects of water deficit. These results are of practical application for farmers in arid- and semiarid regions with low water supply when irrigating cotton lands in order to reach an acceptable cotton yield.

“…Among them, the most important are antioxidant enzymes such as peroxidases (POD), catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR), dehydroascorbate reductase (DHAR), monodehydroascorbate reductase (MDAR), glutathione peroxidases (GPX), or glutathione s-transferase (GST) (Yan et al, 2013;Hossain and Dietz, 2016;Sukweenadhi et al, 2018). Non-enzymatic components include glutathione, ascorbic acid, tocopherol, phenolic or polyphenolic compounds (Yan et al, 2013;El-Sayed et al, 2014;Fatma et al, 2014;El-Esawi et al, 2018a). To some species of endophytic fungi or ectomycorrhizal fungi are attributed antioxidant properties that could improve plant's resistance to plant's endogenous reactive oxygen species.…”
