“…The results of oxidative stress scavengers’ activity showed that melatonin improved certain parameters at a higher rate with one bacterial inoculant over the other, indicating preferential induction/synergism of some microbes with melatonin. Melatonin has been reported to regulate rhizogenesis and fortify reactive oxygen species (ROS) scavenging mechanisms, root architecture, photosynthetic capacity, and ionic balance of plants under salinity stress ( Yan et al., 2020 ; Altaf et al., 2021 ).…”

“…There have been a few reports on the improvement in plant performance after the combined application of microbes and melatonin (Liu et al, 2021b), which support our results that show synergistic effects with bacterial inoculants and melatonin. Yan et al (2020) reported that pre-treatment with melatonin reduced membrane damage and oxidative stress in rice under salinity. Thus, the stage of application, as well as the concentration are crucial for the melatonin role.…”

In this study, rhizospheric and endophytic bacteria were tested for the alleviation of salinity stress in rice. Endophytic isolates were taken from previous studies based on their salt stress-alleviating traits. The rhizospheric bacteria were isolated from rice and screened based on salt tolerance and plant growth-promoting traits. Molecular identification indicated the presence of class Gammaproteobacteria, Bacillota, and Actinomycetia. Two-two most potential isolates each from rhizospheric and endophytic bacteria were selected for in planta trials. Results showed that microbial inoculation significantly improved germination and seedling vigor under elevated salinity. The confocal scanning laser microscopy showed higher bacterial colonization in inoculated rice roots than in control. Based on this experiment, rhizospheric bacteria Brevibacterium frigoritolerans W19 and endophytic Bacillus safensis BTL5 were selected for pot trial along with a growth-inducing compound melatonin 20 ppm. Inoculation of these two bacteria improved the levels of chlorophyll, proline, phenylalanine ammonia-lyase, catalase, superoxide dismutase, polyphenol oxidase, root-shoot length, and dry weight under elevated salt concentration. The gene expression studies showed modulation of SOD1, CATa, NHX1, and PAL1 genes by the bacterial strains and melatonin application. The inoculation was found to have additive effects with 20 ppm melatonin. This enhancement in dry matter accumulation, compatible solute production, and oxidative stress regulation could help plants in mitigating the ill effects of high salinity. Exploring such a combination of microbes and inducer molecules could be potentially useful in developing stress-alleviating bioformulations.

“…The root system also has the capability to inhibit the uptake and translocation of toxic ions to other tree parts [ 69 ]. Identification of tolerant/sensitive germplasm is clearly based on the root architecture of fruit trees and the ability of the root system to inhibit toxic ions from the soil [ 70 ].…”

Fruit orchards are frequently irrigated with brackish water. Irrigation with poor quality water is also a major cause of salt accumulation in soil. An excess of salts results in stunted growth, poor yield, inferior quality and low nutritional properties. Melatonin is a low molecular weight protein that shows multifunctional, regulatory and pleiotropic behavior in the plant kingdom. Recently, its discovery brought a great revolution in sustainable fruit production under salinity-induced environments. Melatonin contributed to enhanced tolerance in Zizyphus fruit species by improving the plant defense system’s potential to cope with the adverse effects of salinity. The supplemental application of melatonin has improved the generation of antioxidant assays and osmolytes involved in the scavenging of toxic ROS. The tolerance level of the germplasm is chiefly based on the activation of the defense system against the adverse effects of salinity. The current study explored the contribution of melatonin against salinity stress and provides information regarding which biochemical mechanism can be effective and utilized for the development of salt-tolerant germplasm in Zizyphus.

“…Exogenous application of MT decrease salt inhibition for plants growth as well as increase biomass accumulation (Jiang et al, 2016). In addition, MT application increased growth attributes, accumulation of biomass and improved assimilation of carbon in plant tissues due to increase the photosynthetic rate and pigments content under stress conditions (Hernández-Ruiz et al, 2005 andYan et al, 2020).…”

Maximizing use of water unit is one of the most important approach of sustainable agricultural development from agricultural policy-makers view around the world in the past and the future. Also, agriculture sector actively consumes large amounts of fresh water share in Egypt. Agricultural drainage water represents a significant percentage of water if it is reused again by raising its quality. So, this could be obtained by using magnetic technology (water/filed) as a means of mitigation lack of water by reusing agriculture drainage water in vegetable crops irrigation like tomato and studied plant productivity under these conditions. The objectives of this research were to evaluate the efficiency of magnetized drainage water and some anti-stressors on tomato plants behavior under Delta region conditions. The data presented in this paper are the results of two field experiments and it was observed that irrigation magnetic agriculture drainage water superior untreated plants in their effects on most of studied parameters. Concerning anti-stressors treatments, melatonin followed by glycine betaine recorded the best effects on plant growth, chemical composition, enzymes activity as well as yield and fruit quality parameters in both seasons. However, plants irrigated with drainage water only achieved the lowest values of all parameters as a result of salinity stress except fruit quality. The most concluded treatment of the superior positive effect on tomato plant productivity was irrigation with magnetized drainage water with foliar spray with melatonin, also it may be considered as the best option to save water under its scarcity and limited sources.
