“…The preservation of elevated water status under stress is a prevailing outcome in crop cultivars. The WC, RWC %, and WTC levels in Bi and/or Mt application plants under saline conditions were retained at levels near to the control, as confirmed by previous research [ 28 , 32 , 51 , 58 ]. In the current investigation, salinity drastically decreased WC and RWC, but Bi- and/or Mt-treated borage plants established higher WC and RWC levels than untreated plants ( Table 1 ), which delegated that Bi and/or Mt application played an important role in maintaining superior water relations and enhanced the salinity tolerance of borage.…”

“…The increase in water preservation with Bi and/or Mt in stress-exposed plants might be coupled with (i) stomatal closure, (ii) a decrease in transpiration rate, or (iii) enhanced adventitious root growth. It is well known that Bi can maintain water in itself and accordingly elevate the water accessible to plants within stress conditions [ 58 ]. Additionally, Bi application enhanced soil aggregate stability, decreased soil bulk density, increased soil surface area, and increased soil water-holding capacity, resulting in enhancing soil moisture retention efficiently [ 24 ].…”

Salinity is persistently a decisive feature confining agricultural sustainability and food security in arid and semi-arid regions. Biochar (Bi) has been advocated as a means of lessening climate changes by sequestering carbon, concurrently supplying energy and rising crop productivity under normal or stressful conditions. Melatonin (Mt) has been shown to mediate numerous biochemical pathways and play important roles in mitigating multi-stress factors. However, their integrated roles in mitigating salt toxicity remain largely inexpressible. A completely randomized design was conducted to realize the remediation potential of Bi and/or Mt in attenuation salinity injury on borage plants by evaluating its effects on growth, water status, osmotic adjustment, antioxidant capacity, ions, and finally the yield. Salinity stress significantly decreased the plant growth and attributed yield when compared with non-salinized control plants. The depression effect of salinity on borage productivity was associated with the reduction in photosynthetic pigment and ascorbic acid (AsA) concentrations, potassium (K+) percentage, K+-translocation, and potassium/sodium ratio as well as catalase (CAT) activity. Additionally, borage plants’ water status was disrupted by salinity through decreasing water content (WC), relative water content (RWC), and water retention capacity (WTC), as well as water potential (Ψw), osmotic potential (Ψs), and turgor potential (Ψp). Moreover, salinity stress evoked oxidative bursts via hyper-accumulation of hydrogen peroxide (H2O2) and malondialdehyde (MDA), as well as protein carbonyl, which is associated with membrane dysfunction. The oxidative burst was connected with the hyper-accumulation of sodium (Na+) and chloride (Cl−) in plant tissues, coupled with osmolytes’ accumulation and accelerating plants’ osmotic adjustment (OA) capacity. The addition of Bi and/or Mt had a positive effect in mitigating salinity on borage plants by reducing Cl−, Na+, and Na+-translocation, and oxidative biomarkers as well as Ψw, Ψs, and Ψp. Moreover, Bi and/or Mt addition to salt-affected plants increased plant growth and yield by improving plant water status and OA capacity associated with the activation of antioxidant capacity and osmolytes accumulation as well as increased photosynthetic pigments, K+, and K+/Na+ ratio. Considering these observations, Bi and/or Mt can be used as a promising approach for enhancing the productivity of salt-affected borage plants due to their roles in sustaining water relations, rising solutes synthesis, progressing OA, improving redox homeostasis, and antioxidant aptitude.

“…Therefore, Bio char (60:40) is the most optimum substrate based on drought resistance, closely followed by Coir (60:40) due to its ability to withstand pathogen attacks (Jacoby et al, 2017). It is also noteworthy to mention that previous study on Tritisivum aestivum (wheat) have also stated that Bio char is a strong resistor against drought conditions (Haider et al, 2020) which supports the result of this experimental study. Furthermore, Coir (60:40) is also identified in this study as a decent growing medium against drought based on the experiment conducted by the author.…”

Green roof of a building is partially or completely enfolded with vegetation and its associated components. It promotes the sustainability and comfort of buildings. This study determines the most suitable growing substrate by investigating organic wastes of Sawdust, Wood bark, Bio char, Coir, Compost and Base medium (fertilizer + potting mix) through comparing density, moisture content, drought resistance, thermal resistance, vegetation growth, pH, electric conductivity (EC) and nutrients. Unlike previous studies on green roof substrates, we have investigated chemical parameters and showed its importance on substrate selection. Unique mathematical concepts were used to find thermal conductivity and EC of specimens in our research. Preliminary study results shows that the most substrate composition includes 60% selected substrate and 40% base medium. Base medium (90:10) has highest bearing capacity to withstand external loads including vegetation and other imposed loads. Sawdust (60:40) exhibited consisted the least saturated unit weight, dry unit weight and the highest moisture content. In terms of drought resistance and vegetation growth, Bio char (60:40) was exceptional. Wood bark (60:40) exhibited the most convincing thermal resistance. The best characteristics in terms of pH, EC and nutrient content were exhibited by Sawdust (60:40), Coir (60:40) and Compost (60:40) correspondingly. Based on final ratings by considering all the experimental results, Coir (60:40) have emerged as the optimum growing medium in terms of physical and chemical properties. This experimental study results would provide a strong framework for construction industries to enhance sustainable green roof constructions with best practice in substrate selection.

The effect of arbuscular mycorrhizal fungi on the phenolic compounds profile, antioxidant activity and grain yields in wheat cultivars growing under hydric stress

et al. 2021

BACKGROUND: Hydric stress affects the production of wheat (Triticum aestivum L.) worldwide, making some tools necessary to cope with the decrease in rainfall. A sustainable alternative is the use of arbuscular mycorrhizal fungi (AMF) as biofertilisers.Here, we analysed the effects of AMF strains adapted or non-adapted to hyper-arid conditions on the phenolic profiles and antioxidant activities of wheat grains from two cultivars with contrasting tolerance to osmotic stress (Ilustre, moderately tolerant; and Maxi, tolerant) grown with and without hydric stress. RESULTS: Eight phenolic compounds were detected, apigenin-C-pentoside-C-hexoside I being the most abundant and showing an increase of 80.5% when inoculated with the fungus Funneliformis mosseae (FM) obtained from Atacama Desert under normal irrigation with respect to non-mycorrhizal (NM) plants. NM treatments were associated with higher grain yields. FM showed a noticeable effect on most phenolic compounds, with an increase up to 30.2% in apigenin-C-pentoside-C-hexoside III concentration under hydric stress with respect to normal irrigation, being also responsible for high antioxidant activities such as ABTS (2,2 0 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) activities.CONCLUSION: Inoculation with FM adapted to hydric stress produced improvements in phenolics composition and antioxidant activities in grains from wheat plants growing under hydric stress conditions, improving their food quality and supporting the development of further studies to determine whether the use of adapted AMF could be a realistic tool to improve grain quality in a scenario of increasing hydric stress conditions.
