“…Seeds of L. stoechas displayed a wide viability range, 89.2% germination at non-stress condition, with a characteristic nondeep dormancy; however, as supposed, salinity induced resulted in a corresponding decrease in seed germination. Such results in germination reduction have been reported by using either NaCl only, as in Retama raetam (Mehdadi et al, 2017) and P. pallida (Aljasmi et al, 2021), or various single soluble salts, as in Artemisia herba-alba (Nedjimi, Zemmiri, 2019) and Marrubium vulgare (Nedjimi et al, 2020).…”

“…Wild plants, meanwhile, deploy a number of adaptive mechanisms to cope with aridity. Postponing germination till the arrival of adequate conditions, including sufficient rainfall, is one such mechanism (Aljasmi et al, 2021). Till date, little is known about seed germination performance and plant growth response against drought, particularly in the North African natural flora (Dadach, Mehdadi, 2021).…”

“…Till date, little is known about seed germination performance and plant growth response against drought, particularly in the North African natural flora (Dadach, Mehdadi, 2021). Understanding the level of moisture stimulating germination and species-specific threshold tolerance to water stress is the cornerstone towards achieving sustainable plant reintroduction and land restoration projects in degraded habitats (De Carvalho et al, 2020;Aljasmi et al, 2021). Lavandula stoechas (Lamiaceae) is a well-known multipurpose plant that is often used throughout the Mediterranean region in traditional medicine, perfumes and other personal care products or sold as an ornamental plant for gardening (Ernst, 2017).…”

Information relating to germination and seedling emergence of a plant aids in determining the species spatiotemporal distribution and also facilitates in designing appropriate plant management strategies within an ecosystem. Lavandula stoechas L. (Lamiaceae), a naturally occurring shrub, is particularly used in pharmaceutical and cosmetic industries. This species, indeed, has the potential for rehabilitation of degraded costal lands. However, various aspects of its seed biology have not yet been recognised. Here, we aimed to assess the effects of different soluble salts (NaCl, CaCl2, MgCl2 and Na2SO4) and drought (as simulated by polyethylene glycol, [PEG]6000) on seed germination patterns and early seedling growth responses. Seeds treated with five iso-concentration (0–100 mM) salinities and five PEG6000 (0 to −1 MPa) levels were incubated in a controlled germinator set at 20°C. The preliminary results revealed that seeds of L. stoechas lacked primary/innate dormancy and they germinated abundantly (89.2% germination) and fast (7.4% day−1) in the absence of stress. Regardless of the kind of salt applied, the germination percentage (GP) and germination rate index (GRI) fell significantly with increasing salinity, and germination ceased completely at 100 mM Na2SO4. In fact, the salinity tolerance index (STI) showed that, among all salts tested, Na2SO4 appeared to have more inhibitory action on germination. In addition, L. stoechas was found to be tolerant to moderate salty stress (<50 mM) in early growth phase. The salt solution parameters (i.e. concentration, electrical conductivity [EC] and salt content) were best correlated with seed/seedling metrics. pH was not a good predictor for salt effects at the germination/seedling stages. Overall, this species seems to be sensitive to drought at the germination and initial growth phases. The germination recovery potential of L. stoechas in both stresses stipulates that this species can be regarded as a promising candidate in the rehabilitation of Mediterranean disturbed coastal habitats.

“…In addition, the application of cyanobacteria extracts significantly increased the average germination of Lupinus termis seeds treated with different growth regulators, such as indole acetic acid, gibberellic acid, and cytokinins seeds, compared to controls. In addition, rice seeds treated with four species of Anabaena, a genus of cyanobacteria, significantly increased the rice seeds' final germination and germination rate [79]. Refining the fertility of saline soils is critical from an agricultural perspective.…”

The excessive use of agrochemicals to ensure food security under the conditions of a growing population, global climate change, weather extremes, droughts, wasteful use of freshwater resources, and land degradation has created severe challenges for sustainable crop production. Since the frequent and abrupt environmental changes are outcompeting the existing agricultural technologies of crop production systems to meet food security, the development and use of modern technologies and nature-based solutions are urgently needed. Nanotechnology has shown potential for revolutionizing agri-production and agri-business in terms of nanofertilizers and nanoparticles for crop protection. Furthermore, in the recent past, biochar has been identified as a negative emission technology for carbon sequestration and soil fertility improvement. However, supply chain issues for biochar, due to feedstock availability, challenges its worldwide use and acceptability. Meanwhile progress in algae research has indicated that, algae can be utilized for various agro-ecosystem services. Algae are considered an efficient biological species for producing biomass and phytochemicals because of their high photosynthetic efficiency and growth rate compared to terrestrial plants. In this context, various options for using algae as a nature-based solution have been investigated in this review; for instance, the possibilities of producing bulk algal biomass and algal-based biofertilizers and their role in nutrient availability and abiotic stress resistance in plants. The potential of algae for biochar production (hereafter “phycochar” because of algal feedstock), its elemental composition, and role in bioremediation is discussed. The potential role of agal nanoparticles’ in mitigating abiotic stress in crop plants was thoroughly investigated. This review has effectively investigated the existing literature and improved our understanding that, algae-based agro-solutions have huge potential for mitigating abiotic stresses and improving overall agricultural sustainability. However, a few challenges, such as microalgae production on a large scale and the green synthesis of nanoparticle methodologies, still need further mechanistic investigation.

“…Previous studies have demonstrated the capacity of Prosopis seeds to germinate under NaCl concentrations up to 600 mM [ 34 , 38 ], suggesting that Prosopis species can establish in relatively high saline soils. Similarly, Sohrabi and Gherekhloo (2012) [ 39 ] and Aljasmi et al [ 40 ] found that Prosopis species could germinate under osmotic stress equivalent to −1.0 MPa, suggesting that Prosopis species could also establish in dry environments. In addition to the capacity of the seeds to germinate in adverse conditions, it has been shown that Prosopis seedlings can successfully establish and grow in saline substrates [ 41 ] and tolerate long periods of water deprivation [ 31 ], suggesting that factors other than abiotic stress could be impairing seedling establishment success.…”

Prosopis chilensis and Prosopis tamarugo, two woody legumes adapted to the arid regions of Chile, have a declining distribution due to the lack of new seedling establishment. This study investigated the potential of both species to establish in soil collected from four locations in Chile, within and outside the species distribution, and to assess the role of the root-colonizing microbiome in seedling establishment and growth. Seedling survival, height, and water potential were measured to assess establishment success and growth. 16S and ITS2 amplicon sequencing was used to characterize the composition of microbial communities from the different soils and to assess the ability of both Prosopis species to recruit bacteria and fungi from the different soils. Both species were established on three of the four soils. P. tamarugo seedlings showed significantly higher survival in foreign soils and maintained significantly higher water potential in Mediterranean soils. Amplicon sequencing showed that the four soils harbored distinct microbial communities. Root-associated microbial composition indicated that P. chilensis preferentially recruited mycorrhizal fungal partners while P. tamarugo recruited abundant bacteria with known salt-protective functions. Our results suggest that a combination of edaphic properties and microbial soil legacy are potential factors mediating the Prosopis establishment success in different soils.
