“…As in our study, drought can negatively affect mycorrhizal colonization in quinoa [ 56 , 81 ]. Similarly, previous studies revealed that root colonization by AMF and hyphal growth declined under water limitation stress [ 44 , 82 , 83 ]. The soil water status significantly affects germination and/or spore development [ 84 , 85 ].…”

The present study aimed to determine the effects of biostimulants on the physicochemical parameters of the agricultural soil of quinoa under two water regimes and to understand the mode of action of the biostimulants on quinoa for drought adaptation. We investigated the impact of two doses of vermicompost (5 and 10 t/ha) and arbuscular mycorrhizal fungi applied individually, or in joint application, on attenuating the negative impacts of water shortage and improving the agro-physiological and biochemical traits of quinoa, as well as soil fertility, under two water regimes (well-watered and drought stress) in open field conditions. Exposure to drought decreased biomass, leaf water potential, and stomatal conductance, and increased malondialdehyde and hydrogen peroxide content. Mycorrhiza and/or vermicompost promoted plant growth by activating photosynthesis machinery and nutrient assimilation, leading to increased total soluble sugars, proteins, and antioxidant enzyme activities in the leaf and root. After the experiment, the soil’s total organic matter, phosphorus, nitrogen, calcium, and soil glomalin content improved by the single or combined application of mycorrhiza and vermicompost. This knowledge suggests that the combination of mycorrhiza and vermicompost regulates the physiological and biochemical processes employed by quinoa in coping with drought and improves the understanding of soil–plant interaction.

“…The hydrogel led to a decreased diameter for the largest flower of G. rigens, decreased flowering of P. peltatum, and negatively affected P. zonale plants. It was concluded that the inclusion of hydrogel in the potting medium had no positive effects on any of the parameters of the three tested species of plants, as shown in Table 3 [117]. The hydrogel underperformance could be due to several reasons.…”

Hydrogel Application in Urban Farming: Potentials and Limitations—A Review

et al. 2022

Urban agriculture plays a vital role in ensuring the self-sufficiency of a great variety of fresh vegetables and nutrients. It promotes a sustainable food system as well as reducing the dependency on imports for the growing population. Urban farming has made it possible for agriculture practices to be implemented anywhere at any time in a sophisticated way. Hydrogel has been introduced in urban agriculture in the past few decades. However, the application of hydrogel in urban agriculture is still being explored in terms of hydrogel types, structure, physical and chemical properties, change due to external factors, and its suitability for different plant species. This review discusses the potentials and limitations of hydrogel in different application conditions. We present the state of knowledge on hydrogel production and crosslinking methods, hydrogel characteristics, water absorption and release mechanisms of hydrogel, hydrogel advantages and limitations, and current and future applications in urban farming.

“…Nevertheless, despite the intrinsic plant defence mechanisms, it is necessary to identify new strategies that plants can use to cope with drought, allowing plant growth. In this context, the associations between plants and arbuscular mycorrhizal fungi (AMF) are of great importance because AMF increases a plant's resistance to water shortages 16‐19 . In particular, several studies have shown that, in a large number of plants forming AMF, their tolerance to drought improves through various mechanisms, such as (i) increases in water uptake as a result of penetration of hyphae into very small pores inaccessible to roots and AMF mycelium contributions to water redistribution through the soil 19 ; (ii) the influence on modulation of aquaporin expression 20‐22 ; (iii) improvements in the photosynthetic efficiency 23,24 ; (iv) increases in plant nutrient uptake 15,16 ; and (v) enhancements in antioxidant enzyme activity 25‐26 .…”

BACKGROUND A decrease in rainfall is one of the main constraints on wheat production, although the association of wheat with arbuscular mycorrhizal fungi (AMF) may be an alternative for crop production under drought conditions. In the present study, we used three wheat cultivars (Purple, Ilustre and Maxi Baer) inoculated with two AMF strains, one obtained from the hyperarid Atacama Desert (northern Chile; Fm) and the other obtained from southern Chile (Cc). Plants were maintained under two irrigation conditions (normal irrigation and drought) and the physiological behaviour and enzymatic and nonenzymatic antioxidant activities in the shoots were determined. In addition, the phenolic compounds were identified by high‐performance liquid chromatography‐dioide array detection‐electrospray ionization‐tandem mass spectrometry and quantified. RESULTS AMF colonization produced higher levels of efficiency of photosystem II and photosynthetic pigments. High values of catalase in Purple‐Cc, ascorbate peroxidase in Purple‐Cc, glutathione reductase in Maxi‐Cc and superoxide dismutase in Purple‐Cc, all under stress, were registered. Of the inoculated cultivars, Purple‐Cc showed the highest flavonoid levels, whereas hydroxycinnamic acids were higher in Maxi‐Fm without drought, with apigenin and luteolin being the most abundant. High levels of phenols were present in the Ilustre‐Fm plants without drought. Under normal irrigation, high levels of antioxidant activity were registered in the AMF treatments, whereas, under stress conditions, in general, high values were observed under the Fm inoculation. CONCLUSION Our results showed that the greatest antioxidant activity and phenolic content occurred in wheat plants inoculated with AMF, indicating their influence on coping with water stress, which is of importance in vast areas where global climate change is resulting in diminished rainfall. © 2021 Society of Chemical Industry.
