“…Under stressful conditions such as the presence of excessive metal ions, hydrogen-rich water (HRW) has been shown to promote root growth 23 . The relief of stress by H 2 is believed to involve phytohormone signalling, as suggested by some studies 22 , 24 . Sun et al 25 assert that H 2 is safe for human consumption and, as a result, is safe to use in plant treatments for food crops.…”

“…Plants or plant tissues can receive H 2 as either a gas or a dissolved solution, which is typically created by bubbling H 2 through water to create hydrogen-rich water (HRW). HRW can be administered to plants by either adding it to the soil or feed solution or by spraying it onto the foliage 22 . Under stressful conditions such as the presence of excessive metal ions, hydrogen-rich water (HRW) has been shown to promote root growth 23 .…”

In the modern world, wheat, a vital global cereal and the second most consumed, is vulnerable to climate change impacts. These include erratic rainfall and extreme temperatures, endangering global food security. Research on hydrogen-rich water (HRW) has gained momentum in plant and agricultural sciences due to its diverse functions. This study examined the effects of different HRW treatment durations on wheat, revealing that the 4-h treatment had the highest germination rate, enhancing potential, vigor, and germination indexes. This treatment also boosted relative water content, root and shoot weight, and average lengths. Moreover, the 4-h HRW treatment resulted in the highest chlorophyll and soluble protein concentrations in seeds while reducing cell death. The 4-h and 5-h HRW treatments significantly increased H2O2 levels, with the highest NO detected in both root and shoot after 4-h HRW exposure. Additionally, HRW-treated seeds exhibited increased Zn and Fe concentrations, along with antioxidant enzyme activities (CAT, SOD, APX) in roots and shoots. These findings suggest that HRW treatment could enhance wheat seed germination, growth, and nutrient absorption, thereby increasing agricultural productivity. Molecular analysis indicated significant upregulation of the Dreb1 gene with a 4-h HRW treatment. Thus, it shows promise in addressing climate change effects on wheat production. Therefore, HRW treatment could be a hopeful strategy for enhancing wheat plant drought tolerance, requiring further investigation (field experiments) to validate its impact on plant growth and drought stress mitigation.

“…Antioxidants neutralise reactive oxygen and reactive nitrogen species (ROS/RNS, respectively), which can cause oxidative stress and damage to cells and tissues and disrupt essential functional physiological processes, including energy metabolism and the biosynthesis of proteins and peptides [10]. As an antioxidant, H 2 is demonstrated to quench cytotoxic free radicals, enhance endogenous antioxidant capacity and modulate both inflammatory responses (in animals) [11,12] and stress responses (in animals and in plants) [11,13]. Oxidation of biomolecules can also be inhibited with the post-harvest treatment of plant products (e.g., exposure to H 2 gas or treatment with hydrogen-rich water (HRW)).…”

Molecular hydrogen (H2) is a low-molecular-weight, non-polar and electrochemically neutral substance that acts as an effective antioxidant and cytoprotective agent, with research into the effects of H2 incorporation into the food chain, at various stages, rapidly gaining momentum. H2 can be delivered throughout the food growth, production, delivery and storage systems in numerous ways, including as a gas, as hydrogen-rich water (HRW), or with hydrogen-donating food supplements such as calcium (Ca) or magnesium (Mg). In plants, H2 can be exploited as a seed-priming agent, during seed germination and planting, during the latter stages of plant development and reproduction, as a post-harvest treatment and as a food additive. Adding H2 during plant growth and developmental stages is noted to improve the yield and quality of plant produce, through modulating antioxidant pathways and stimulating tolerance to such environmental stress factors as drought stress, enhanced tolerance to herbicides (paraquat), and increased salinity and metal toxicity. The benefits of pre- and post-harvest application of H2 include reductions in natural senescence and microbial spoilage, which contribute to extending the shelf-life of animal products, fruits, grains and vegetables. This review collates empirical findings pertaining to the use of H2 in the agri-food industry and evaluates the potential impact of this emerging technology.
