“…Compared to solid H 2 storage materials such as MgH 2 , AB, and other nanoparticles, HNW will not bring additional elements. Recently, genetic and molecular evidence showed that molecular hydrogen not only influenced root organogenesis [63,64], but also increased nitrogen use efficiency (NUE) by targeting nitrate reductase [65]. Consistently, in this report, we revealed that the preharvest application of hydrogen fertilization with HNW exhibited a fertilization effect on the cherry tomato yield and improved its quality, even to some extent as an alternative for the conventional fertilizers.…”

Although hydrogen gas (H2)-treated soil improves crop biomass, this approach appears difficult for field application due to the flammability of H2 gas. In this report, we investigated whether and how H2 applied in hydrogen nanobubble water (HNW) improves the yield and quality of cherry tomato (Lycopersicon esculentum var. cerasiforme) with and without fertilizers. Two-year-long field trials showed that compared to corresponding controls, HNW without and with fertilizers improved the cherry tomato yield per plant by 39.7% and 26.5% in 2021 (Shanghai), respectively, and by 39.4% and 28.2% in 2023 (Nanjing), respectively. Compared to surface water (SW), HNW increased the soil available nitrogen (N), phosphorus (P), and potassium (K) consumption regardless of fertilizer application, which may be attributed to the increased NPK transport-related genes in roots (LeAMT2, LePT2, LePT5, and SlHKT1,1). Furthermore, HNW-irrigated cherry tomatoes displayed a higher sugar–acid ratio (8.6%) and lycopene content (22.3%) than SW-irrigated plants without fertilizers. Importantly, the beneficial effects of HNW without fertilizers on the yield per plant (9.1%), sugar–acid ratio (31.1%), and volatiles (20.0%) and lycopene contents (54.3%) were stronger than those achieved using fertilizers alone. In short, this study clearly indicated that HNW-supplied H2 not only exhibited a fertilization effect on enhancing the tomato yield, but also improved the fruit’s quality with a lower carbon footprint.

Hydrogen−rich water (HRW) is widely recognized for its growth promoting, antioxidant, and anti−inflammatory properties. However, little is known about the role of HRW in aquaculture. This study aims to investigate how different concentrations of HRW affect the growth performance, digestive ability, antioxidant capacity, mTOR signaling pathway, and gut microbiota of juvenile largemouth bass. We randomly assigned 360 fish (13.73 ± 0.1 g) to three treatments. The control group was maintained in regular water, while the treatment groups were treated with different concentrations of H2 dissolved in water, which were H1 (179.65 ± 31.95 ppb) and H2 (280.65 ± 64.43 ppb), respectively. Through an analysis of the three treatments, it was found that H1 significantly increased the final body weight, weight gain rate, specific growth rate, and survival rate, and reduced the feed conversion ratio (p < 0.05). In addition, the trypsin activity was significantly increased in the intestine (p < 0.05), and the expression of genes related to the glucose metabolism (pk and pepck) and mTOR (tor, akt, s6k1, 4ebp1, and ampka) signaling pathways were significantly increased in the liver in H1 (p < 0.05). The relative abundance of Blautia in the gut microbiota (p < 0.05) was significantly increased in H1. Therefore, these results indicated that H1 can significantly improve growth performance, promote intestinal digestion, activate the glucose metabolism pathway and mTOR signaling pathway, and increase the abundance of beneficial bacteria in the gut of largemouth bass. These findings provided valuable support for the application of HRW to support the healthy aquaculture of largemouth bass.

A key element in the effective recovery of plants after drought is slowing down of their senescence accelerated during the drought. Therefore, in this paper the relationships between hydrogen peroxide content and effective recovery during rehydration after water stress were analyzed. The study focused on two DH lines of winter triticale with different regeneration potential, as shown by different numbers of lateral stems with ears, grown during rehydration after water stress. During rehydration, the GZDH27 line grows two to three lateral stems with ears, whereas the GZDH88 line grows a single lateral stem with ear. The two DH lines of winter triticale showed comparable responses to the drought stress but their responses to rehydration after the drought stress were clearly different. Results revealed, that the increased accumulation of hydrogen peroxide, which was induced during the drought, can be maintained during rehydration, thus stimulating plant senescence. In the line GZDH88, rehydration did not slow down drought-induced senescence. This was manifested by higher levels of hydrogen peroxide, accompanied by lower levels of chlorophyll in the flag leaves of GZDH88 plants, as the result of which only one lateral stem was formed during rehydration. However, development of one lateral stems during rehydration in the GZDH88 line allowed for smaller yield loss than in the GZDH77 line, that developed of three lateral stems during rehydration. The efficient production of carbohydrates and their effective allocation into the ears of the lateral stems required considerable energy expenditure in the GZDH27 line. Our results indicate that growing three lateral stems with ears during rehydration does not guarantee limitation of grain yield loss. However, to reach the final conclusion, it is important to evaluate a greater number of triticale genotypes under drought stress and rehydration during various stages of a plants development.
