H2HUBB TAKEAWAY
Antioxidant concentrations of lycopene, ascorbic acid, flavonoids, and resveratrol in hydrogen nanobubble water drip-irrigated tomato fruits increased by 16.3-264.8% and 2.2-19.8%, respectively, compared to underground water and oxygen nanobubble water. This source-grounded publication contributes evidence relevant to molecular hydrogen and is retained in a transparent general research category when a more specific study design is not supported by the indexed record.
What the Findings Mean
H2HUBB reviewed how molecular hydrogen was evaluated in this publication and summarizes the source-grounded findings below. Antioxidant concentrations of lycopene, ascorbic acid, flavonoids, and resveratrol in hydrogen nanobubble water drip-irrigated tomato fruits increased by 16.3-264.8% and 2.2-19.8%, respectively, compared to underground water and oxygen nanobubble water.
What the Researchers Studied
The comparison condition was control condition or baseline measurements.
What Effects Did Molecular Hydrogen Have?
The volume and purity (>99.99%) of hydrogen and oxygen used to produce the nanobubbles were the same. The hydrogen gas was bubbled into 10 L underground water at a rate of 3 Nl/min for 20 min. Antioxidant concentrations of lycopene, ascorbic acid, flavonoids, and resveratrol in hydrogen nanobubble water drip-irrigated tomato fruits increased by 16.3-264.8% and 2.2-19.8%, respectively, compared to underground water and oxygen nanobubble water. The authors concluded that this is the first study to report that HNB subsurface drip irrigation of tomatoes significantly affects fruit natural antioxidant qualities. However, the physiological adaptation and response mechanism of crops to hydrogen nanobubbles is still poorly understood. Considering the characteristics of hydrogen and the application of the nanobubble technology in agriculture, the findings of the present study could facilitate the understanding of the potential effects of hydrogen on biological processes and the mechanisms of action on plant growth and development.
