| Sumario: | Despite being trialed in other regions of the world, the use of molecular hydrogen (H<sub>2</sub>) for enhanced plant growth and the postharvest storage of crops has yet to be widely accepted in the UK. The evidence that the treatment of plants and plant products with H<sub>2</sub> alleviates plant stress and slows crop senescence continues to grow. Many of these effects appear to be mediated by the alteration of the antioxidant capacity of plant cells. Some effects seem to involve heme oxygenase, whilst the reduction in the prosthetic group Fe<sup>3+</sup> is also suggested as a mechanism. Although it is difficult to use as a gaseous treatment in a field setting, the use of hydrogen-rich water (HRW) has the potential to be of significant benefit to agricultural practices. However, the use of H<sub>2</sub> in agriculture will only be adopted if the benefits outweigh the production and application costs. HRW is safe and relatively easy to use. If H<sub>2</sub> gas or HRW are utilized in other countries for agricultural purposes, it is tempting to suggest that they could also be widely used in the UK in the future, particularly for postharvest storage, thus reducing food waste. |
