Despite being trialed in other regions of the world, the use of molecular hydrogen (H) 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 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 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 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 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.
尽管分子氢（H）在世界其他地区已进行试验，但在英国，利用其促进植物生长和进行作物采后储存尚未得到广泛认可。用H处理植物和植物产品可缓解植物胁迫并延缓作物衰老，这方面的证据不断增加。其中许多效应似乎是由植物细胞抗氧化能力的改变介导的。有些效应似乎涉及血红素加氧酶，同时也有人提出辅基Fe的减少是一种机制。尽管在田间环境中难以作为气体处理使用，但富氢水（HRW）有可能给农业实践带来显著益处。然而，只有当益处超过生产和应用成本时，农业中才会采用H。HRW安全且相对易于使用。如果其他国家将H气体或HRW用于农业目的，那么很有可能在未来英国也能广泛使用，特别是用于采后储存，从而减少食物浪费。
