Molecular hydrogen in agriculture

Planta volume 254, Article number: 56 (2021) Cite this article

Abstract

Main conclusion

H2 gas, usually in the form of H2-saturated water, could play a useful role in improving many aspects of plant growth and productivity, including resistance to stress tolerance and improved post-harvest durability. Therefore, molecular hydrogen delivery systems should be considered as a valuable addition within agricultural practice.

Abstract

Agriculture and food security are both impacted by plant stresses, whether that is directly from human impact or through climate change. A continuously increasing human population and rising food consumption means that there is need to search for agriculturally useful and environment friendly strategies to ensure future food security. Molecular hydrogen (H2) research has gained momentum in plant and agricultural science owing to its multifaceted and diverse roles in plants. H2 application can mitigate against a range of stresses, including salinity, heavy metals and drought. Therefore, knowing how endogenous, or exogenously applied, H2 enhances the growth and tolerance against numerous plant stresses will enhance our understanding of how H2 may be useful for future to agriculture and horticulture. In this review, recent progress and future implication of H2 in agriculture is highlighted, focusing on how H2 impacts on plant cell function and how it can be applied for better plant performance. Although the exact molecular action of H2 in plants remains elusive, this safe and easy to apply treatment should have a future in agricultural practice.
