分子状水素による切り花の日持ち延長への応用可能性：課題と展望
This review examines the potential of molecular hydrogen (H2) in agricultural postharvest management, with a focus on floral senescence and vase life extension. H2 possesses antioxidant, anti-inflammatory, apoptosis-suppressing, and hormone-regulating properties that have been explored in both biomedical and agricultural contexts. While H2 application for delaying postharvest ripening in fruits is relatively established, research specifically addressing flower senescence—both at preharvest and postharvest stages—remains sparse. The review outlines current tools and approaches that may improve floral preservation and storage quality, while also discussing the advantages and limitations associated with H2 use in floriculture. The relevance of H2 to COVID-19 management is briefly noted in the context of its broader biological properties.
H2 is proposed to selectively scavenge reactive oxygen species and modulate inflammatory signaling, apoptosis, and hormone regulation, collectively delaying senescence processes in plant tissues.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
