氢气对植物生理功能的影响及作用机制研究进展

氢气(H_2)作为一种新型抗氧化剂广泛用于临床治疗中且疗效良好。植物体内可产生H_2,且在生长发育和胁迫应答等过程中发挥重要作用。综述了内源性H2在植物中的产生以及外源H_2处理对植物的生长发育、抗逆性、根际微生物和采后保鲜等的影响及其作用机制,并进一步探讨了H_2与其他植物激素和内源性小分子气体的交叉作用,为H_2在植物生理作用中的深入研究和应用奠定理论基础。

Research Progress on Effects of Hydrogen on Plant Physiological Roles and Its Mechanism

Hydrogen( H2 ) ,as a new type of antioxidant,has been widely used in many clinical treatments, and has achieved ideal therapeutic effect. H2 can be produced in plants and play an important role in plant growth and stress response. This article reviewed the production of endogenous H2 in plants,regulation of H2 on plant growth and development,resistance,rhizosphere microorganisms and postharvest preservation and possible mechanisms.The interaction between H2 and other plant endogenous gas molecules and plant hormones was analyzed.These studies provided theoretical basis for the further study of H2 in plants.
