摘　　要：氢气(hydrogen,H_2)是已知最轻的双原子气体分子,作为一种重要的信号分子,参与了植物生长发育的调节和植物逆境的修复,引起了人们的广泛关注。本文就富氢水对植物的生长效应,及其在芽苗菜栽培中的应用前景进行了综述。在环境胁迫(盐胁迫、重金属胁迫、农药胁迫)下,H_2通过提高植物体内抗氧化酶活性来清除过量的ROS、调节内源NO和激素水平从而缓解胁迫对植物造成的损伤;H_2可以通过提高芽苗菜的次生代谢产物和抗坏血酸含量来提高其营养品质。Hydrogen （H2）, known as the lightest diatomic gas molecule, is an important signal one. It is involved in the regulation of plant growth and development, and repairing of plant adversity, thus has attracted widespread attention of the people. This paper reviews the effects of hydrogen gas on plant growth, and its application prospect in sprout seedling cultivation. Hydrogen gas removes excess ROS by increasing the activity of antioxidant enzymes, and regulating endogenous NO and hormone levels to relieve the injury under the environmental stress （ salt stress, pesticide stress, heavy metal stress ） . Hydrogen gas can improve the level of secondary metabolites and ascorbic acid content of Sprout seedling to improve its nutritional quality.
