Response of activated oxygen metabolism to water stress in different drought‐tolerant alfalfa(Medicago sativa)at seedling stage

摘要：

Plant growth and productivity are affected by various abiotic stresses such as heat,cold, drought and high salinity and so on.Water stress is considered to be the main environmental factor limiting plant growth and yield worldwide, especially in semi‐arid areas ( Boyer,1982 ).Alfalfa ( Medicago sativ a) is an important legume forage with high drought resistance.However, drought stress is still the main adverse factor limiting alfalfa production.The aim of the present study was to assess response of activated oxygen metabolism to water stress in different drought‐tolerant alfalfa at seedling stage in order to provide theoretical basis for drought‐tolerance alfalfa breeding.
