Salicylic acid is an important endogenous signal molecule in inducing plant's resistance to biotic stress. It can enhance the resistance of plants against environmental stresses, such as cold, heat, salt, drought, zone and heavy metals. Studies of SA on the many environmental stresses were reviewed and its mechanism was explored in this paper.
