Abstract: Ethephon (2-chloroethyl phosphonic acid, an ethylene-releasing compound) is a plant growth regulator with various systemic properties. It is widely used on wheat, coffee, tobacco, cotton, and rice in order to help fruit to mature more quickly. Various effects of ethephon treatment on plants have been published. This article focused on reviewing the effects of foliar ethephon application on plant drought tolerance. To date, either promotion or inhibition of drought tolerance by ethephon treatment was reported. The effect of ethephon treatment on plant drought response was dependent on many factors, such as the concentrations of ethephon solution, plant species and cultivars, plant developmental stages, and treatment methods. In addition, the possible mechanisms of ethephon treatment affecting plant drought tolerance were discussed.
