Salinity stress one of the fundamental problems in non-native cultures native plants and that reduces the growth. There are many components to minimize the negative effects of stress. One type of compound salicylic acid (SA) is a new group of endogenous growth regulators of natural phenolic compounds in plants can be considered and will play a defensive role against environmental stresses. In this context in order to study the interaction of salicylic acid and salinity on plant physiological characteristics melon, experiment was conducted in 2012 at the Zabol University research most were completely randomized design with three treatments salinity at three levels (0, 100 and 500 mg/kg) and salicylic acid at three levels (0.1 and 2 mM). Results showed increasing levels of salinity, chlorophyll a and b, carotenoids, leaf area index, leaf Aspd and cotyledons Aspd and primary leaves was significantly decreased compared to control, The decline was led a discount in front of the salicylic acid. According to the findings, the application of salicylic acid (2 mM) in saline conditions could partially reduce salt damage.
