To study the effect of salinity on photosynthesis pigments, fluorescence and antioxidants of three varieties of peanut leaf as an indicator of resistance to salinity, research was carried out as factorial arrangement based on completely randomized design with three replications in the greenhouse of University of Guilan in 2013. The experiment consisted of a combination of 4 different salinity levels (0, 50, 100 and 150 mM) and three cultivars of peanut (Local Guilan, ICGV96177 and ICGV03060). The results showed that the interaction between cultivars and salinity measurement on characteristics of chlorophyll a, chlorophyll a + b the maximum fluorescence (Fm) initial fluorescence (F0), Peroxidase and phenol were significant except for carotenoids. This study indicated that increasing the concentrations of NaCl, Phenol and peroxidase increased the amount of chlorophyll a and b, and chlorophyll fluorescence yield decreased, and in general the local cultivar of Guilan was the most resistant one under different levels of salinity.
