Abstract
In order to studying the effect of soil salinity on physiological characteristics of Cotton genotypes this experiment was conducted in 1386 with potted cottons in phytotron condition and carried out as factorial in completely randomized design with 4 replications. One factor was Cotton cultivars and the other was levels of salinity at rate of 0.6, 7.6, 15.2 and 29.9ds/m. The results showed that the effect of salinity on physiological characteristics of Cotton plant such as anthocynanine, proline and glycinebetain were significant at 1% probability within cultivars. There were significant diffrences at 5% probability in relation to praline and glycinebetain. No significant difference was found between cultivars in regard to anthocyanine. By increasing the salinity in the soil the amount of anthocyanine, proline and glycine betain increased in Cotton plant.
