ABSTRACT Salinity stress is one of the serious abiotic stress and lead to reduced productivity and plant growth. The effect of salinity stress and its interaction with ascorbic acid was investigated on some morphological traits. Ascorbate is a strong antioxidant which has remarkable biological effects on plants growth including an improvement in plants tolerance under salinity stress conditions. The purpose of this study was to determine the effect of ascorbic acid application to improve salt tolerance of rice on saline soil. This research was down as a factorial based on randomized block design with 3 replications. In this research were tested eight varieties of Rice Ciherang V1 IR 64 V2 Lambur V4 Batanghari V5 Banyuasin V6 IR 42 V8 Inpara 10 V9 and Margasari V10 and Ascorbic Acid is applied at concentrations of 0 A0 500 ppm A1 1000 ppm A2 and 1500 ppm A3. Ascorbic acid is applied in 4 times with at the age of 15 35 55 and 75 days after sowing. All concentrations of ascorbic acid generally has a positive effect on morphological characters. However the best response was found at 1500 ppm A3 concentration of ascorbic acid on Banyuasin variety.
