Abstract

NaCl salinity stress is one of the most important factors that limits the production of agricultural products. In order to study the effect of using salicylic acid on morphological and biochemical properties of Oryza sativa L. (Neda cultivar) under NaCl salt stress, a factorial experiment was performed in a completely randomized block design with 3 replications. The seedlings were treated with sodium chloride (0, 25, 50, 75 and 100 mM) and salicylic acid (0, 0.5 and 1 mM). The results showed that salicylic acid significantly (P <0.05) reduced morphological traits (germination percentage, plumule and radicle length) under stress conditions and reduced the side effects of salinity on the plants. Also, with increasing concentration of NaCl, proline and malondialdehyde contents and antioxidant activity increased, while adding salicylic acid to the culture medium of plants under NaCl salinity malondialdehyde content reduced and the growth parameters increased. In plants with seeds pre-treated with salicylic acid with increasing proline content, antioxidant activity reduced the side effects of NaCl salinity stress on rice.
