Abstract
In the most regions of the world, salinity stress is the most important stress that limits the growth of plants and its performance by decreasing the osmotic potential and disrupting the absorption of water and some nutrients. Salicornia Persica, is a halophyte and annual plant and resistant to the salinity. Ascorbic acid can increase resistance of plant than stress through stimulating the activity of antioxidant enzymes. An experiment was carried out in2019 in the research greenhouse of Malayer University in a factorial format in a completely randomized design, in order to evaluate the effect of different concentrations of ascorbic acid (0, 0. 2mm) on the morphological characteristics of Salicornia Persica, under the conditions of salinity stress (0,300, and 600ppm). The results showed that salinity stress caused a significant increase in the dry weight of aerial parts. On the other hand, spraying with ascorbic acid caused an increase in the dry weight of aerial parts. Salinity caused a reduction in the amount of photosynthetic pigments. The amount of Proline increased at 300ppm salinity and decreased at 600ppm salinity. Generally, It can be concluded that spraying of Salicornia Persica with ascorbic acid improved the growth and the tolerance of this plant against the effects of salinity
