The use of biological fertilizers in order to reduce the effects of environmental stress in plants is of particular importance. The present research was conducted to investigate the effect of seaweed extract on growth, physiological and biochemical properties of Pelargonium under salt stress. Salinity stress at three levels (0, 60 and 120 mM) with algae extract (0, 0.5, 1 and 2 g/L); It was done factorially based on a completely randomized design in three replications. The results showed that the salinity stress of 120 mM caused a significant decrease in the morphological characteristics of the plant (wet and dry weight of shoots and roots), the amount of photosynthetic pigments (chlorophyll a, b and total) of the plant, the use of algae extract caused The effect of salinity stress was reduced in the Pelargonium. In the salinity stress of 120 mM and without the use of algae extract, the highest amount of soluble carbohydrate synthesis (36.69%) and proline (37.63%) was compared to the control. The general results of the research showed that the Pelargonium was somewhat more resistant to mild salinity stress than to severe salinity stress, and the algae extract plays an important role in modulating the negative effect of salinity stress by increasing the growth and production of metabolic compounds of the Pelargonium
