EFFECT OF SALINITY AND SALICYLIC ACID ON SOME VEGETATIVE GROWTH CHARACTERISTICS AND CHEMICAL CONTENT OF FICUS CARICA L. SEEDLINGS

Abstract

The experiment was carried out with the aim of determining the effect of salicylic acid at concentrations (0,50,100) mg/L on fig seedlings exposed to salt stress through treatment with concentrations (0,50,100,150) mmol/L of sodium chloride salt. A significant decrease in some growth characteristics (seedling height and stem diameter) was noted from the results with increasing concentrations of salicylic acid. However, treatment with concentrations of salicylic acid led to improved seedling growth, especially when treated with 100 mg/L. The results showed a decrease in the level of dry matter and total chlorophyll. And carbohydrates with an increase in salinity concentrations. Treatment with salicylic acid led to an increase in the level, and the highest levels were reached when spraying with a concentration of 100 mg/L of salicylic acid. As for the concentration of proline, it increased with an increase in salinity concentrations, but it decreased when sprayed with salicylic acid with a concentration of 100 mmol/L.
