This study was conducted in the Nursery of the Forestry Department of the College of Agriculture and Forestry, University of Mosul on the seeds of Ceratonia siliqua L. pre-treating their seeds with concentrated sulfuric acid 98% for different periods (0, 5, 10 and 15 minutes) and then exposing them to electric shock for different periods also (0, 3 and 6 minutes). Some physiological characteristics chlorophyll (a) and (b), total chlorophyll, proteins, and percentage of nitrogen, phosphorous and potassium were studied. The results showed the superiority of immersion treatment in sulfuric acid (15) minutes for the percentage of total proteins, nitrogen and potassium elements and treatment for 10 minutes gave the highest rate of total phosphorous compared with the control. The treatment with 5 minutes gave the highest rate of chlorophyll (a and b) compared with the control treatment. As for the effect of electric shock, treatment with 6 minutes recorded the highest rates for the percentage of total proteins, nitrogen, potassium and chlorophyll (a and b), while treatment with 3 minutes gave the highest rate of phosphorous compared with the control treatment. As for the interaction effect for both factors, treatment (5 minute of H2SO4 x 6 minute of electrical shock) recorded the highest rates for the leaves content of chlorophyll (b) and total chlorophyll, and the interaction treatment (15x6) gave the highest rates of protein and for nitrogen and potassium %, except for phosphorous in the leves, the highest rates were recorded with (15x3) treatment.
