The Explants that was used in the experiment to stimulate the production of glycoside compounds is the tips of the vegetative branches with a length of 2 cm obtained from the stage of vegetative multiplication growing from seeds treated with gamma radiation with a dose of (0, 30) gray, the tips of the branches were planted on MS nutrient medium prepared with different concentrations Of NaCl (3,0, 6, 9, 12) g.l-1 to know the effect of irradiation, sucrose and maltose in stimulating the production of cardiac glycoside compounds, chlorophyll and carbohydrates, the data showed that the concentration of 12 g.l-1 was better in increasing the active compounds: Digoxin, Digitoxin, and Gitoxin (129.46, 171.70, 145.59) μg.g-1 dry weight, respectively, while the neutral treatment was superior in increasing the rate of chlorophyll, which amounted to 2.10 µg.g-1, while the concentration of 3 g.l-1 gave the highest rate of carbohydrates amounting to 2.94 µg.g-1, and the irradiation treatment was significantly superior in The increase in the production of glycoside compounds reached (127.95, 193.95, 161.31) µg.g-1 dry weight, respectively, and the rate of chlorophyll and carbohydrates reached (2.38 and 3.11) µg.g-1, respectively.
