The influences of carbon sources, sucrose, glucose, fructose, mannitol and sorbitol on multiplication and rooting medium of strawberry Elsanta cv. were compared at of relatively wide range of concentrations (10-90 g ɭ-¹). There was a clear effect of seeds of sugar type and concentrations on the shoot multiplication rate. For each sugar added, the highest number of shoots was formed at concentration of 30 g ɭ-¹. Lower and higher concentration of sugars lowered the number of shoots produced especially with concentrations of 70 and 90 g ɭ-¹ respectively. Sucrose and glucose culture in supported the greatest rate of proliferation, while the total number of shoots was lowest when the medium was supplemented with mannitol and sorbitol. On a rooting medium supplied with 10-90 g ɭ-¹ of mannitol or sorbitol, the explants did not grow, and subsequently they died after 2-3 weeks. In addition, there were no significant differences between glucose, fructose, and sucrose in the number of roots, number of leaves, and plant height, except in root length which showed some significant differences between these carbon sources. In contrast, there were significant differences between the concentrations of these carbon sources. The best rooting response of strawberry occurred on concentrations of 30, 50, and 70 g ɭ-¹ respectively. At acclimatization stage, the plants cultured in fructose medium produced the highest number of leaves, fresh weight, and dry weight. Moreover, there were significant differences at the final harvest between the concentrations of sugar used. The vegetative growth of the plants was enhanced by increasing the level of sugars (90, 70, and 50 g ɭ-¹) especially the concentration 90 g ɭ-¹ which was the superior to the others.
