A micropropagation procedure for rapid multiplication of strawberry by runner tips is described. The highest regeneration rate and most shoots per runner tips explants resulted on a medium based on Knop medium and M.S. micro element supplemented with (1mg/l) BAP and 0.5 mg/l kn together with glucose at a concentration of 4%. Glucose was more effective than sucrose or a combination of these sugars. Best results on rooting were obtained with Knop salt formulation having 1mg/l IBA. Addition of 300mg/l activated charcoal also enhanced rooting using this produce, 90%. of shoots, rooted. The survival rate at the end of the acclimatization period was 80%.

Knop medium, M.S. medium, Glucose, sucrose, Activated charcoal.
