Abstract

The present experiments were conducted in the Tissue Culture Lab. of the Date Palm Research Center, King Faisal University, Al-Hassa, Saudi Arabia. Different concentrations of date palm syrup locally known as (Dibs) (5, 10 and 20%) and sucrose (30 g l-1) as control were used for in vitro multiplication of date palm cv Khanezi. Preliminary observations have shown that lower concentration of date syrup (5%) have successfully induced buds and shoots formation. Higher concentrations (10% and 20%) of date syrup, however, have resulted in browning and dryness of plant materials. This phenomenon was probably caused by osmotic stress due to the use of higher date syrup concentration . The results have also indicated that most of the parameters like number of shoots, fresh and dry weights of culture have increased when 5% date syrup was used compared to control (sucrose 30 g l-1).
