Growth of C.odorata callus was also determined by fresh and dryvweight measurement .The fresh and dri weight of C. odorata patal-derived callus on medium supplemented with NAA and BAP were recorded every week until 4 week of cultivation time .MS medium ,B5 vitamins supplemented with NAA and BAP showed the highest biomass accumulation compared to other combinations of NAA and BAP. It was observed that fresh and dry weights of callus were increased by cultivation time .There was a gradual increase in fresh and dry weights from day 14 with FW to day 21with FW,and also the increment of dry weight from day 14 with
