Meristematic shoots can be used for utilization of plant cell biosynthetic capabilities for obtaining useful products from valuable medicinal plant to meet out the pharmaceutical demand and also for studying the metabolism. The medium containing combination of 0.2 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.2 mg/L napthyleneacetic acid (NAA) promoted the highest callus induction at 20%. Transferring the initiated callus on the medium with 1 mg/L 2,4-D enhanced the proliferation rate up to maximum fresh weight of 6.71 gm. Growth curve of cultured cells revealed that the cells continued to grow until 50 days of culture and showed the highest peak (fresh weight) at 40 days in all different initial weight tested ( 0.2, 0.5 and 1.0 gram). Isolated embryogenic callus was found to produce the highest in weight when suspended in liquid medium supplemented with 1 mg/L 2,4-D at 110 rpm resulted 13.5 gram fresh weight and 1080 mg dry weight.展开更多
