| Abstract: | Cell suspension culture was employed to produce somatic somatic embryoids and theirplantlets from Hevea brasiliensis. The embryogenesis rate was enhanced by addition of 2%glycerine to the suspension medium. The embryogenesis was promoted on the suspension liquid and solid differentiation media at the presence of 1.0 mg/L and 0.2 mg/L of 2,4-Drespectively. The presence of ABA in the solid medium was beneficial for generation ofnormal embryoids which were induced to form plantlets when transferred to modified MSmedia. High concentration of glutamine was conducive to formation of plantlets from thenormal embryoids cultured on modified MS media. |
