Original Research Paper


Dedifferentiated and differentiated tissue cultures ofArtemisia annua L. for artemisinin production were carried out. The calluses were initiated on MS medium supplemented with sucrose (30 g l-1), myoinositol (100 mg l-1) and RT vitamins. The auxins used were naphtaleneacetic acid (NAA), indoleacetic acid (IAA), indolebutyric acid (IBA) and 2,4-dichlorophenoxyacetic acid (2,4-d). These were added to the basal medium either singly or in combination. The best results were obtained with 2.4-d (4.5 μM : μ0.02 d-1) and NAA (5.4 μM : μ 0.06 d-1). Cell suspensions were established on the same media without agar. Suspension cultures showed different morphological characteristics according to the plant growth regulator supplied. Organized cultures were initiated from callus obtained on 2,4-d (4.5 μM) and from bud cultures. Medium containing 6-benzylaminepurine (BA) (8.9 μM)+NAA (0.54 μM); Zeatin (45.62 μM)+NAA (5.37 μM) or BA (8.9 μM) stimulated both organogenesis in callus (frequency of induction =50%) and semi-organized tissue in shoot buds. BA (13.32 μM)+NAA (1.08 μM) or BA (13.32 μM) only stimulated multiple shoot cultures (frequency of induction =80%). Regarding artemisinin content, while the values obtained were 1.13 and 0.78 mg gDW-1 in primary callus, artemisinin was not detected in cell suspension and only traces of it were found in multiple shoot cultures.
