- Indirect organogenesis, high frequency callus, Boucerosia procumbens
Abstract
Efficient protocols of callus culture indirect organogenesis were established for mature internodal segments of Boucerosia procumbens (Asclepiadoideae). When MS medium was supplemented with different concentration of auxins, the texture of the callus varied according to the nature of auxin. Optimum callus was developed on MS medium supplemented with 3mg/l IAA. Best response (65%) of callus proliferation was obtained when MS medium fortified with 2iP 2mg/l + Zeatin 0.5 mg/l. IAA was most effective in producing the highest frequency of organogenic culture. Regeneration of callus into plantlets could not be achieved in
the present study. The regenerated shoots were rooted on half strength MS medium fortified with 0.1 mg/l NAA. 57% of the rooted shootlets survived in the field.
