Culture Systems

The objective of this study was to examine the effect of two culture systems, liquid medium associated to floating membranes and solid medium, both supplemented with different concentrations of 2,4-D, in the induction of somatic embryogenesis of cassava (Manihot esculenta Crantz). Only 28% of the young leaf lobes (with 9 µM 2,4-D) were induced to form organized embryogenic structures (OES) with membrane rafts, compared to 50% of the explants presenting this type of tissue in solid medium with 36 µM of 2,4-D. Despite the lower response observed in liquid medium with membrane, the amount of OES/explant in all 2,4-D concentrations was higher than solid medium. Based on the results and considering the high cost of the membrane rafts, this system was not distinctly superior than solid medium for inducing somatic embryogenesis in cassava.

Somatic embryos of cassava var. KM297 received from pieces of in vitro immature leaf lobes or cotyledon of somatic embryos, were induced on the MS medium supplemented with 8mg/l picloram after 13 days inoculation in the dark condition. Different states of embryo were obtained after 10 days cultured on MS medium supplemented with 0.1 mg/l BA and 0.01mg/l NAA, in the light condition. Role of endogenous AIA and Zeatin of the globular state of embryos was studied.

The embryogenesis (SE) has important role for genetic engineering of cassava (Manihot esculenta Crantz). However, the success of SE induction depend on plant growth regulator s (PGR)s and treatment enriched in induction media.  This experiment tried to induce callus formation of cassava from several in vitro explants: immature leaf, apical bud, and internode; and to develop somatic embryogenesis of cassava in several media enriched with tyrosine and copper sulphate (CuSO4) added into media enrich with picloram as treatment.  Different response of explants source to callus induction treatment from those three varieties in callus induction as well as friable callus formation were found in this experiment. The best medium to induce varied with variety; MS media supplemented 12 mg/L picloram + 0.5 mg/L CuSO4 was the best for “Adira 4” and  half MS and half GD media supplemented 12 mg/L picloram + 100 mg/L tyrosine for “Malang 6”.  All treatments resulted somatic embryo which developed indirectly and in morphologically normal somatic embryos
