In situ conservation of different cultivars of cassava (Manihot
esculenta) implies many problems such as climatic risks, diseases,
devastators and financial difficulties. This work contributes to the
maintenance of RB 89509 variety of Manihot esculenta through in vitro
culture. Two cultures media were used: medium of Murashige and Skoog
(MS) and medium of Murashige and Skoog (MS) added with activated
carbon. The effects of activated carbon were studied on the growth
parameters (number of leaves, number of roots, number of nodes, height of
stem, length of internodes, length of principal root) of plantlets aged of
twenty months. The results show that the average number of leaves, the
average number of nodes and the length of main root are more significant at
the plantlets present on medium containing the activated carbon; while the
number of roots, the height of stem and the length of internodes are more significant at the plantlets present on medium without activated carbon.
Moreover, it is noted an drying of the plantlets on the medium without
activated carbon. The activated carbon allowed a better conservation of the plantlets. |
