Evaluations of the Capacity and the Characteristics of Germination of MyrianthusArboreus (Cecropiaceae)by Cuttings Culture
Keywords:Myrianthusarboreus, Cuttings culture, Regeneration of genotypes, Domestication, Sauce vegetable.
Myrianthusarboreus is a food and medicinal plant. The young sheets, rich in amino-acids and rock salt are consumed out of sauce vegetable and like sauce vegetable. The seed rich in linoleic acid is consumed from Côte d'Ivoire to Congo. In addition, the sheet s, the fruits and the bark have many therapeutic virtues. Thus, the objective of this work is to contribute to the domestication of M. arboreus through his regeneration by cuttings culture. With this intention, three substrates of sowing (red sawdust, black soil and the mixture of black soil and red sawdust, three devices (under light barrier, greenhouse and open sky) and three types of explants (young stem, ripened stem and old stem), were tested. The results showed that the open sky device supports the best resumption of the cuttings culture with a rate of 61.48%. The cuttings culture of the old stem presented the greatest successes (60.37%) and the black soil with 41.85% proved to be the best substrate of sowing. Ultimately, M. arboreus is propagated rather easily.
