SUAREZ GUERRA, Lorenzo  and  HERNANDEZ ESPINOSA, María M. Effect of the Pectimorf^® in meristem tip in vitro culture cassava (Manihot esculenta Crantz), clone´CMC-40´ and ´Señorita´. cultrop [online]. 2015, vol.36, n.4, pp. 55-62. ISSN 1819-4087.

The development of more efficient and more sustainable methodologies in the material obtaining yucca (Manihot esculenta Crantz) in vitro, the improvement of the quality of the seed and vegetable material sanitation, are the objectives of this work to evaluate the effectiveness of Pectimorf^® (mixture of oligogalacturonides), innocuous and natural substance taken place in Cuba, to be used as possible complement or substitute of the growth regulators used traditionally in the propagating medium of yucca meristematics tip. It was demonstrated that Pectimorf^® in the means of cultivation, possible to establish in vitro of the meristem tip cultivation in yucca clones ´CMC-40´ and ´Señorita´ and it stimulated the explant growth too. The results contribute to understand the mechanisms of action of this substance and their future application in vitro plant resorts in Cuba

Keywords : oligosaccharides; cultivation medium; meristems.
