Manual del cultivo de cacao. Journal of Virological Methods, Other difficulties come from the influence of environmental factors on the resulting plants, which influence on the growth, development and morphogenesis of shoots and plants generated in vitro mainly during the trophic phase.

En este ensayo se evaluaron como explantes dos estados de desarrollo de los embriones primarios, embriones tipo globular y embriones embriogenesls cotiledonar. Se realizaron 3 repeticiones por tipo de explante para un total de explantes.

Variation of plants derived from indirect somatic embryogenesis in cotyledon explants of papaya.

Agricultural and Food Science These results also accounted for the pioneering studies on the photoautotrophic culture conditions in Cuba for this plant species [17]. Acta Horticulturae Indirect somatic embryogenesis and morphohistological analysis in Capsicum chinense. Plant Cell Tissue and Organ Culture Dentro de las vias de propagacion in vitro de plantas, la embriogenesis somatica ofrece posibilidades de obtener volumenes de produccion superiores en un menor periodo de tiempo vsgetal a un costo mas bajo, lo cual la convierte en un metodo potencialmente mas eficiente que la regeneracion via organogenesis.

Ministerio de Agricultura, Programa para el Desarrollo de la Amazonia. Besides, somatic embryo germination is affected by hyperhydricity and callus formation at the base of the explant, leading to incomplete germination [6], and having the in vitro shoots to be passed to a culture medium for rooting.

A parte de ello se encuentra la variabilidad propia de cada clon discutida anteriormente. Los embriones pasaron por fases que se correspondieron con medios de cultivo diferenciales: This was possible due to the increased ventilation of culture vessels, by capping them with metallic foil paper with two holes.

Another technical difficulty comes from the relative nature of papaya as refractive to tissue culture, with low percentages of in vitro establishment, low multiplication rates and the presence of endogenous bacteria when propagated from cultures under controlled conditions.

These are novel and promising findings which make more efficient the in vitro regeneration system. We also report the first studies in ejbriogenesis under photoautotrophic conditions during the rooting phase, critical for the in vitro culture of this crop.

It is expected that these results could have a positive impact on the propagation of this commercially relevant crop in Cuba in the short time, also setting guidelines for future research on the genetic regulation during SE in papaya species.

Another alternative considers the potential introduction of biologically active substances of national production and available for crop improvement in the in vitro regeneration process of papaya, in order to improve rooting in vitrowhile substituting the import of equivalent foreign products. Un total de 67 plantas fueron usadas para este experimento. The study also provided evidence on the role of auxin transporters at all stages of histological differentiation during the development of somatic embryos.
