Conversely, few reports are available on the secondary multiplication of primary somatic embryos, a phase considered crucial for high multiplication rates in SE. The methodology developed was supported by histology and electron microscopy studies, and provides a consistent tool to increase the efficiency of the propagation process. Looking for beautiful books? Another product to be considered is phloroglucinol PGa phenolic compound obtained by degrading floridcin and a precursor in the synthetic pathway of lignin.

Esto es coherente con los resultados obtenidos por Traore et al. There are also few reports on the obtainment of secondary multiplication from primary somatic embryos, as a key phase to generate higher number of plants in SE.

Plant Cell Tiss Org Cult. This is further amplified by difficulties in rooting due to the lack of a basal callus, what hamper or limit the direct connection vegwtal roots with the stem, ultimately causing high losses during acclimatization by limited ex vitro rooting.


Accepted in March, The study also provided evidence on the role of auxin transporters at all stages of histological differentiation during the embriogenedis of somatic embryos. Respecto a este evento, Quiroz et al.

Factors affecting secondary somatic embryogenesis and embryo maturation in Morus alba L. Variation of plants derived from indirect somatic embryogenesis in cotyledon explants of papaya. Use of secondary somatic embryos promotes genetic fidelity in cryopreservation of cocoa Theobroma cacao L. Plant Cell Tissue and Organ Culture Los embriones pasaron por fases que se correspondieron embriogeesis medios de cultivo diferenciales: Domatica in plant tissue culture.

Photoautotrophic micropropagation-environmental control for promoting photosynthesis. Factors that influence the yield and viability of protoplasts from Carica papaya L. According to Kozai [8], in vitro photoautotrophism can be induced by excluding carbohydrates from the culture medium and by increasing gas exchange in the culture vessel.

This veegtal allowed us to improve the quality of the plants obtained with a better ex vitro acclimatization of in vitro obtained explants, and higher survival rates. In Cuba, in this crop provided yields of tons, with a cultivated surface of ha [2]. En el pulso de 0.

So far, these were the first reports on using these growth regulators for the improvements of papaya in vitro cultivation during the most critical phase rooting [18, 19]. Initiation and Development of asexual Embryos of Theobroma cacao L.

Las plantas enraizadas se llevaron a una mezcla de tierra: Se realizaron 3 repeticiones por tipo de explante para un total de explantes. The high nutritional value of papaya is the basis for a variety of food and medicinal applications [1].

Photoautotrophic micropropagation for rooting and increased ex vitro survival rates The photoautotrophic culture has several advantages, such as stimulating plant growth and photosynthesis, together with an increase in survival rates during the in vitro – ex vitro transition.

All this has led to the preferential use of SE for papaya propagation and its genetic improvement.
