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

Several work report callus formation for other papaya cultivars prior to the formation of somatic embryos, despite of starting from zygotic embryo tissues with embryogenic predetermined cells which ultimately lead to an increase in genetic variability risks. Developmental pathways of somatic embryogenesis. Increased rooting to Oficina Cubana de la Propiedad Industrial.

Such practice normally raises production costs by increasing the number of planted seedlings and their cultivation until removal [3].

Improved protocol for high frequency plant regeneration through somatic embryogenesis in Carica papaya. This has led to the implementation of strategies using molecular markers for sex determination in this species, particularly techniques based on PCR amplification of molecular markers to determine the sex at early stages of development under field conditions [12].

Tissue culture studies on cocoa Theobroma cacao L. The embryos went through four phases; Induction, Formation, Maduration and Mantenimiento which corresponded each one with different media culture. 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.

This work also provided the first report, up to our knowledge, on the use of zeolite as substrate for the cultivation of shoots in vitro, in combination with increased ventilation as it was carried out. Plant Physiol 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.
