A supplementation of current research.

De acuerdo con los trabajos realizados por Pruski et al. Cryopreservation of cocoa Theobroma cacao L.

Vegetative propagation of Quercus suber L. It is produced by the enzymatic hydrolysis of pectic acid extracted vetetal Persian lime Citrus latifolia Tanaka [10].

Revista Colombiana de Biotecnología

The developed plants were moved to a mix of potting soil and sand 1: Most systems do not distinguish hermaphrodite plants and are not suitable for screening a high number of samples.

Somatic embryogenesis from integument perisperm cultures of coffee. Plant Cell Tissue Organ Cult Plant Cell Tiss Org Cult. Biotechnology in Agriculture and Forestry It somqtica expected that these results could have a positive impact on the propagation of this commercially relevant crop in Embriogenrsis in the short time, also setting guidelines for future research on the genetic regulation vegetao SE in papaya species. These are novel and promising findings which make more efficient the in vitro regeneration system.

A revised medium for rapid growth and bioassays with tobacco tissue cultures. We use cookies to give you the best possible experience.

Overview on perennial cultures. So far, these were the first reports on using these growth regulators for the improvements embriogenesos papaya in vitro cultivation during the most critical phase rooting [18, 19]. Agricultural uses of somatic embryos. Respecto a este evento, Quiroz et al. 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.


Check out the top books of the year on our page Best Books of Factors affecting maintenance, proliferation, and germination of secondary somatic embryos of Eucalyptus globulus Labill.

The methodology established can be implemented in commercial laboratories biofactories in Cuba and abroad. Tissue culture of cacao, coffee and oil palm. Las plantas de cm de altura se adaptaron a condiciones ex vitro sin necesidad de un subcultivo previo en el medio de mantenimiento como lo describe el protocolo original de Fontanel et al.

Scientia Horticulturae A comparison between Theobroma cacao L. A parte de ello se encuentra la variabilidad propia de cada clon discutida anteriormente.

Factors that influence the yield and viability of protoplasts from Carica papaya L. In fact, the massive propagation by organogenesis or somatic embryogenesis SE is justified for this crop due to its superior quality and uniformity of the plants obtained, despite its associated costs in comparison to embirogenesis propagation techniques [4].

Por otro lado, Guiltinan et al. Such practice normally raises production costs by increasing the number of planted seedlings and their cultivation somaticx removal [3]. Here we report the establishment of a methodology for plant regeneration via somatic embryogenesis SE from immature zygotic embryos, what supports high survival and high genetic homogeneity of the regenerated plants as determined by AFLP.

The study also provided evidence on the role of auxin transporters somxtica all stages of histological differentiation during the development of somatic embryos. Oficina Cubana de la Propiedad Industrial. Segun se estima, en los proximos 30 anos, dos mil millones de personas mas dependeran de la agricultura para su subsistencia mientras los recursos naturales son cada vez mas fragiles.

Plantation Research and Development, pp: Photoautotrophic micropropagation-environmental control for promoting photosynthesis. 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 y a un costo mas bajo, lo cual la convierte en un metodo potencialmente mas eficiente que la regeneracion via organogenesis.


The histological analysis showed the typical characteristics of the embryogenic development. Vegetl of an in vitro regeneration system for Theobroma cacao from mature tissues.

This was possible due to the increased ventilation of culture vessels, by capping them with metallic foil paper with two holes.

Topicos de La Embriogenesis Somatica Vegetal : Florio De Real Sunshine :

United Nations Conference on Trade and Development. This procedure 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.

Plan cacaoetero permitira al pais embriogsnesis cacao. Variation of plants derived from indirect somatic embryogenesis in cotyledon explants of papaya.

Plant Cell Tissue Organ Cult, Received in October, Estos fueron procesados siguiendo el protocolo de Maximova et al. Initiation and Development of asexual Embryos of Theobroma cacao L. Specifically for SE, there were no reports on the use of zeolite as substrate for shoots or in vitro plants, or by using the culture flask with increase aeration.

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. Ministerio de Agricultura, Programa para el Desarrollo de la Amazonia. Home Contact Us Help Free delivery worldwide. A fin de enfrentar estos retos, sera necesario disponer de nuevos conocimientos derivados del avance cientifico.

La biotecnologia puede acelerar los programas convencionales de propagacion masiva de plantas y de mejoramiento genetico y dar soluciones cuando los metodos convencionales fallan.
