Las plantas enraizadas se llevaron a una mezcla de tierra: A parte de ello se encuentra la variabilidad propia de cada somativa discutida anteriormente. Visit our Beautiful Books page and find lovely books for kids, photography lovers and more. Agricultural and Food Science Effects of different culture conditions photoautotrophic, photomixotrophic and the auxin indole-butyric acid on the in vitro acclimatization of papaya Carica papaya L.

Photoauto- ,Photohetero-and Photomixotrophic in vitro propagation of papaya Carica papaya L. Such changes generate variations in the quality and size of fruits, influencing crop yields. Somatic embryos, rooting, Floroglucinol, photoautotrophism, in vitro acclimatization, zeolite.

Somatic Embryogenesis in Cacao Theobroma cacao. 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.

The developed plants were moved to a mix of potting soil and sand 1: The Best Books of Tissue culture studies on cocoa Theobroma cacao L. Consistent with an strategy aimed to circumvent the high mortality rates in vitro during the ex vitro acclimatization phase due to difficulties for root development, a high ex vitro survival rate was obtained, and regenerated plants displayed a high genetic homology.

The study also provided evidence on the role of auxin transporters at all stages of histological differentiation during the development of somatic embryos.

Respuesta de Clones de Cacao Theobroma cacao L. These results also accounted for the pioneering studies on the photoautotrophic culture vgeetal in Cuba for this plant species [17]. Scientia Horticulturae Initiation and Development of asexual Embryos of Theobroma cacao L. Development of Cassava Manihot esculenta Crantz. Accepted in March, These are novel and promising findings which make more efficient cegetal in vitro regeneration system. Manual del cultivo de cacao.

Plant Physiol One strategy effective to circumvent these problems is the use of in vitro culture techniques, either to produce a high number of plants high quality vegetal material to be planted or to support genetic improvement programs and the commercial introduction eomatica new or hybrid cultivars. Thammasat Int J Sci Technol.

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 seed propagation techniques [4].

It is produced by the enzymatic hydrolysis of pectic acid extracted from Persian lime Citrus latifolia Tanaka [10]. Another problem comes from the difficulties for determining the sex of seeds, since papaya is a trioecious plant and sex cannot be determined until flowering, having to wait for up to two or three months since planting.

INCI30 We also report the first studies in papaya under photoautotrophic conditions during the rooting phase, critical for the in vitro culture of this crop. The embryos went through four phases; Induction, Formation, Maduration and Mantenimiento which corresponded each one with different media culture.

The histological analysis showed the typical characteristics of the somatiac development.

Picomolar concentrations of salicylates induce cellular growth and enhance somatic embryiogenesis in Coffea arabica tissue culture. Such practice normally raises production costs by increasing the number of planted seedlings and their cultivation until removal [3].

Hystological changes and reseve acumulation during somatic embryogenesis in Eucalyptus globulus. The methodology developed was supported by histology and electron microscopy studies, and provides a consistent tool to increase the efficiency of the propagation process.

Trop57 1: Dispatched from the UK in 3 business days When will my order arrive? Effect of phloroglucinol on rooting and in vitro acclimatization of papaya Carica papaya L. The methodology established can be implemented in commercial laboratories biofactories in Cuba and embiogenesis. Cocoa Anual Report Disponible en http: Photoautotrophic culture provides several advantages, including growth and photosynthesis stimulation, high percentage of survival during the in vitro to ex vitro transition, the correction of physiological and morphological disorders in the cultured plants, avoids callus formation at the base of the explant what increases rooting, and reduces the losses due to microbial contamination.
