Participation of plant hormones in determination and progression of somatic embryogenesis
(2005-11)
In vitro culture protocols have been developed for many species, mainly using empirical approaches, to induce somatic embryogenesis from various explant types. However, the underlying biochemical mechanisms governing ...
Seed germination of pitaya (Hylocereus spp.) as affected by seed extraction method, storage, germination conditions, germination assessment approach and water potential
(2019)
To breed and preserve pitaya (Hylocereus spp.) genetic resources, reliable information on seed storage and germination conditions is needed. Therefore, this study was undertaken to evaluate the effects of the following ...
Vanilla protoplasts: isolation and electrofusion
(2015)
The vanilla plant is an orchid mainly commercialized for the production of vanillin. This compound is considered the second largest natural flavoring source in the world. In recent years, ...
Changes in hormone concentrations during dormancy release of oil palm (Elaeis guineensis) seeds
(2008-10)
Oil palm (Elaeis guineensis) seeds are highly dormant immediately after harvest. In practical horticulture this dormancy has been traditionally overcome by a dry-heat treatment and, more recently, through the application ...
Micropropagación de Guadua angustifolia Kunth a partir de explantes nodales
(2004)
Se evaluó el efecto de diferentes estrategias de desinfección, así como de varias concentraciones de la citoquinina 6-bencilamino purina (BAP) en el medio de cultivo, sobre el establecimiento y desarrollo in vitro de ...

Mode of action of plant hormones and plant growth regulators during induction of somatic embryogenesis: molecular aspects
(2005-11)
Plant hormones play critical roles in the establishment of somatic embryogenesis. During this process, somatic plant cells reverse their state of differentiation, acquire pluripotentiality and set up a new developmental ...
