Callus formation is associated with the balance between auxin and cytokinin
(TAIZ & ZEIGER, 2013).
Respiration, carbohydrate metabolism, and the action of cytokinins
Secondly, the explants were cultured on MS media including BAP and different type of auxin (NAA, IAA or IBA) to determine the effect of cytokinin
x auxin interaction on shoot propagation.
When used alone, the cytokinin
has also been effective for the cultivation of other forest species such as Cedrela fissilis (NUNES et al.
Many studies have reported the stimulating effect of cytokinin
on in vitro floral morphogenesis, but they were species-dependent [8, 18, 14, 19, 20].
For bioassay of cytokinin
, the radish cotyledon expansion test was employed (Letham, 1971).
play an important role in promoting shoot regeneration through either organogenesis or embryogenesis [10,21].
rosea, respectively, indicating that this cytokinin
can contribute to the in vitro multiplication of plants of this sort.
Cotton is used in textile industry as basic raw material and cytokinins
are being used to increase the cotton production.
These extracts are easily available at economical prices and can be proved helpful to relieve various abiotic stresses including heat stress by promoting the production of auxin or cytokinins
These authors found that a combination of cytokinins
and auxins was not effective in inducing callus formation, as was also reported by Oliveira et al.
In general, gibberelins are involved in the transcription of gene coding; cytokinins
in the translation and auxins in the membrane permeability.
