Micropropagation of Gerbera (Gerbera jamesonii Bolus).
In the present study, experiments were conducted to investigate organogenesis from various sources of Gerbera explants. This callus gave the highest dry weight. Combination of auxin and cytokinin induces the formation of adventitious shoots and roots.
Plantlets survival rate achieved was Hook by tissue culture technique. Root explants were found to be non-regenerative in all experiments conducted. Effects of growth regulators and incubation period on in vitro regeneration of adventitious shoots from Gerbera petioles. Adventitious shoots were obtained from petiole explants cultured on Murashige and Skoog MS medium supplemented with 2. Micropropagation and microproapgation plant quality.
However, white, creamy friable callus was obtained when explants were cultured on MS medium supplemented with 2, 4-D alone. Callus with good and compact structure was obtained when explant was cultured on MS medium supplemented with the combination of BAP and 2, 4-D. The mode of action of thidiazuron: Slow-growing endogenous bacteria are one of the most important problems in gerbera micropropagation but require more studies on control and prevention. Most papers in the literature have focused on testing the influence of micrropropagation types and combinations of plant growth regulators with the aim of improving the regeneration and multiplication stage of one or few cultivars.
In vitro plantlet production from young capitulum explants of Gerbera jamesonii. Many scientists have tried to prove the totipotency concept, which is the ability of a single cell to form complete individual. Leaf explants cultured on MS medium supplemented with micropropaagation. Pakistan Journal of Biological Sciences, Numerous types of explants and protocols for micropropagation have been established and used for gerbera.
Root formation occurred when explants were cultured on medium with higher auxin concentration and lower cytokinin concentration. Capitulum explant promoted callus development. High concentrations of cytokinin in culture medium micropropayation found to be unsuitable for shoot formation from leaf or petiole explants in some ornamentals.
Percentage of shoot formation and number of shoots per explants produced on MS medium supplemented with different hormones and concentrations after 8 weeks in culture. In vitro regeneration of Hagenia abyssinica Bruce J. Many commercial ornamental plants are being propagated by in vitro culture on the culture medium containing auxins and cytokinins Preil, ; Rout and Jain, Kajian morfogenesis tumbuhan hiasan Saintpaulia ionantha Wendl.
The physiological status of the donor is microprolagation by environmental conditions such as temperature, light intensity, day-length and light wavelength.
The study was conducted at laboratory B2.
The studing of micropropagation of Gerbera sp via shoot tip explant.
Explants were obtained from 8-week-old aseptic seedlings. Sterilized seeds were cultured on basal MS Murashige and Skoog, medium. In conclusion, the research done has proven that micro propagation of Gerbera jamesonii Bolus ex. Callus is capable of forming adventitious roots. In vitro establishment and plantlet regeneration of Gerbera jamesonii Bolus ex. Tissues of explants generally show distinct planes of cell division, various specializations of cells and organization into specialized structures such as the vascular system.
The effect of cytokinin type and concentration and the number of subcultures on the multiplication rate of some decorative plants.
Formation of callus from explants tissues involves the development of progressively more random planes of cell division, less frequent specialization of cells and loss of organized structures Thorpe, ; Wagley et al.
