A method is described for the culture and regeneration of plants from callus of sunflower ( Helianthus annuus ) and H. annuus x H. tuberosus hybrids. Immature embryos proved to be the only explant which consistently gave regenerable cultures in all genotypes. The most responsive embryos were app...

Sugar that is included in thermoresponsive hydrogel (TRHG) is excluded during the elevated temperature treatment process. An unexpected effect was discovered when a TRHG rather than an agar gel was used as a culture substrate. To confirm the effect of the thermoresponsive gel described in the ...
Tissue Culture: Plants : A Bibliography, January 1991-April 1993.Henry Gilbert
in plant science, which provides the foundation for further plant tissue culture studies. In nature, soil nourishes plants and provides the basic nutrients for their further growth and development. Apart from carbon, hydrogen, and oxygen, plants require large amounts of elements denoted as major ...
Plant tissue culture techniques are used extensively in the propagation of ornamental and horticultural plants, in biochemical and molecular studies of plant cellular processes, and in plant transformation protocols. Genetic identity among cells or plants is usually desired or assumed in these experiments...
Plant cells in tissue culture are more efficiently transformed in a method which involves treatment with a cytokinin followed by incubation for a period sufficient to permit undifferentiated cells in cotyledonary node tissue to differentiate into meristematic cells and to permit the cells to enter the ...
plants in terms of growth rates and other favorable characteristics have led to plant tissue culture forming an integral part of commercial operations, such as the horticultural, ornamental, agricultural, andforestryindustries. Many examples of this include the propagation ofwoody plantssuch asEucalyptus...
Specialized plant tissue culture methods have enabled the production of completely homozygous breeding lines from gametic cells in a shortened time frame compared to conventional plant breeding. Plants from gametic cells of an F1 hybrid represent a gamet
