Somatic embryogenesis in Encephalartos cycadifolius

Plant Cell Reports, 1996
Callus cultures of Encephalartos cycadifolius were established from zygotic embryo explants on a modified B5 medium containing 1 mg l(-1) 2,4-D and 1 mg l(-1) kinetin. Callus was transferred to media containing various combinations of 2,4-D and kinetin for improvement of somatic embryogenesis.

Noninvasive evaluation of somatic embryogenesis

Biotechnology and Bioengineering, 1992
AbstractCallus Suspension Cultures of Ipomea batates Poir. cv. White Star were grown in an airlift bioreactor. A machine vision system was used to monitor nondestructively callus growth during a 10 day culture period. Growth data obtained with this system included the overall reactor population and population estimates for the 200–1200‐μm fractions at ...

Somatic Embryogenesis in Larix

1995
The genus Larix has 10 species and many varieties and hybrids. They are native in the cool-temperate and boreal regions of the northern hemisphere and in the Himalaya mountains (Gower & Richards, 1990). An outstanding characteristic of Larix is that it is the only conifer genus that is deciduous.

Somatic embryogenesis, secondary somatic embryogenesis, and shoot organogenesis in Rosa

Journal of Plant Physiology, 2002
Summary The influence of various 2,4-D concentrations (11.3–181 µmol/L) on induction of callus from leaf tissues of Rosa hybrida cvs. Carefree Beauty and Grand Gala and R. chinensis minima cv. Red Sunblaze was evaluated. Following transfer of callus to a regeneration medium containing different concentrations of thidiazuron (TDZ) (0–90.8 µmol/L), 6 ...

Somatic embryogenesis for agricultural improvement

World Journal of Microbiology & Biotechnology, 1995
Many important food and fibre crops have attained close to their maximum yields as a result of conventional breeding approaches and advances in agronomic and horticultural practices. The manipulation of cell and tissue cultures to produce somatic embryos efficiently is one of the keystones of the new technologies that will greatly alter the way crops ...

Somatic Embryogenesis in Larix Decidua

1991
Success in somatic embryogenesis has been reported for conifer species since few years. Picea abies, P. glauca, P. mariana, Pinus taeda and P. lambertiana as well as Pseudotsuga menziesii have given embryogenic callus from immature and, for some species, mature zygotic embryos.

Hevea : micropropagation by somatic embryogenesis

1997
The different steps of the process for maintained somatic embryogenesis were described. The current yields of the process were shown. They led to discuss on the limiting factors with the prospect of mass micropropagation. The first field trial with five, years old vitroplants was analysed. First conclusions were promising.

Somatic embryogenesis: cell biological aspects

Acta Botanica Neerlandica, 1994
Somatic embryogenesis is the development from somatic cells, through an orderly series of characteristic morphological stages, of structures that resemble zygotic embryos. Structures of somatic origin resembling embryos may form spontaneously on, for instance, leaf tips of Malaxis (Taylor 1967; for review see Vasil & Vasil 1980).

Somatic Embryogenesis Protocol: Citrus

2005
somatic embryo regeneration have involved the culture of isolated nucelli, nucellar embryos, or whole fertilized or unfertilized ovules. As regenerated somatic embryos usually originate fromnucellar tissues, they have a genetic makeup that is identical to that of the plant source, excluding mutational events.

Direct Somatic Embryogenesis

1995
Direct somatic embryogenesis is the formation of somatic embryos or embryo-genic tissue directly from the explant without the formation of an intermediate callus phase (Raghavan 1986). In embryogenesis systems, this is almost always what happens (Merkle et al. 1990; Finer 1994).
