Development of protocol for the production of Acacia
hybrid synthetic seeds
The axillary buds of in vitro Acacia hybrid were cut
aseptically where the explants were placed in the
encapsulation matrix (sodium alginate solution). The
encapsulated explants or synthetic seeds or beads were
cultured onto the tissue culture medium and maintained
in the culture room at 261°C under a 16 hour
photoperiod with a photon flux density of about 35
molm-2s-1 provided by cool white fluorescent lamps to
observe the germination ability of the beads. The beads
are regarded as germinated when the expanded leaves
appeared out from the capsules. Plantlets formation was
observed once the shoots elongated and there were
occasions where roots began to emerge. The synthetic
seeds of Acacia hybrid cultured in vitro sprouted well into
seedlings under suitable conditions. With the ability to
germinate easily, the synthetic seeds production showed
that the main advantage of the system is the combination
of high-volume production and low-cost propagation.
Synthetic seeds of Acacia hybrid can be used as an
alternative planting material meant for forestry sector in
the future and for germplasm conservation.
This technique will become the alternative to high-cost
vegetative propagation technologies. The use of synthetic
seeds will become popular for green house production.
The synthetic seeds of Acacia hybrid have the potential to
be used as a substitute when plants fail to produce seeds
naturally, or when they produce only a small number of
fertile seeds. Direct sowing is possible with the seed sized
propagules, thus eliminating the acclimatization step
normally required in transplanting of mericlones.
Synthetic seeds of Acacia hybrid has a potential in
providing an inexpensive plant delivery system. The
process of planting can be easily mechanised and this
allows the direct delivery of tissue cultured plant
propagules to the field. It also provides rapid bulking up
for the production of individual genetically engineered
plants especially for the highly demanded species. This
may be a reliable method for long-term storage of plant
genetic resources without apparent risk of genetic
instability using minimum space and with lower labour
and maintenance costs.
