With deforestation continuing unabated and the demand for quality
wood remaining on the rise, the success of efforts at regaining
Philippine forest cover may lie on the quality of seedlings
being planted to replace lost vegetation. The UPLB College of
Forestry and Natural Resources (CFNR) has been pursuing this
track of providing quality forest trees and other plants via
tissue culture.
Dr. Portia Lapitan, director of the UPLB Forest Biotechnology
Program, said: "We want planting materials that grow fast
and perform very well under adverse conditions in the field.
Although the work now is still in the experimental stages, the
commercial scale production of quality forest species may soon
be realized."
A tree physiologist and forest geneticist, Dr. Lapitan believes
that biotechnology is necessary to meet the increasing demands
for planting stocks. As of now, the Philippines is said to need
an estimated 195.4 million seedlings a year to meet the annual
planting target for 100,000 hectares. At present, there are
not enough existing seed sources of forest species for reforestation
and production in the country.
In the UPLB campus, the program’s modest laboratory is
home to hundreds of glass bottles with tiny, cloned seedlings
of various tree and non-tree species growing in modified Murashige
and Skoog media. The Forest Biotechnology Laboratory has been
operational since 2002 and has produced a number of valuable
seedlings, all of which have been grown from tissue culture.
The seedlings come from germinated seeds of trees with superior
quality. The tissue-cultured seedlings are expected to reach
maturity earlier and perform better than the conventionally
raised trees. They also retain the quality of the mother tree,
including its disease and pest resistance.
The Forest and Biotechnology Program has developed tissue culture
protocols for Acacia mangium (mangium), Gmelina arborea (yemane),
Paraserianthes falcataria (falcate, Moluccan sau), Tectona grandis
(teak), and Calamus (rattan) species. Future work will include
species such as the Falcata tree (Paraserianthes falcataria),
Jathropa, and the Moringa tree, commonly known as "malunggay."
These will be developed to answer the need for sources of bio-fuel
in the country.
According to Dr. Lapitan, the protocol for out-planting still
has to be refined in order to ensure higher seedling survival.
She and her team of scientists and researchers are now working
to perfect the breeding and biotechnology work to develop and
produce planting materials in order to meet the demand for reinstating
the country’s forests and tree plantations.
At present, the program needs to find continued funding for
its operations, which require around P500,000 to P800,000 a
year. The team is looking at options to make the laboratory
self-sustaining. Currently, it is being supported by donations
from the Department of Environment and Natural Resources and
PCARRD.
