MANILA, Philippines - The Philippines is fortunate to have bamboo growing abundantly almost everywhere. While this plant is available outright in every community, science and technology can further enhance its growth performance and ensure the sustainability of its supply, with bamboo being aptly considered as an alternative to timber.
The Department of Science and Technology’s Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development, through its Forestry and Environment Research Division, has identified bamboo among its priority commodities.
Several technologies have been developed to address various concerns about bamboo.
Among these technologies are propagation via branch cutting from three to four year old culms and one-node culm cutting as well as clump management and suitable cultural treatments for giant bamboo and kawayan tinik.
Branch cuttings from three to four year old culms are the best planting materials for giant bamboo propagation. At least 10 branches can be collected from one culm. Each collected branch should have two to three nodes and live buds.
The branch cuttings develop sprouts seven to 10 days after potting. Proper care and maintenance are observed until the potted branch cuttings are ready for outplanting.
Usually, the potted propagules are ready for outplanting in three to four months or longer.
Kawayan tinik propagation is done through one–node culm cutting.
After a month, rooted cuttings with sprouts are exposed to full sunlight for growth improvement. In six to 12 months, the potted cuttings are ready for outplanting.
Existing old bamboo clumps can also be rehabilitated/rejuvenated through sanitation cutting, cleaning, or fertilizer application.
This offers a quick and cheap means of increasing the supply of bamboo.
