Due to various causes, the natural forest area in our country is diminishing day by day, thus reforestation work is of significant and urgent importance. Besides the traditional native tree species planted by our people such as bamboos, pines, dipterocarps, etc…, some species of origin from other countries have also been introduced into our country and Tectona grandis is one of them.
Teak is a large timber species with rather fast growth rather wide ecological range and is naturally distributed in many countries such as India, Myanmar, Thailand and Laos. Tectona grandis wood is used for various purposes such as ship-building, household utensils. Specially, Teak timber has high export value and this species was introduced rather early in our country (about 1930- 1940) in Tay Ninh, Binh Duong, Binh Phuoc, Dong Nai, Daklak, Hanoi, Son La, Lai Chau, Tuyen Quang and Bac Kan. Today, the area of concentrated Teak plantations in Eastern South Vietnam and the Central Highland is about 4,200ha.
However, as the seed selection has not previously been paid attention to and adequately invested, the seed supply for forest planting has been from mass collection, at the same time all-sided technical measures for intensive management have not been applied, productivity of forest plantations is still low (9- 12m3/ ha/ year) and the quality of the plantations is not uniform. Prompted by the demand of production, the Eastern South Viet Nam Forest Scientifis and Production Centre has conducted a research subject: “Improvement of Teak for the Eastern South Vietnam and the Central Highland” with main objective of plus tree selection and establishment of seed orchards for these two regions.
