Summary<\/b><\/p>\n

This paper discusses the growth, characteristics of the wood of Acacia auriculiformis, Acacia mangium, Acacia hybrid collected from seven-year-old plantation forest in \u0110ong Ha, Quang Tri.<\/p>\n

The reported data show that at the age of seven, Acacia mangium<\/i> can reach about 16.28 cm in diameter, Acacia hybrid<\/i> – about 14.87 cm, Acacia auriculiformis<\/i> – about 13.02 cm in diameter at breast height of standing trees.<\/p>\n

Oven-dried density was lowest near the pith, and increased towards sapwood. The results of the study indicated that the incidence of heart rot has appeared in A. mangium<\/i>. In the seven-year-old forest plantations, 40% of the trees of Acacia mangium<\/i> have already been affected by heart rot.<\/p>\n","protected":false},"excerpt":{"rendered":"
