Abstract:

A Study on the wood properties of 10-year-old loblolly pine with 18 provenances which intruduced from America grown at same location(Guang Xi, China) was conducted. It include (1) provenancial variation of the wood properties, (2) the geographic variation patterns of the wood properties as well as the relationship between the wood properties and indigenous annual rainfall and average temperature, (3) the correlation analyses among wood properties and between the wood properties and growth and from factors.These researches can help China introduce loblolly pine seed form America and work out suitable tree improvement program of loblolly pine.

Key words: Loblolly pine, Wood basic density, Latewood percentage, Tracheid length, Wood properties variation
