摘要:

对生长于广西南宁地区相同环境下来自美国的18个种源10年生火炬松的材性进行了研究, 包括:材性的种源变异, 材性的地理变异模式及其与原产地气候因子的相互关系, 材性因子间及其与生长因子、形态因子的相关分析。为我国火炬松种子引进和调拨以及林大改良计划的制定提供了依据。

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
