| 摘 要： | 以6个22年生马尾松初级种子园半同胞家系为研究对象,比较优良家系、最差家系和对照的生长、单位面积材干物质产量及材性差异。结果表明,不同家系的单株材积、木材密度和木材干物质产量间差异显著;纤维素、综纤维、酸不溶木素、戊聚糖、冷水抽提物、热水抽提物、1%NaOH抽提物、苯醇抽提物、灰分和水分等10个化学组分的含量间差异不显著;单位面积木材干物质产量是马尾松材性改良的首选指标,木材化学组分可作为参考指标。

| Abstract: | Taking six half-sib families of 22 years old Pinus massoniana in seed orchard as study materials,the growth,wood dry matter yield and wood property of different families were compared.Significant differences were found on individual wood volume,wood density and wood dry matter yield between different families.There were no significantly differences between different families on contents of ten components in wood namely,cellulose,holocellulose,lignin,pentosan,cold water extract,hot water extract,1 % NaOH extract,benzene-alcohol extract,ash and water.It was concluded that dry mater yield of wood in unit area was the preferred index for timber property improvement of Pinus massoniana,and the contents of chemical components could be the referenced criterion. |
