| 摘 要： | 马尾松是我国重要的制浆造纸原料,分布广泛,生长迅速,数量众多,具有极大的开发利用潜力。由于我国造纸原料中木浆所占比重低(22％),纸浆和纸张质量较低劣,难以满足今日社会发展之需求,因此对马尾松制浆材的开发利用和材性改良的研究近来日益为人们所重视。

| Abstract: | From the study on juvenile wood properties of 26 provenances of masson pine, we found that the effects of provenance variation were small for wood specific gravity (SG) and tracheid length (TL), and differences within provenance were the main sources of variation of both traits. There appeared no latitude-oriented variant model for SG and TL. Because of stronger negative correlation at provenance level and no significant correlation at individual level within provenance between SG and growth rate of height and diameter, we should tentatively select the provenances with high growth rate, and then select individuals based on growth rate and wood traits within provenance selected. Indirect selection cannot be ignored in the program of wood property improvement. |
